What do you like?
What PSI is best?
GPM?
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.

Same here.
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.

I need to replace my FloJet VSD 4.5gpm that got destroyed by surprise freezing weather.
I have 24V DC and 110V AC available at all times in my rig, and I'm tempted to either:
1) Plumb two smaller pumps in parallel
2) Get a cheap 110V pump and switch and accumulator tank
If I put two smaller (say 3gpm) pumps in parallel, am I going to actually get 6 gpm out of them?
And for #2, any suggestions for a cheap switched 110V pump I can pickup?
I'd like to stay over 4 gpm and I'd like my pump to last longer, I've burned through 3 VSD pumps thanks to various issues.
Look at the way Shurflo sets up a 2 pump system model 4558-153-E75 it looks like 2 pumps in tandem but 10gpm @ 55psi they are pricey if you buy from a marine store

We have a two year older model of this one in our bus. Best pump out there...done ;)
We have 3/4" pex coming in and it pushes through 2 house sized filters and is often more pressure then most parks we are at. Its about 45-60psi at the faucet.
Its variable speed and doesn't hammer but I would still suggest an accumulator. It is not much louder than a cheap pump but should take noise into consideration when mounting. Mounting an old mouse pad under the feet helps to absorb vibrations.

Looks great, but it's 12V. I have 110VAC and 24VDC easy throughout the bus, but not 12V.

Sure are pricey, but that's some amazing stats.
I wonder if they need different sensors, I've wondered if two pumps in parallel would both merely try to pressurize the line to get 4.5gpm flow thereby both working less but not improving flow (though saving you if one breaks).
I have three of these tandem setups and they work very well. In the Prevost it is the same as being hooked up to city water and you can not hear them anyway in the coach. I recommend the shurflos highly

I've always had Surflow in the past but at the recommendation of the mfg of my instant hot water heater I now have two Flo Jet pumps rated at 2.9 gpm ea @50 psi. One for cold and one for hot. Though they say they run at 4.4 amps ea, I've not checked. What I do know is that they were reasonably priced and solved the water mixer problem in the shower--no more heater shut off mid shower. Burrrrrrrrrr. At nearly 6 gpm possible I'll have to be careful. I can only carry 60 gal fresh water in my tiny bus. Jack
Jack did you install the hot water heater pump just right before going into the hot water tank?

Hey Lee. Yes, I did install my pump within inches of the on demand water heater. Actually both pumps are housed within the same steel box that contains the heater. My thought was that if (when) the pumps leaked the water would run out the bottom air intake of the box and not ruin my floor. What is your take? Jack
Good idea think I will do the same, I like the idea of a separate pump for the hot side

Lee, I forgot to mention that I also plumbed for the hot water pump to recirculate hot water back to the fresh water tank from the furthermost point of the circuit via a solenoid valve. If I want only limited hot water flow, I leave the bypass solenoid valve open. If I want full hot water flow I switch the solenoid valve off and get full pump pressure. This both gives me instant hot water at the spigot as well as eliminating running cold (hot) water down the drain. My instant water heater is sensitive to both pressure and flow rate. The dedicated pump and the recirculating solenoid valve solved this problem. I use a three way switch, (like a hallway switch) one in the bath and one in the kitchen to manage the solenoid valve. Jack
