Why Does My Pool Heater Leak Water? [Answered!]

Not all water heaters are made equal. Some can leak, even if they are properly installed and tested for leakage. If your pool water heater is leaking at a rate of more than 1 gallon per day, it’s time to find out what’s causing it and take appropriate action. Here are some of the most common causes of pool water heater leak.

Incorrectly Sealed Tank

If your pool water heater doesn’t have an internal baffle system, then it’s time to upgrade. During installation, the installer must make certain that the tank is properly sealed so that water does not escape and cause damage. If the installer doesn’t do his job properly, then that’s one probable cause of your pool water heater leaking. If it’s a DIY project, then you’ll have to do it yourself as it’s rather difficult and time consuming to locate a qualified installer who specializes in installing gas-fitting appliances.

Improperly Installed Pressure Reducing Valve

Another common cause of pool water heater leaks is the installation of the pressure reducing valve. When the valve is installed, it must be positioned perpendicular to the direction of the flow of water to ensure that the water passes through it smoothly. If the installer doesn’t follow the correct procedure, then you could have a serious problem on your hands. It’s also important that the fitting that connects the valve to the pool water hose be tightened properly to avoid leakage. If you feel that the valve could be a potential cause of your pool water heater leaking, then it’s time to replace it.

Faulty Drain Pipe

There are several different types of drain pipes made for septic tanks, water heaters, and similar plumbing fixtures. If your pool water heater is accompanied by a sump pump, then the drain pipe connected to the sump pump could be the cause of your water leaking. If the toilet sheath is made of plastic, then it could be a weak link in the chain that leads to your pool water leaking. When disassembling your toilet, you’ll have to take care not to damage the plastic sheath, as this could lead to more serious leaks in the future. It would also be wise to shut off the water supply while you’re there so that you don’t end up with water damage from a burst pipe. If you replace the drain pipe and it doesn’t solve the problem, then it’s time to locate the source of the leak and repair it properly.

Worn-out O-rings

Another common cause of pool water heater leaks is worn-out O-rings that were used during installation. If the O-ring that connects the gas supply to the valve becomes worn out over time, then it could begin leaking. It would be wise to check the O-rings periodically and replace them if they become worn out. It’s also important to have replacement parts on hand so that you don’t have to stop and wait for the part to be delivered. If you’ve had this problem for a long time and don’t know what could be the cause, then it’s time to replace the O-rings.

Corrosion

Your pool water heater could be at risk of corrosion if it is not installed in a watertight manner or if the tank is not built from quality materials. One of the most common causes of pool water heater corrosion is metal fittings and valves that are exposed to the elements. To avoid this problem, use corrosion-resistant materials and install the pool water heater where there’s adequate ventilation. You could also consider adding an internal water filter in the future to prevent the need to change the water frequently. If you suspect that your pool water heater is at risk of corrosion, then it’s time to examine it closely for any leaks or damage that could be the cause of your problem.

Faulty Valves

A faulty valve could be the source of your pool water leaking issue. There are several different types of valves made for different kinds of plumbing fixtures and water heaters. If you have a ball valve, then it could be out of adjustment or leaking because it was installed improperly. You could also have a gate valve which, when installed properly, will stop virtually all water flow. If you feel that a valve could be the source of your pool water heater issue, then it’s time to replace it with another type.

The best way to stop your pool water from leaking is by finding out the root cause of the problem. If you suspect that your pool water heater is at risk of flooding or overflow damage, then shut off the water supply and call a professional. Not all water heaters are created equal, and some can cause more damage than others if not installed and maintained properly. If your pool water heater is accompanied by a sump pump, then make sure that the drain pipe is clean and unclogged, and that the pressure reducing valve is working properly. If you suspect that a valve is a source of your problem, then replace it with another type and examine the rest of the machine for potential causes of the issue. If none of these solutions work for you and your pool is still leaking, then it could be time to consider replacing the entire unit.
