I always say it; noisy (rattles and roars or loud bangs and hard knocks), leaky, or blocked up (and clogged up) plumbing are consistently the most common household issues. Here are a couple of solutions for two of our WYSK readers who are struggling with the kind of troublesome plumbing problems many of us can relate to…
“We remodeled the downstairs of a bi-level home adding bedrooms, a kitchen and enlarging a bathroom adding a shower. We have an air chamber or something on the sink in the new kitchen as a vent. The builder hand-built a manifold so we could get to the shut off valves. Now we hear both a machine gun like banging and a slow rhythmic noise in 2 or 3 other places especially in the mornings when the water is first used. We have a well and the pressure is 40 lbs at max. All of the pipes and valves are CPVC. No one seems to know what to do. Help.” – WYSK Reader Linda
NV: Hey there! If this noise started after the renovation and the new manifold was installed, I would go after the builder/plumber that did the work.
For those who aren’t familiar, a plumbing manifold is a kind of command center of water shut-off valves to the entire house. It’s a really helpful system that can easily shut down water to any given fixture/appliance when needed, making it easier for work to be done, plus diminishes risks of leaks at joints and fittings because there are less of them.
As for the air gap at the sink, from what you’re describing, that’s there for the dishwasher to drain properly.
My guess is, from when the work was done and lines opened, air got trapped somewhere in your pipes. Have you tried bleeding the lines in the entire house?
Here’s how to do that as covered in one of my previous Fix-It Friday columns, but in your case, be sure all of the shut-offs at your manifold are in the open position.
Also, try to find exactly where the noise is coming from…this could reveal what’s specifically causing the problem behind the ceiling or wall.
If these approaches don’t do the trick, like I first stated, go after the company that did the work in the first place, and make them accountable for your new noisy plumbing!
“Hello. When the hot water faucet is turned on the pipe knocks and not always do I get water. How do I fix this? The cold works fine and no noise occurs. All other bathrooms and sinks work fine. Thanks.” – WYSK Reader M.
NV: Hello, M! Sounds to me like there’s a problem with the hot water valve in that particular faucet. To test this theory, I would shut off the HOT water at the shut-off valve under the sink, then disconnect the supply line from the shut-off to the faucet.
With the supply line now disconnected, gently turn the shut-off on to test that the hot water shoots out from the valve with no restriction. Do it fast and prepare to get wet! (Place a bucket or low receptacle underneath to catch the water).
If this water is flowing, it’s clearly the hot water valve of your faucet that needs to be repaired/replaced. This fix will depend on what kind of faucet you have. If you’re up to the challenge, send photos of your faucet and I’ll help guide you through. If not, armed with the knowledge of already knowing what the problem is, call in a pro!
