Circulator pump I have purchased 4of these pumps in the last few years and have been 100% satisfied with them. They are not inexpensive but I think you get what you pay for.
The service I receive from Pex has been problem free.

Ask a Question Integral Check Valve, i.e. built-in (but easily removable) check valve - to allow water to move only in one direction.
