Why do I lose hot water pressure when I flush the toilet?

When the toilet flushes, cold water is diverted to refill the tank, which causes a pressure drop in the cold water line. It takes a pressure balancing valve a couple of seconds to adjust, during which time the water may turn very hot because the valve isn’t getting all the cold water it needs.

Does toilet affect hot water heater?

Probably, the toilet supply is located close to the water heater, and when the toilet fill opens up, it causes a drop in pressure on the cold line feeding the water heater.

Can a hot water heater cause high water pressure?

The most common source of high water pressure is actually the municipal water supplier. It’s also possible that you have a faulty expansion tank on your water heater. At the end of the day, the cause of high water pressure is usually something outside of your control.

What causes hot water to build up pressure?

Without proper maintenance, your water heater can go from heating up your water to exploding under increased pressure. In short, when the temperature or pressure of the water heater gets too high, the valve opens, and releases water that’s causing the increase in pressure.

How do you adjust a pressure reducing valve?

Loosen the lock nut on the pressure reducing valve with a wrench and back it off by unscrewing it. Fit a socket wrench over the adjustment nut on the top of the valve. Turn the nut counterclockwise to reduce the pressure downstream from the valve and clockwise to increase it.

Why is my toilet bowl water hot?

The mixing valve installed on toilets to prevent condensation causes water to be lukewarm. During a normal flush, only a little hot water comes through the mixing valve, but if there’s a hot water leak it will overpower the cold, steadily raises the temperature, so you eventually have a hot tank with a warm flush.
