I have a flojet --- I don't know the model but has served well.

Doesn't need a pressure tank and we have no shortage of pressure.

I will operate on 24 or 12 volts.

I use 2 Shurflow Whisper Quiet pumps plumbed in parallel-meaning you can use either or both. I have both on when someone is taking a shower and dish washing is happening at the same time. It only puts out about 35psi-but it is more then enough.
I like the old style water pumps with mechanical pressure switches. I was at a RV show talking to the Shurflo factory rep, and he said the mechanical pressure switches (that are adjustable) are like a truck-very reliable. While the electronic variable speed are nice, he said that when they go out, they don't work at all. The Shurflo factory rep said he personally would take the mechanical pressure switch over the electronic. Good Luck, TomC

Hi Tikvah,

Just replaced my Flojet with a new 3GPM and had the old one repaired for use as a spare.
The pumps are OK for the kitchen, toilet and sink but leave something to be desired in the shower.

I considered a higher pressure, high volume, 120 Volt pump from Lowe's - should have done just that!  The cost would have been near the same, longer warranty, and a real shower. 

P.S.  Already had an expansion tank.

I have not had any issues with the flojet for the shower. As far as washing dishes when showering you can avoid that by getting the wife / girlfriend / partner in the shower with you AND it will save water. On the noise side -- the pump is close to the back of the bus and it does let us know when it is running. Just adds to the personality of the experience.

Since we usually want to conserve water when running off the tank, it would seem that a higher flow pump is a disadvantage.

I love my Shurflo Extreme 5.7!!
I found a deal, and bought 3.  Only need 1 because of how powerful (65psi)  it is, but I keep the 2 others on my bay for spares.

I have the same one as morefire. In fact I also got a deal on about 8 of them.

I plumbed 2 of them in so if one quits, I can just turn a valve and the other one picks up the load.
I can then repair or replace the other when it is convenient. Haven't had any trouble with these.

I use less water per shower with the high pressure. If I'm not hooked to water, We use navy showers.
We have 100 gal and quite comfortably go 5 days with showers every day. That's probably a little less
than 10 gal per day each. I do not want to use less and I think Momma would have a conniption if I
suggested it to her.

I have the Flojet Sensor VSD pump in my bus.  I bought a spare relatively cheap, but not really sure why I bought a spare.  The pump works quite well and I like that it works on 12 or 24 volt.

We also use a Flojet sensor VSD 4.5 GPM pump. It provides all the water we need at 45 PSI.

Good luck, Sam

Aquajet pump.  Love it. 60 psi. Variable speed so you don't have to put a pressure tank in. I installed two 2-gal tanks anyway, and prefer it with the tanks
as opposed to without. The pump runs less often, but at full speed for short bursts, rather than running continuously on a low rumble during water use.

Make sure you get a screen and place in the supply line. We had an issue with teflon tape bits getting into the diaphragm before we installed the screen.

We had a Shurflo 5.7.  It was a great pump. The pressure switch went out on it.  As it comes out,  this was a common problem. Guess what?  They don't have parts for the pump.  Buy a new model they say.  I explained that we probably had less than two full months of use on this pump even if it wasn't in warranty.  After a heated discussion they agreed to replace it with their "new improved smaller pump" for free.  I wouldn't buy another Shurflo product.

Like Tom, I have two SHURflo pumps in parallel, so I can use either or both as needed.   Mine are the simple old tried-and-trusted 2088-422-144 model  -  only 2.8 GPM, but by all accounts they go for ever, and are simple and cheap to fix if anything needs work.   A lot of pump failures are caused by FOD, so a strainer upstream of each pump is prudent.

I set my Watts 263A city water pressure regulator to the same 45 PSI as the pumps' output pressure.   I also have a strainer for the regulator to keep nasties out of it.
