Pressure Reducing Valve
Please, if anyone can help with info it's greatly appreciated. I've noticed recently while running washing machine and irrigation or any combination of water in the house I'm getting some weird sounds knocking. Mostly from where the pressure reducing valve is located.
I had a plumber come check it out yesterday...he gave me a quote of $675 to replace it, saying that it's not as simple as just unscrewing the bolts and and re-attaching. He says he has to cut the pipe and re-solder them. I checked the whole sale price of these and they look like they can average between $75 and $150. Which means I'm probably paying about $450 in labor.
I can't find any info on this item unless its somehow connected to a water heater. Seems like they go hand in hand. And he did ask questions about the water heater but never mentioned it might need to be replaced. Is he going to come in and tell me I need a new water heater?? This is my fear and I don't mind paying buy I hate not knowing whats up.
Any info would be great. Thanks in advance.
