When water comes in it makes the water lines shake. They say it is the inlet vale. Is there any way I can test it to be sure. thank you
2 things can cause the unit water lines to chatter. The water pressure being too low or the screens on the water valve being clogged. The other thing is the water valve being faulty. Check the water pressure to the unit to make sure that it is good and make sure that the screens on the water valve are clean. If these check ok then you will need to replace the water valve WH13X10023.
