How to treat
and repair spa, swim spa or hot tub leaks?
Spas and hot
tubs can develop leaks as the result of routine
wear and tear, carelessness, accidents or the
effects of wintertime damage. Not all loss of
water can be attributed to a leaky spa or hot
tub. Losses, due to evaporation, splash out or
prolonged uncovered periods are normal and are
expected. Excessive water loss, more than
approximately 1/4" daily, should be
investigated, unless the unit is covered for
long periods of time. Products are available to
help determine if there is a spa or hot tub
leak, where the leak is located and to help seal
the leak. There are companies that specialize in
spa or hot tub leak detection and repair. If

Fix A Leak - Feedback
Problem-Solving Information, in a question and
Locating The Leak?
I have a 375
gallon spa and it has a small leak.
Locating the leak is a problem,
because of the insulation and I
don't have access to all sides of
the spa. Would Fix A Leak
work? Thank you.

might start by removing any wet
insulation, that coats the shell.
Water travels, go the leak might not
even be where the
insulation is wet.
Fix A Leak forms a crust, as it
leaks out. This needs to dry
out and cure to make a long lasting
seal. Having limited access,
to the surround, does not help.
When not running the pump, open the
cabinet and use a fan to help dry
the underside. If you ever
need a new spa, think
Spas. Instead of
insulating the shell, they chose to
insulate the entire cabinet and
specially designed floor. In
addition, you can access all four
sides, as the insulated panels are
removable. With a Arctic Spa,
if there is ever a problem, access
and serving is much easier.
Fix A Leak is certainly worth a try
and can be very successful, as the
fan mail will attest to that.
The truth is many spas might have
been designed better, but the bells
and whistles come first. I
hope that this will be helpful and,

► How Much FIX A
LEAK To Use?
I have a 400 gallon spa that leaks
around a couple jets. Is 2 to 3 oz. of Fix A Leak all I need
Steve and Pam, 7/14/2015
It is suggested that you use about 8 ounces of
FIX A LEAK
product. The use of more product might require that you
empty and clean the spa. Being that the spa leak is around
the return jets, if your spa has a sprayed on type of inner
insulation, you might want to drain the spa and leave it
empty for 3-4 days before beginning. This will allow the
insulation to dry out. Otherwise, the damp insulation could
interfere with the curing process. Use this link, to browse
through more complete and supplemental directions. I hope
that the information proves to be helpful.
Sincerely. Alan Schuster, 7/15/2015
Hi Alan - Greetings from Prescott, AZ.
We had water oozing from underneath the spa and
Fix A Leak
did exactly that! Fixed the leak. Great news, considering
the alternatives. The question is: Can I safely drain the
spa onto the ground without endangering the trees that are
downhill from the spa site? Any other environmental problems
with siphoning onto forested areas? Again, thanks for
recommending such a great product.
Steve R., Prescott, Arizona. 6/20/2017
Once you adjust the pH of the spa, the Fix A Leak, present
in any discharged water, will be harmless. The only common
chemicals to be concerned about are chlorine or bromine and
these should not cause a problem, so long as the level is
not overly high. Glad to hear that the
Fix A Leak product
succeeded in solving the problem.

Allan W.. 4/7/2013
It is probably a pinhole. that leaks when the water is under
pressure: the pump is on. This type of spa leak does respond
to Fix A Leak. It is certainly worth trying. Remove the
filter cartridge and slowly pour into the skimmer, with the
filter running. Keep it running until the spa leak stops.
while stirring the bottom occasionally. After the spa leak
stops. shut off the spa, for 2-3 days. LEAVE THE CABINET
DOOR OPEN AND VENTILATE WITH A FAN, IF POSSIBLE. After
adding the product, operate the pump for an few hours at a
time, spaced throughout the day. Use a brush to help stir
the bottom, as the product is heavy and will sink. When
possible open the cabinet doors, to help dry out the
product, as it leaks out, which helps make a long lasting
seal. Wait a few days before restoring the system, in order
to give the product a chance to cure. Inasmuch as spas
should be drained periodically, this would be a good time to
drain and clean and allow a few days for the underside to
dry out. I hope that this solves the problem.
Sincerely. Alan Schuster, 4/8/2013
Alan, I just wanted to let you know
Fix a leak and your suggestion worked great! It's been two

► Time For
I have a large Spa, 640 gallons, and
have used Fix A leak. It stopped the leak and I let the spa
sit for 3 days then drain and refilled the spa ,after that I
still had a leak, so I have just done the process again. I
used 12-14 oz of Fix a Leak and the spa has not lost any
water in 48 hours. Should I wait a couple more days before
draining and refilling? Do you see anything I could have
done better? Thanks.
Bill M., 4/11/2007
It is a good sign the spa leaking has stopped. Now you need
to get the product to cure and for that it needs to dry out
completely around the site of the leak. Open the cabinet and
allow air to circulate freely. If possible remove insulation
around the leak. Use a fan to blow air in, if these are dead
zones. Give it 2-3 days for the
Fix A Leak to cure and then
empty and clean the spa. I hope that it all turns out well.

I have a 5-6 person hot tub outside in
North Dakota. Our temperature is dropping and my hot tub is
leaking. I have had so many problems with it this past year.
Put in a new circuit board and new pump, 2 new sensors and a
flow switch. It was finally up and running and has now
started to leak, approximately ½ - 1 inch per day. There is
no water in the equipment compartment. I removed one side
panel and could not see any plumbing - it has that sprayed
in insulation. It sits on my deck and I can see water
dripping underneath. Is this something that the fix-a-leak
stuff would fix? Thanks much.

Sincerely. Alan Schuster, 10/12/2010
Alan, I purchased a bottle of
Fix-A-Leak last month hoping to repair a leak in my 8-year
old spa. The spa developed a leak 2 years ago around several
fittings and had to be shipped back to the factory for
repairs. And because of the foam insulation, there is no way
I could have located or repaired the leak myself. It cost me
$900.00 to have the unit craned out and back into to my
backyard the first time, but fortunately, it was still under
warranty so the repair was free. With the warranty now over
who knows what this repair would have cost. I applied the
FIX A LEAK product, per the instructions and no more leak.
The supplemental instructions, you
supplied, were very helpful. It saved me
the cost of factory repair. Thanks.

Good day, I live in Wichita, Kansas
and I have an inground spa which is leaking. I have been
told that the product Fix A Leak from Marlig Industries will
remedy this situation. The leak rate seems to be the same
with pump on or off or on high or low. Do you think this may
solve my problem? Do you have any other suggestions other
than removing the shell from the hole to try to find the
leak and repair it? Thank you for your time and assistance.
David J., Wichita, Kansas, 4/13/2011
It is probably not a major spa leak: just the type that
could be sealed by the FIX A LEAK product. It can make a
long-lasting seal, in a small spa leak, possibly as big as
1/8". It is certainly worth trying, given the modest cost
and the alternatives. Pool-spa leak detection services can
help locate the problem and minimize the repair efforts,
should other efforts prove unsuccessful. I don't know of any
other options. Good luck.
Sincerely. Alan Schuster, 4/14/2011
This afternoon, I purchased a 8 oz
bottle of Fix A Leak. When using this product, does the
water in the hot tub have to be hot or cold? At this time
the water in the tub is clean cold tap water. approx temp
52° F. The tub capacity is 250 gallons, so I understand that
I would only need to add 4 ozs., initially. I would
appreciate your reply. Thank you.
Derek S., Canada, 11/15/2008
This is a really good question and I was surprised that it
was not asked sooner. I checked with the manufacturer and
was informed that FIX A LEAK can be used at typical spa
temperatures, It is recommended that the water temperature
be in the 70° F or above range. In your case, the water
temperature should be raised. Good luck and thanks for

► Where To
Purchase Fix A Leak?
Could you give me the name of location
where I could buy Fix A Leak. My spa has a leak, in a area
that is hard to reach and I thought that I would give it a
try. My zip code is 11746, if that helps.
Sam K., Dix Hills, NY 9/5/2010
For local dealer availability, call 905 374-2560. They might
be able to provide you with the necessary information.
Because they sell through distribution, they don't always
know the names of local dealers. Otherwise, you can
order Fix A Leak from this website. It will ship the
same or next business day. I hope the information
helps solve the problem.
Sincerely. Alan Schuster, 9/5/2010
► Slow Spa
I have a slow leak in my hot tub. I
have found the leak, it is where a hose connects to a jet.
My question is, will the leak stop stuff fix something like
that or any idea how to get the hose out and reseal it? I
don't want to seal it from the outside of the tube. Thanks.
Fix A Leak can seal hot tub leaks as big as 1/8" in
diameter. It seals, as it leaks out of the spa and forms a
permanent seal from the inside out. After the product is
added, bypass the filter, keep the water turning over every
now and then, in order to keep the product suspended. Once
the hot tub leak stops, open up the cabinet and allow the
product 24-48 hours to cure and make a very long-lasting
seal. If this fails, you might have to do more extensive
searching or consider calling in a professional pool-spa
leak detection service. Good luck and I hope that this
information will prove helpful.

► Spa Water
I have noticed approx. 3 inches of
water loss per week in my 400 gallon hot tub. It is outdoors
and it has been cold. I have a good cover. Is this normal
water loss or could it be a leak? Thanks.
I don't recall ever seeing figures for water loss for a spa
that remains properly covered, except for periods of actual
usage. From my own experience, it seems to be well beyond
what should result from evaporation. Depending upon the size
and shape of the spa, an inch of water loss could amount to
10-20 gallons. I suggest that you double check that the
cover is sealing reasonably well and then start looking for
evidence of a spa leak. In the final analysis, if you
conclude that there is a probability of a spa leak, it may
be possible to seal the spa leak, but you have to locate
it. You might consider calling in a pool-spa leak detection
specialist. First, you might consider using
Fix A Leak, which
just might solve the problem, at a fraction of the cost. Good luck.

► Leaky Spa?
to have a leak that allows water to accumulate under the spa
cabinet. I can't see the source and it is not severe, but
I'm afraid that given time it will cause rotting and mildew.
Any suggestions? Thank you.
Ted, Vermont, 2/2/2014
There is a product called FIX A LEAK that can be used to
help seal the spa leak. The product directions will explain
how it should be added to seal leaks that might be in the
plumbing, shell or installed fittings. It has been sealing
spa leaks since 1980. Hopefully, your problem will be
solved. I hope that I have been helpful.

Flow Stopped Leak?
Hi Alan, Greg B. here. We talked
before. I ran my hot tub for about four hours. The water
level stayed where it was. After letting it sit for a couple
of hours, I noticed the water level had dropped. So from our
previous talks, I assume I have a suction leak. I reversed
the lines on my pump, took out the filter. I put in 12oz. of
Fix-A-Leak. Turned the pump on for around 3 hours then shut
it off. I check the water level and was still the same. I
checked back in 3 hours and it was still the same. Checked
the next day in the morning and after I got home from work,
still at the same level. It looks like the leak has stopped,
but not really sure what the next step is. I don't
understand how the Fix-A-Leak can set-up and get hard, if it
is still submerged in water. Can you let me know what to do
Greg B., 2/4/2009
It is simpler than you think. As the water leaked out, the
Fix A Leak formed a crust, which sealed up the hot tub leak.
This crust is outside of the hot tub and is not in contact
with the water. Now you have to give it a few days to
thoroughly cure. Remove any wet insulation and ventilate the
cabinet, with a fan, so that things can completely dry out.
Occasionally, stir the hot tub. In a few days, drain and
clean the hot tub. Rinse the filter, as well. Lets hope
that, after refilling things, stay dry. Good luck.
Alan Schuster, 2/4/2009
► Is There A
I have a fiberglass "jogging tank" in
my basement, a 34 inch diameter, 6 foot cylinder with spa
heater, pump etc. I calculate this tank holds 255 gallons
using 5.5 feet of water. Surface area is 6.21 square feet.
It heats rapidly to 93 degrees from the low 80s. Ambient
inside temperate is around 70 degrees. It loses 1/16 inch
each hour without the pump (covered with a 3/4 inch diameter
plastic bubble sheet) and 1/4 inch per hour while pumping
and heating. The contractor who just installed the system
believes the problem is all evaporation. I believe a leak is
present. I am reluctant to use "Fix a Leak" without knowing
exactly the problem, IE what if it works for only a short
period and also I am not certain that this much water under
my house is a good thing. Your opinion and advice will be
greatly appreciated since the contractor is reluctant to
really search and repair a leak. Your site is a great source
and I appreciate your efforts. Thank you.
Garrison W., Tryon, NC, 2/14/2005
I can't definitively state that you have a spa leak.
Evaporation just cannot be excluded. I suggest that you do
the following and let the facts speak for themselves. Mark
the water level with a line on a piece of tape. Cover the
unit with a solid plastic sheet and seal off with duct tape,
making is as airtight as possible. Give it a day and see the
results. If there is a loss, you have the answer: a spa
leak! If there is no loss, repeat the procedure, with the
pump running for a few hours. This time, if there is a loss,
the problem is in the plumbing system and
FIX A LEAK might
be worth a try. I understand that you are, rightfully,
concerned about water under the basement, but you are
neglecting water vapor in the basement. I suggest that you
use a cover a bit more effective than some bubble film. Good
luck and I hope that I have been helpful.

Cracks And Leaks?
I own a 500 gallon above ground hot
tub. This spa is famous for spider cracks in the front wall
where the step and light are located. Spider cracks form
because of the bad design, no insulating foam or support in
the pump compartment and a large jet shakes the wall. Has
been repaired, but continues to form new cracks. I was
considering dumping it in a landfill, but heard of the Fix A
Leak product. In this case, would Fix A Leak be effective?
Great endorsement for the spa company! It sounds like you
have been down the road. Who is the manufacturer?
Fix A Leak
could very well
make a very long-lasting seal. I can't
guarantee a new crack won't form, but it is worth trying.
Have you ever considered painting the spa?
Ultra Poly One
Coat is a high tech, hybrid epoxy coating that might seal
the surface on a more permanent basis. Sealing first and
then applying the coating could be the way to go. Good luck.
Sincerely. Alan Schuster, 3/28/2007
► Jumping The
Hope you can answer this one. We are
in the process of having an inground pool and spa installed.
They have done the dig, the gunite, the tile and the
plumbing so far. My question to you is twofold: First of
all, we live in Florida and since there is not much space
between the houses, we paid extra for a "small dig" machine
to do the dig. They started with the "small machine" dig and
found that it was taking too long, so, they stopped with the
small machine, after two hours, and brought in a big machine
to do the dig. They advised us that they do not owe us any
money back for bringing the big machine in instead of the
My second question is: We have a pool
and a spa. The spa is level with the pool. My husband
decided to put some water in the spa. It has been five weeks
since the gunite was done and there is a leak from the spa
wall into the pool. In approximately a 5 hour period the spa
leaked about 10 inches of water into the pool area. Again,
the pool and spa have not had the exposed aggregate finish
applied yet, but I was wondering if I should advise the pool
company of the leak. They really are not very cooperative,
so I didn't call them about this. If you think that it is
something that will be "fixed" once they apply the finish.
Any assistance would be appreciated. Thank you.
Pam M., Florida, 1/19/2005
Based on the first question, their actions border on
questionable. You're paying for their mistake or to speed up
their work. Of course, you will recommend them to all of
your friends? They evidently don't realize that today's
recommendations are the sales of tomorrow. There may not be
anything wrong with the spa. It is the pool and spa finish
that makes the concrete shell watertight. Inasmuch as the
pool and spa remain unfinished, the leak might be normal and
not unexpected. There's no way to be sure at this time.
After the pool and spa are plastered, all leaking should
stop. If not, there is a problem. Good luck and I hope that
I have been of some assistance.
Sincerely. Alan Schuster, 1/19/2005
► Leak Has
Stopped - Do I Drain?
Hi, I just used
FIX A LEAK in my hot
tub. Amazing! The dripping is gone, thank you. Now do I need
to drain my tub?
Drake N., Quesnel, BC, Canada, 10/24/2006
That's great news. As far as I am concerned, a spa should be
drained and cleaned every few months and this is a good time
to do it. I would give it 48 hours and then drain and clean.
