I had an Watts N35B [Year 1996] pressure regulator that was CHIRPING, THROBBING so I replaced it with the N45B.The N45 is an 'EXACT' drop in replacement for the the older N35, See pictures.WARNING! The new unit should have O-RINGS on both fittings (ends), mine only had one, so I used an old O-Ring from the old unit.BRASS: being all Brass, things were not stuck and job only took 10 minutes.BRASS: being brass, you don't want to OVER TIGHTEN the soft BRASS nuts.YOU can do it..... if you read everything above... :)
