Replacing Water Pump

[Native Tex]

Just bought one of the sensor pumps to replace the old thumper type. Before I start the replacement, are there any special issues that I should be aware of? When looking inside the cabinet it seems to be a pretty easy exchange with the fittings and electrical. I assume I will need to close the valves from the hot water heater and input lines in order to help cut down on the water leaking into the unit. Ideas or comment welcome.

Thanks in advance

I would blow out all the lines. I.E. winterized and then replace. I am interested in your report on the new pump. You might consider adding a 2 gallon accumulator from Lowes or Home Depot at the same time. They are a lotcheaper than CW..

Dont forget to run the inline filter that can be purchased for the pump on the inlet side.
good luck

Put some rubber/foam pad underneath it when you install it. I used a garden kneeling pad. That will cut down on the noise quite a bit. The smaller black accumulator tank works fine too. Keeps the pump from coming on as often. Can be installed anywhere there is a cold water line. It was a little crowded near the pump, so I installed mine on the inner cabinet wall near the kitchen sink outlet. Works just fine.

I just recently replaced my pump. I mounted the pump on some heavy rubber pads I made out of my truck bed mat. When I installed my my fifth wheel hitch, I had to notch out for the rails. I also added a 3 ' piece of white water hose on each end of the pump. This will dampen the sound transfer from the pump to the pex water connection. The Water Pump Store carries the kit for $20.00. These 2 items greatly reduced the noise and vibration of the former pump.

scroll down about 3/4ths of the page to see the hoses.

This looks like a good idea. Which model did you buy?

I recently replaced my old thumper with this one: SHURflo 4008-101-E65 3.0 Revolution Water Pump. I checked CW and then looked on Amazon. Paid $68.32 about $20 less than CW. Just saying...

Anyhow, the replacement was a breeze and the heavy rubber mounting on the pump didn't completely eliminate the sound, but it is waaaay quieter. Only thing I needed to provide were the electrical butt connectors.

Specs say the pump is 5# more pressure, but wasn't noticeable to me.

Now if the pump goes off in the middle of the night, it doesn't alert the neighborhood.

Joe, I replaced my water pump with same unit as you, but it was because the check-valve wan't working and it was filling up my fresh water tank. We don't dry camp so we hardly ever use the pump and rely on city water pressure or campground furnished water.

Good advice! I hate the noise our stock pump makes!
