Vibrating hot and cold lines

TeeNyTaBBer

When we aren’t hooked to water - obviously - and have our tank full and the pump on - it’s really noisy. Upon investigation it’s the lines vibrating and causing the racket inside the holes cut in the wood. Anyone deal with this?

@TeeNyTaBBer, that is a common situation caused by the water pulsating from the water pump.  You can try mitigating it by putting some foam water pipe insulation (available from a hardware or home improvement store) around the vibrating water lines.  I found that my shower water lines hidden behind the shower wall were doing that.  I put some foam insulation around them and it solved the problem.  I also have had the vibration issue at my water pump and connected water lines, so I put some padding behind the pump.  That also helped, but I need to add some foam insulation to the water lines as well.

Hi, Would an RV water accumulator help smooth out the flow?

Absolutely.  I installed one in the 2009 T@B and it made a big difference because of the older style pump.  Our 2023 Ultimate Toys CS pulsation was much less noticeable but the accumulator still is an improvement most evident at low flows.

Sooo UPDATE to my problem…. We discovered that both hoses attached to the water pump should be flexible… only one was so we changed it and that seems to have made it much quieter overall… for the few times we don’t have a city water hookup 👍🏻

I also found that the original pump in my 2015 was quite a bit noisier than the one I replaced it with when it died after nine years

Jenn Grover gave a great tip on one of her videos.  We use it and it works every time.  With the pump on and the sink water tap running, hold the toilet flushing button till the pulsing stops.  Good luck.
