Hello all. I simply need some clarification as I just cannot find any answers online.
Apparently newer water heaters have heat traps (nipples?) which prevent recirculating pumps from mounting and/or operating with the water heater. I am confused as to whether this is because (A.) the pump will not physically mount directly onto the water heater (in which case a simple pipe extension would solve the issue) OR (B.) if it's due to the fact that the heat trap valve/flapper needs much more pressure to open (i.e. a faucet opening) than the pump can provide (very low PSI/GPM compared to the faucet).
It seems that heat traps are mandated oral water heaters at this point, so it is hard for me to understand why recirculation pumps may not be compatible. Any clarification on the matter would be very helpful. Thank you!
