No hot water in the recirc lines

No hot water in the recirc lines

by Mick

We can tell if there is a problem with the anti backflow valve in our recirc line when we don't get hot water in a short time. The minerals in our water stick the valve open and it doesn't contain the hot water. We keep an extra valve on hand and change it out and clean the faulty one in CLR. Our other problem though is the pump just quits - unplug it and it usually starts up right away. Cant figure out why unplugging it and plugging it back in fixes the problem. Any ideas?
