Too small.

We have a Noritz NRCR111 which was exceeding 140psi pressure when using recirculator. We installed ST-1 on hot recirculating line, as Noritz recommended, which didn't help; we then installed ST-5 which solved the problem! I'm unclear when ST-1 would help with thermal expansion. Go big!

NOTE: This is for Tankless or POU water heater-

It was my fault for not reading the submittal sheet- but it should be noted in the product description.
