Low water pressure in water heater in San Jose, CA

Issue description:

Low water pressure in the water heater. Is the pressure normal in the cold water tap, but low pressure with hot water from the water heater? There can be several reasons for this:

The pressure reducer on the water heater is incorrectly adjusted or is out of order.

The pressure reducer is incorrectly adjusted, and the pressure is low. The boiler device is designed in such a way that the inlet pressure is the same at the outlet. It is necessary to diagnose the reducer, and if it is functionally possible to change the pressure on the reducer, then it is necessary to do it.

The back pressure valve is out of order or clogged.

Sometimes, the valve is clogged with debris that flies through the pipes to the boiler. In this case, it is necessary to remove the check valve, check it for operability and the presence of debris in it.

The filter "mesh" on the mixer is clogged.

The filter on the mixers is clogged with fine debris. It is necessary to unscrew, move, and check the filter for the presence of debris, perhaps this is the main problem.

The tap on the water heater does not open until the end.

Sometimes the tap installed on the cold water pipe of the boiler fails and does not open completely. This serves as a kind of pressure limiter. Here the problem will be solved by replacing the tap.
