Water heater drain valve leak in San Jose, CA

Issue description:

Causes of safety valve breakage

With constant high pressure, the spring inside weakens, the part needs to be replaced

If the valve on the boiler drips constantly, regardless of the time of day and the intensity of water use in the house, there is a high probability that the product is faulty. There may be many prerequisites for this.

Factory defect.

As a rule, these are weak springs and leaking cylinders. Such products will work even with a working head. Faced with such a nuisance is the fact that trying to save money and buying cheap Chinese fakes.


Occurs when the tank is not cleaned correctly or because of poor water quality. The essence of the breakdown is that after compression, the spring cannot be released, since an obstacle from solid particles forms on its way. With such a malfunction, the product will leak even when the device is turned off and the tap is closed.

High pressure of the system.

This is not uncommon on the last floors of high-rise buildings with an upper water supply. Since the head is kept at a constantly high level, the valve will flow continuously, regardless of the time of day.

Mechanical damage.

Occurs during transportation or during installation. You can also damage the internal parts during cleaning - deformation of the spring, rupture of gaskets. When falling, a gap appears at the entry point of the nozzle into the boiler body.

Leakage of the storage tank.

In such cases, water is observed outside the product, but it may seem that a valve on the water heater is leaking. Leakage is caused by corrosion or a split seam.

Leaking upper part.

Poor connection. This is one of the most common causes of dripping on the valve. In most cases, this is due to a hardened gasket under the nut or an insufficient amount of FUM tape.

Wear of the springs.

Over time, they lose their elasticity and begin to compress even with a slight pressure. Nothing will help here. All that remains is to put on a temporary drain and go to the store for a new valve.

Water heater drain valve leak

Problem solution:

First you need to make sure that the leakage is caused by a non-return valve. It is enough to check whether its case is dry or not. If there is no moisture on it, then you need to start disassembling. This event can be timed to clean the TENA and the tank from scale. In any case, efforts will not be wasted.

Dismantling should be carried out in the following sequence:

Shut off the water. If a straight-through valve is installed in front of the mixer, it is better to turn it so as not to turn off the entire apartment.

Disconnect the device from electricity. Remove the cover, disconnect the wires from the terminals.

Unscrew the underwater pipes from the boiler. Remove the ball valve and the safety valve.

Screw the flexible hoses to the connections, the water will flow in the right direction. Br> If there is a pressure gauge, check the working water pressure. Ideally, it should be 1.5-2 atm.

While the liquid is draining, remove the remains of the FUM tape and inspect the parts for cracks and dents.

Clean the tank and TEN from lime scale and scale. Rinse the inside of the container with a shower head. If you need help with water heater repair near me, call us right now!
