I'm running a recirculation pump and a thermal bypass valve. Can I use more than bypass
Valve in the same system?

Mass P. thanks for reply.The pump in question is a GrundFos type UP15-10BU. The application for that
Pump is outlet side of water heater w/ shaft horizontal and a thermal bypass valve at the farthest most
Sink in the system. But the system was originally designed to be a gravity feed, unfortunately the last
Plumbing contractor wasn't up on this system and ran the return line into the basement before reaching
The HW heater no mas gravity feed. This pump was retrofitted so it pulled water from the upstairs HW
System . IT works great but my system has a major branch that is not getting recirculated. I want to add
A second pump on the second water heater on the outlet side using the thermal bypass valve supplied w/the
Kit.which requires no return line. It basically lets the cooled HW bleed into the cold side until a temp
Sensor stops it when it senses HW at the valve.I'd like to put 2 valves in the troubled area to eliminate
All temp fluxuations in the ladys shower area.
