A while ago I wrote about a problem with my water heater-no hot water when I turned on faucet. With the help of the forum I decided to change the check valve.
My unit is a 2001 Winnebago Itasca Horizon 36 ft. I found a broken check valve on the cold water side of the heater. Behind the water heater is a terrible location to access, I followed the line and installed a new check valve about six feet away, nothing between the heater and check valve (in the water compartment) easy access. I now have hot and cold water on demand.
#1 Now every time I flush the toilet there is a noise Sounds like the water pump running for a few seconds or a vibration in the water lines.
I have checked for vibration and found none, the water pump is not on at this time. I have found when I switch the system to water heater bypass- the noise disappears
. I am wondering if there is such a thing as turbulance or air in the water heater causing this noise.
#2 When I am using the motor home water pump the pump cycles, once every 10 minutes. No evidence of a leak.
ANY IDEAS ????
