Hi, Is plastic or copper tubing best for the refrigerator water line --or should I use a braided steel one? Our refrigerator has a plastic water line coming up from the floor and I want to make sure this is the right one -- I keep reading conflicting things. Thanks.

Hi, Can someone explain to me how the thermal expansion bypass on a water pressure regulator works? Like, after the water heater shuts off, is the regulator supposed to readjust the pressure back down or what? I can't tell if we need to get an expansion tank. The pressure went up to 95...

Yeah, there's some noise in the upstairs bathroom. It's not that bad, apparently only I can hear it (I'm sensitive). Definitely helps if people didn't close the faucets so fast. Not enough room under the sink to put water hammer arrestors. Also slight tapping noise in the downstairs bathroom...

The street pressure, or the main water pressure from the street, is 80 psi. Whether that is consistent or not is not something the water company seems to guarantee. I'm pretty sure the thermal bypass works because I checked the pressure when the dishwasher (thus the water heater) was running...

The PRV has a thermal expansion bypass, which explains why the static pressure stayed around 60 when the water heater was running. Still doesn't explain the spikes past 75, which is the max of the PRV. I guess I'll call around for estimates at this point.

Hi everyone, I'm new to this forum, but I was hoping to get some advice before I call a professional. We have a Watts N35B pressure regulator with a range of 25-75 psi, set to a standard of 50. I measured the pressure (with a watts gauge) at the front hose and it was 60 psi (give or take a...
