I have a check valve on the input side of the water heater. It decided to quit and is restricting the forward water flow. I took it out today and it has a plastic center plunger with a brass case. The plastic plunger is broken.
I understand it's purpose. The purpose is to keep expanding hot water from backing up into the cold water system. I do not mind that back up as I have an accumulator to take up that slack but I'm thinking I'll probably be irritated if I turn on the cold water and initially find warm water coming out.
I looked on McMaster-Carr for an appropriate replacement. If I order it tomorrow I know they will deliver it the next day if UPS can figure out how to get the 35 miles to my house from McMaster in Chicago. I'm trying to decide which one to get and also decide if I really need it in the first place.
I also see some plastic ball check valves. I'm wondering it that might be a better idea for this application.
