hot water

My contractor installed these CPVC pipes shown in the photo for a double vanity. When you turn on the hot water on either sink (hot water is on the left on both sinks), there is knocking that starts once the water gets hot and it doesn't stop until about 15 seconds after turning off the water...

We have an 80 gallon water heater. Downstairs shower head has regular shower head, upstairs one has a fast flow shower head. If one person showered in each for average 10 minutes, is it normal 5 hours later to have no hot water for it to "build up again"? We have checked the circuit breaker on...

Hello, Yesterday our hot water stopped working. I think I've been able to trace it to the circulator pump but not 100% sure. So no hot water coming out of the holding tank. Pipe is ice cold. All pipes coming into and out of tank are cold. Follow pipe from tank to circulator and boiler and it is...

I'm having a problem with my moen posi temp shower valve. So I have a tankless water heater, im in the process of fixing the elements right now so i can't actually test for hot water, but I can turn the water back on. I replaced the shower valve as it was giving me issues. Here's the problem...

Hey guys, my dad is in need of some help. He's a retired carpenter who was really excited to do his own shower, but now is running into some issues after everything has been put together. When using the shower, the handle can't be turned more than a quarter turn, and as a result we never get...

Hi there, Recently bought a bidet that comes with a hot water connection, but neither the 3/8 or 1/2 T-Adapter for the bidet is compatible with the sink's hot water valve. I thought the valve was 7/16, but I bought a 7/16 Female x 1/2 MIP Reducing Adapter and it doesn't fit, either. I've been...

I am a new homeowner and am learning the ropes. We have a tankless coil water heater on our oil furnace. The hot water pressure in the entire house leaves a lot to be desired and has gotten worse as of late. I suspect the coils need to be cleaned and I'll get to that as soon as I can. However...

Hello, can you please help me? A little over a year now, my husband and I moved into an older, tiny home. There's well water that's freezing all year long, pumped into the house via a water pump in the shop right beside the house. There's a tankless water heater in the front (not far from the...

Hi there, We have a standard gravitational system at home and a Salamander pump CT force 30pt is part of the hot water system for the 2nd floor. For the last three months, the pump didn't work well and wasn't starting to generate pressure each time we opened the taps/shower handle. At the...

I manage a five story 16 unit building in New York City, and for months now, had resident reports of hot water that is only lukewarm much of the time, or takes very long to get hot. Even in off-peak (early hours ~ 4 AM) where there should be plenty of stored hot water, the water is initially...

In a conventional system, the standard arrangement is to have a gate valve on the (typically 28mm) cold feed pipe from cistern to cylinder. Out of curiosity, I was wondering why you won't find it on the hw pipe (typically 22mm) going out of the cylinder instead. Of course, positioned after the...

Hello all and thank you in advance for the help. My bathtub faucet has been either providing lukewarm water or running low on hot water fairly quickly the last month or so. I think it was always cooler temperatures than other fixtures in the house, but it has become a problem recently. All...

My family purchased a new home a few years ago. This issue has always been present, but I'm finally getting around to figuring out the issue. Our water heater is in our basement and our bathtubs are on the second floor (2 floors up). If we try to fill the tubs with hot water quickly, the...

Hoping someone can help troubleshoot an odd situation that I haven't been able to answer via many Google searches! The hot water in our primary kitchen sink has begun working inconsistently. It may provide hot water immediately and then get cold and take many many minutes to get hot again. Or...

Hi everyone, I live on the 3rd floor of a 6-floor building. I completed a gut renovation years ago and installed a shower and washer/dryer in a former bedroom, connecting the plumbing to the adjacent bathroom. It takes a long time for the water to heat up in all of the bathrooms on this line...

Tub faucet is either giving very hot can't stand in it type almost scalding water or very cold icy. No nice warm shower. No happy medium temp. Just had cartridges replaced as it was not fully shutting off (constant drop). That drip is now fixed, but now it won't get mix of water. Seems only...
