water pressure

I'm negotiating a contract for a home purchase. This is a three-floor townhouse with a basement. During the inspection, every fixture--3.5 BA and kitchen--showed great pressure and volume, with the exception of the master shower. (The master bath tub and sinks, which are adjacent to the shower...

I live in an older house which has undergone lots of cobbled plumbing. The entry pipe to the house is 1/2" galvanized. Before going to the upstairs bathroom it changes to 3/4" pvc and then back to 1/2" copper. Because the Pvc is larger does this have any effect on water pressure. Should this be...

Just moved into new apartment, 2nd floor of a 3 story brownstone (3 single bedroom apartments total). Water pressure in bathroom sink is terrible. Approx. 20% flow on both hot and cold. Bathroom shower has good pressure and toilet fills correctly. Pressure has no change when running hot...

I live in a 2-story, 1.5 bath home which a 6-8 months ago started having a strange symptom of intermittent low water pressure. The Symptom Randomly, the whole house will have very low water pressure. The flow is noticeably slow, less than half the normal flow rate. Both the hot and cold water...

I started with 3/4 inch pex feed to 1/2 inch pex to fixtures. I noticed the pex fitting ( elbows , Ts, etc.) have an inside diameter of 1/2 inch for the 3/4 inch fittings and 1/4 inch diameter for 1/2 fittings . Does this reduced diameter in the pex fittings reduce the flow of water ?? I...

i have installed a fountain submersible pump in my pond to use to water my garden / flowers. The discharge is 1 1/4 ". I want to reduce it to 1/2 " to connect to a water hose. Does it make any difference to resulting water pressure if i reduce in one stage or in several stages ?

Home: Single Family, built in 1938 Situation: Water pressure averages 62 psi with a temporary 11 psi drop (toilet flush, fully open faucet) Problem: Kitchen (1st floor), Shower and sink (2nd floor) water doesn't flow with the "aggressiveness" I've experienced in other homes. Observation...

Hello, first post. Thanks for the help. I've recently finished my basement and had a professional plumber do most of the plumbing work for the bathroom. It took me years to complete the job so the plumbing work was done a long time ago. Anyway, everything is working pretty well except one...

Our pressure switch turns on and off consistently when water is running.. we replaced pressure switch and did not fix it....so i read our pressure tank should has 2 psi...so i press in the shreader valve on the tank...no air comes out or water...so we try to put air into the tank and it wont go...

Hey, guys. The water pressure in my townhouse has always been pretty weak. My neighbors do not have the same issue. Recently, I've been suspecting this...umm...thing. Where the water enters my house, this device sits between two gate valves. What is it? Do I need it? If it does have something...

Hi all, new to the site. I recently had to replace my entire septic line. While they were doing the work, they cracked into my supply line to the house and damaged some of the internal plumbing. I got water in immediately and figured I deal with the rest when I had time. My water comes from...

the water pressure is pretty low in my house. not so low that i can't use something but low enough to annoy me. the main water valve in the yard is wide opened and all valves in the house are wide open. i don't know how big of a pipe i have leading into the house. I have already put the...

*Disclaimer - I have no practical plumbing experience, just common sense (i think) So we moved into a brand new home a few weeks ago, which is plumbed trunk & branch style using 3/4 and 1/2 PEX. We moved about a mile from our old home which had GREAT pressure and volume, so the city supply is...

I have lost hot water pressure in my house. The cold water pressure is fine. Our water heater is electric. The valve on the hot water line is wide open. Thank you for your suggestions and assistance.

Just moved in. I have an odd problem, only in my kitchen sink. When I turn on the water hot/cold it takes a few turns for the water to come out, and when it comes out like the valve is all open (Full flow 100%) then I can back it back to get the proper flow. It' a hastle, having to wacth out...

All - i'm hoping some veterans can help me understand whether i have a problem. my house is on a well water system. the water pressure fluctuates with use. for instance, when i open a tap and run cold water, i can see the water flow fluctuate. the water flow doesn't go down to zero, but the...

I replaced the T&P valve on my gas water heater because it was stuck open and running hot water down the drain constantly. The new valve still opens too often and my bathtub faucet is leaking now(it didn't leak before I replaced the T&P valve and it stops when I turn a faucet on or flush the...

Please help! I just had the RO serviceman out and he told me it was not the RO water pressure going to the fridge (the RO is coming out of the wall behind the fridge at 30psi), so it is a fridge problem. (Can't afford ANOTHER service call right now -- but we really need some ice in AZ!) No...
