For winterizing purposes, I thought installing a valve with tubing between the fresh water tank and the pump would be a convenient add on.
Is that what it's for? My system has always had a valve between the fresh water tank and pump.
Having read a variety of the other posts on techniques to reduce noise, [b]I am wondering if this will make the pump louder? and maybe the convenience factor won't be worth the noise?
My experience says that the coils of flexible tubing will make it quieter, especially if they are on both the inlet and outlet of the pump. Link to My pump replacement.
In my original installation, the output of the pump was connected to hard plastic plumbing tube that was also connected to the "City Water" fitting on the side of the trailer. The input to the pump had a valve in a "flex" line that was so short, it was rigid for all practical purposes.
The 30 year old pump was mounted on rubber grommets which had fossilized with age and were no longer flexible, either. When the pump vibrated, EVERYTHING vibrated.
Because my old pump had such poor water pressure output, I decided to replace it. I decided to follow the new pump's installation directions exactly
. At first this looked to be problematic, for there wasn't enough room to configure the new pump the same way as the old one. Re-orienting the pump and taking advantage of the long flexible hoses on both input and output did the trick!
The new pump had new flexible rubber mounting grommets for the screws into the floor. The pumps vibrations do not transmit to the floor. The reinforced hose on the input and output prevent the pump vibrations from transmitting to the tank, hard plastic tube, "City Water" connection, or the wall of the trailer. The hoses do not touch any other part of the trailer, and do not lay on the floor; they are suspended between their end connection points.
My pump is now silent!
When I turn on the kitchen faucet, all I hear is the water in the sink, as if I were using the "City Water" connection.
