Are you sure it isn't just condensation? A leak will not go away. If condensation, nothing to worry about. It will go away.

Water flows out the condensation tube even when the heater is not runiing causing the pool to leak down. The heater is 4 years old. Thank you.


It sounds like there is a leak in your system. The condensation tube is to drain off the water because one of the byproduct of combustion is water and it condenses on the heat exchanger. Since it is only 4 years old it might be under warrantee for this issue. The problem might be simple but could be very expensive if the heat exchanger has a leak.

I have an Audi 90 1995. There is an oil leak behind the water/oil heat exchanger. I put in a new gasket but still a slight leak. What's the fix? Thanks.


basically check the surfaces are flat...pull the heat exchanger off and run a metal ruler or square across them, if there out gently run a flat file over them, if not put some silicone based chemical gasket around there and should take it up, good luck :)

The rubber gasket around the drum opening is leaking and rusting


You can replace it by lifting the lip of the rubber around the edge and finding the wire where the springs connect there you can stretch the springs apart, remove the wire and pull off the rubber. Just make sure first that is where the leak is, sometimes a leak in the soap dispenser water tube can seem like door gasket leak.

Water is leaking from inlet/outlet area. is that a heat exchanger problem?


If there is a water leak in between the pool/spa plumbing and the inlet/outlet manifold, it just needs a new gasket if it is a plastic manifold, and if it is a cast iron manifold, the 2" threads for inlet and outlet need to be unthreaded, then coated with a pipe sealant (non-teflon) then rethreaded.

If this leak is in between the outer and inner inlet/outlet manifold peices, then a new gasket is needed. The part number for that gasket is: 006713f.

If the leak is coming from inside the cabinet and leaking down the interior or exterior, it could be a heat exchanger issue.

The most likely event is that the o-ring that seals the header manifold is worn and needs to be replaced.
This would take about 30 minutes of labor and an o-ring.

This is likely a leaking heat exchanger. These usually fail due to improper water chemistry. This can happen in less than a year if the chemistry is messed up enough. Most culprits are putting chlorine tablets in the skimmer and running the pH or Total Alkalinity tooo low. HTH

LLD125 pool heater leaking water from inside


My heat exchanger was cracked. I found an old welder who knew how to weld the cracks for $100 vs $900 for a new exchanger,. Also ordered replacement seals for the 2 chambers. I used high temp automotive engine sealant as an additional sealant precaution. Also inspected tubes and cleaned corrosion. Works fine last 3 years. Takes some mechanical skills.

Water is leaking out of the far right burner tube, while pool pump is running.


sounds like you either have a pinhole in your heat exchanger or possibly a bad tube washer (seal). A pinhole can result from poor water chemistry or chemical exposure such as pH chronically low or a chemical feeder (chlorinator or salt cell) installed near the heater without a chemical resistant check valve. You will have to dismantle the heater far enough to access the heat exchanger and inspect it while the pump is running. If it's a pinhole in the exchanger, you will need a new exchanger. If its a seal, you will just need a new set of seals (washers) for the exchanger manifold.

Water leaking


Hi

There are several things to check for: The condensing defrost tray under the fridge can crack or develop a hole and leak onto the floor. A door gasket not closing properly may cause sweating and leak onto the floor. Some fridge's have a humidity switch inside the fridge that should be turned on to prevent sweating on the center bar between the fridge and freezer section. If your fridge has developed a frost free failure problem, often the frost will travel down the suction line at the back of the fridge and drip water on the floor. The heat exchanger tubing can separate and also sweat and drip on the floor. A kit to repair a separated heat exchanger line, comes with instructions as well. Ice maker and chilled water fill lines can crack and leak as well, this is fairly common with the plastic lines as they can dry out and crack.

Please revert for any clarification.
A Fixya rating would be appreciated if you found this to be helpful.

Thanks
