In response to Re: circulating pump
: The bearing assembly on my Bell and Gossett circulating assemly is leaking from a small machined hole on the underside of the unit. My plumber has recommended I replace it with a cartridge unit made by Tago (spelling may not be correct). My heater is a Weil Mclain with a 140,000 BTU input and a 112,000 BTU output and is about 20 years old. My home is only about 1500 sq ft with 3 bedrooms. Do you recommend replacing the bearing assembly with a B&G bearing assembly or replacing the entire unit with the Tago cartridge unit. In addition, after my plumber replaced a pressure release value on my unit, he closed the fill value which is located between the heater and a B&G pressure reducing value. Is this correct or should the fill value be left open and the pressure reducing value be adjusted accordingly (10-15 lbs)? Thanks in advance for all replies.

Have you looked at the bearing assembly? Maybe
you just need to replace the mechanical seal and
not the whole bearing assembly. The most common
reason why they leak is due to a damaged seal.
