Will this work with a Rheem PROE50 M2 RH95 water heater that has heat traps?

Hello, a. Unfortunately, we don't have a list of hot water heaters that our unit is compatible or incompatible with. The pump works with most standard water heaters. You may need to review your hot water heater manual to find out if it has heat traps installed from the factory. If you do you may have to remove them for optimal performance. We recommend checking with the manufacturer first to see if they recommend it and to ensure that this will not void your warranty. If you cannot remove them and they prevent the pump from proper circulation, we suggest trying 2 sensor valves at the furthest location from the hot water heater as this will help increase the flow. This normally works with defeating those heat traps.
