Hi: I have a hot water recirc line with insulation feeding back to the cold input on the h/w tank. Just before the cold connection I have installed a brass flap style check valve in a horizontal position.
The recirc, without pump (convection) works well.
I have had problems with the check valve sticking.
When this happens I get cold showers when the cold short circuits.
Last time, about 6 months ago, I took the valve all apart, the pivot pin, flapper and made sure they were all clean and smooth. Heck of a job to get the pin out!
It has started to stick again as noticed by cold showers.
My water is very pure, rain water that is ozonated, passed through a carbon filter and finally through a whole house R.O.
I know I cant lubricate it, any help appreciated.
