noisy water pump

[zac451]

Anybody know how to quiet down my water pump? When the pump comes on it rattles the plumbing (really loud), Thor told me they put in a cheaper pump and to fix it I would have to put in a better quality pump. Any ideas or should I just replace the pump with a better one.

Thanks everyone for you ideas, for what I paid for this 2013 Freedom Elite, I don't want to contribute any more then I Have too...$$$$. I will try your ideas first and let you know what works....Zac451
By the way, I was just at Thor to get some repairs done on my slide out. Great people to work with. The Mechanics are great and the service Reps will do everything they can to make you happy.
Also met a great Guy (Aikenracer)From SC that was there for some repairs on his Bigggg Pusher. It was nice to have someone to talk to while I was waiting for my repairs to be done.
Thanks again for the replies.

I installed a 2 gallon accumulator and it really makes the RV water pressure more like a house. Water pressure is more consistent, especially beneficial when taking a shower. The pump cycles nicely, a much more friendly sound than the on/off groaning all the time.

Total investment was between $40 & $50. If you look close, the brass elbow to the left has the flex hose attached from behind. I also added a ball valve seen in the foreground, for an emergency just in case I had a catestrphic failure of some sort and needed to quickly cut off the supply from the fresh water tank. 5 years so far and the setup is still working great.

Exactly....the pump discharge line should be a flex hose vs rigid pipe.
Also secure the piping so that is doesn't move around banging on inside of cabinet.

Pump should be mounted on rubber feet....if loose or too tight it will be nosier.

No need to replace your pump. You only need to isolate the pump vibration from the RV plumbing. Install a stainless steel braided intermediate piece of plumbing like shown here, making a world of difference. Also make sure your pump is mounted with rubber grommets.

Sold in all home improvement centers in lengths from 6" to numerous feet. Cost is very affordable.

Before doing that...and this comes from experience...check at the inlet of the pump to see if you have a screen/filter gizmo, coming off the line>>> to the pump. If so, remove and clean, then see if that makes a difference. If not..then yeah, a pump change. You do it yourself and the pump is along about $75 or so. Shure-Flow.
