We are trying to determine the cause of a thumping

***** *****. We are trying to determine the cause of a thumping noise we are getting that seems to be coming from the area of the PRV and is getting progressively worse every day.JA: Thanks. Can you give me any more details about your issue?Customer: We purchased the home in mid Dec. and it only made this noise 1-3 times a day for less than 30 seconds each time. Now it is hours on end. If you shut off the main to the house AND the main to the irrigation system, both are less than a foot past the PRV the noise stops, but opening one or the other it starts again. The only other way we can temporarily stop it is by turning on any faucet or flushing a toilet, but it starts again 30 seconds to 2 minutes after you shut the water off again.JA: OK got it. Last thing — Plumbers generally expect a deposit of about $18 to help with your type of question (you only pay if satisfied). Now I'm going to take you to a page to place a secure deposit with JustAnswer. Don't worry, this chat is saved. After that, we will finish helping you.

We just finished a bathroom job. The shower has two shower

We just finished a bathroom job. The shower has two shower heads. The water pipes both hot and cold are half inch copper. I used a tee to split them and send cold and hot water to each shower head. Sometimes, especially when you turn one of the units off while other is still on you get terrible vibration in the pipes. This is fixed by cranking the valve all the way hot. I realize you are going need more info so please just tell me what info you need.

Im remodeling my bathroom and I would like to use PEX to run

Im remodeling my bathroom and I would like to use PEX to run my supply lines though I have a couple of questions.I looked at 1/2 inch PEX and the line and the connectors look like they have a smaller inside diameter than the 1/2 copper tubing. The existing tub, shower, and sink all have good flow and pressure. All things being the same (length of run and turns) would replacing 1/2 copper with 1/2 PEX result in a noticeable change in flow/pressure from the tub, shower, or sink?Would PEX require a hammer arrest?Last question: The shower, tub, and sink all have their own lines branching off the 3/4 however due to obstructions in the way I can only get to within about 1 1/2 feet from the 3/4 so I will have to cut the 1/2 copper lines and attach the PEX. The gentleman at the hardware store told me that I could use sharkbites to connect the copper to PEX even behind finished walls and floors. I would like to ask a professional in the industry though what their take is on using sharkbites behind finished walls or floors.

I have a residential well servicing my home. Every time the

I have a residential well servicing my home. Every time the submersible pump kicks on, I get a large water hammer just downstream of the pressure tank that shakes the pipes and even sometimes kicks off the pressure switch and I lose all pressure. The tank is set at 40-60 psi. The pipe is 1" pvc just after the tank. How can I stop the water hammer and keep the pressure switch from kicking off?

I have a LG Model WM3570HVA Washing machine. The pipes knock

I have a LG Model WM3570HVA Washing machine. The pipes knock when in use. My older machine had no problem. I had a thermal expansion tank put on my water heater and thought this would help but it appears to not help. Is there an issue with this model due to its Turbo setting of pulsing water?

Currently live in Salt Lake City and the house was built in

Currently live in Salt Lake City and the house was built in 1953. We change the main water line to HDPE pipe in 2009. The contractor did not setup a water regulator. The current psi is 100 psi according to garden hose line. My question is, I am planningto put a water regulator in but it would have to be underground. Can a regulator setup underground and outside specially for winter state like Utah?

3 months ago, the supply line on our master bathroom toilet

Hi, 3 months ago, the supply line on our master bathroom toilet broke and began gushing water onto the bathroom floor. The plumber who came out replaced the supply line and checked our water pressure regulator, (it had been dripping for at least a fewmonths beforehand & we kept meaning to get it checked but didn't). He said the regulator was bad & he replaced it. Here's the problem: Since then, we keep hearing completely new & unnerving noises from the pipes in our walls. The noises sort of sound likesomeone is taking a wrench and tapping a single time on the pipes, sometimes very softly & sometimes significantly more loudly. It happens roughly 12-20 times per day, throughout the day and the night and whether the water is currently in use or not. The soundsvary in volume from kind of soft and quiet to moderately loud and have been heard in various rooms & both bathrooms, but especially in the room in which a tremendous amount of loud screeching noises were heard coming from within the walls while the plumberwas doing his work immediately outside with the regulator (he had to add some additional pipe b/c the previous regulator had been fitted with 2 different size pipes or something.) When he was all done, he showed us with his meter that the water pressure wascorrect. Currently, the new pressure regulator is NOT dripping or leaking any water. By the way, last autumn (2014), city workers were doing some work right outside our house in the street, I think possibly in the sewer & while they were outside, I heard crazynoises coming from the drains in the kitchen sink and the clothes washing machine. I have no idea what they were doing & at one point, one of them did ring the doorbell, but I was indisposed and by the time I got to the door, the public works truck was alreadydriving away. I mention all that because since then we've had more plumbing issues than we've had in the past 10 years. That December, a supply line valve to our water heater broke ,(our water heater is inside the house), causing a big leak and water damage& at the same time the hall bathroom toilet kept spontaneously refilling itself, requiring a new flapper and fill valve. And then 6 months later, the supply line to the other toilet busted and the pressure regulator needed to be changed. I'm wondering if thewater pressure from the street is too high and/or if the pressure within the house is too high. Do you have any idea as to what could be causing these noises and if they could be related to this recent work (our plumber and/or the city workers) and if thenoises could be indicative of a serious problem? Your expertise and insight are greatly appreciated!

I'm having a thumping sound when water runs. Seems to be related to the pressure regulator. If I partially cut off the main water supply, the knocking stops. It's a slow thump (I don't think it's water hammer).
