“My oil fueled boiler was often leaking at the pressure relief valve and the air vents... the logical culprit was the intake valve which we’ve had for ten years. It was providing inconsistent pressure to the baseboard hearing system. Pulled the old one out along with the three inch nipple below it and replaced it with this new one. Works like a charm after a quick adjustment to the pressure screw!”
“What’s to not like? Easy replacement, only took about ten minutes. Took longer to relieve pressure on the system than to replace the part. Count on about an hour and some water on the floor.”
