Hello. My name is Tan.

Locate the water pump look for a filter before the pump inline on water supply to pump.

Some have a strainer type filter that will clog. Check that filter. Post back if no filter or that doesn't resolve the issue. We can then proceed.

Ok we need to check the lines at the water heater. Do you have any valves on the water heater lines. This will be the hard plastic lines?

Ok we need to disconnect the water line at the water heater. Look at the inlet and outlet of the water heater. Do you see any blockage? If you can tell which is in and out disconnect the line from the outlet and watch water flow when water is turned on.

Do you have good water flow?

Ok will check

OK

I will have to bring out a heat gun tomorrow I will check the flow into tank.
Expert:  Tan replied 5 months ago.

Ok I think we could have an issue with the water heater. These water heaters have an aluminum tank and can corrode real bad and cause a restriction.

Keep me posted.
