water hammer

I have had a Watts 500800 recirculation pump installed for a few years without issue. The pump is on the water heater in the garage and the sensor valve is installed at the kitchen faucet about 40 feet away on the first floor. Within the last 6 months or so, I have noticed a water hammer...

Hi all, I have been hearing an occasional water hammer sound after the master bathroom faucets or shower have been used. We get slight sputter at the beginning of turning on the faucet making me thing there's a tiny bit of air in the system somehow. I hear it in the walls and the sound occurs...

I replaced the fill solenoid valves on our washing machine and while I was at it decided to replace the old rubber hose with the newer style with stainless steel mesh on the outside to reinforce it and prevent it from bursting. The old hoses were probably around twenty years old or more. The...

Hello, We had our gas water heater replaced after leak. Due to new code, the new water heater has an expansion tank. Otherwise same exact brand as we had before. Since this is in place, we have been hearing pop noises in the house. It happens when run is running or not. Noises frequency...

Wondering if what I'm dealing with is water hammer, and what a solution would be. Happens as my washer is filling at the beginning of wash cycle, and again when it fills to rinse. Only way to stop it, is to stop the washer from filling and run upstairs to turn on the water in the bathtub. If it...

Hi, I managed to push two 15mm pex pipes through the underfloor space of a second floor. They go (on a straight run between two parallel joists) from a hole in the floorboard (18mm thick) under an existing radiator to another hole in the contiguous room's floorboard, ready to attach a new...

I’m hearing what sounds like a water hammer in the pipes near my hot water heater(tank). With no water running, it knocks about every few seconds to a few minutes. I turned off the water heater at the breaker, electric only. Waited a day and used up what hot water was left. The knocking...

Does anyone know of a 3/4 inch water hammer arrestor for pex, or an easy way to do it? (Without using push to connect). Backstory: I replaced a leaking copper pipe with a pex line (3/4 inch) , it runs to a copper pipe which goes to an outdoor sprinkler system. When the system shuts off I...

I have an outdoor faucet timer (https://www.amazon.com/Orbit-62061Z-Single-Programmable-1-Valve/dp/B004INGS8S) that goes to a drip system for some plants outdoors. Every time it turns on, I can hear a loud bang inside my house. I tried getting a water hammer arrestor, and it helped, but it's...

Hi, first time poster here! I've been having some issues with the water supply in my home. It started with my refrigerator losing water pressure when using the water dispenser right after I replaced the water filter. Then gradually making 'water hammer' noises when using the water dispenser or...

Hoping some experts can chime in and help out. Both my plumber and I are stumped. Here's what we did: 1. Replaced two 50 gallon water heaters in the attic with a 75 gallon in the garage (18" off the floor). The 75 gallon was directly below one of the old 50's in the attic, and we ran...

I've never had an issue with water hammer in my house until a couple months ago. The fill valve on our newer LG washer went bad. Because we had the extended warranty I just called the company and they sent a tech. He confirmed it was the fill valve and replaced it the next day. Ever since...
