Background: Me- home owner, not a plumber and have not done plumbing work, and do not intend to, but I have a problem that is puzzling the installers.
House: 1993 construction, copper pipes, recirculating system on hot water, with no pump involved (convection I guess). Two 80 gallon water heaters in series, 3/4 pipe on outputs, but the return for the recirculation looks to be 1/2 pipe. I do not see a check valve on the recirculating return pipe.
Water heaters are less than 3 years old, AO Smith. Water softner in place, also about 3 years old.
Problem. Every few weeks the shower heads in the main bathroom are obstructed by greenish white particles, and have to be removed and cleaned. Interestingly only one other faucet in the house has a significant issue, the other showers and faucets have not had to be removed or cleaned. Plumber that installed the water heaters suggested a problem with the softener, figuring that it is regenerating over night and the first shower used in the am is getting the debris. Softener people have been here twice, water tests ok, they have no suggestions.
I would be interested in any suggestions on how to figure this problem out. I am wondering if there is a problem with the recirculation system, causing corrosion somewhere in the pipe system, leading to the problem.
Thanks for any suggestions!
