Water pumps
« on: December 05, 2012, 05:26:00 PM »
Anyone using a water pump that is 120 volt? If so, what brand and model number are you using? I only have two sinks, shower and ice maker to keep busy. Shower head is water miser at 1.5 gpm.  Will be using PEX 1/2 for the entire system.

Any help would be appreciated.

Thanks

Grant

I found a low priced "well pump" that is 110VAC and maintains a constant flow and pressure with its built in pressure switch and bladder tank.

I am sure Clifford will correct me if I am wrong but I think some of Prevost conversions came with a 120V pump.  If so, maybe one of those guys will be able to give you a part number.

Flojet from lowes. I can tell you it's quiet (mounted it in rubber bushings) and works amazingly well. Plenty of pressure....way more than you'll need. If you go this route, it will NOT work unless you add a check valve between your tank and the pump AND you plumb in an expansion tank. I have experimented over several months with the system and now have it down perfectly. I'll post pics later today.

Thank you Scott, that is exactly what I was hoping for. I have tried to build the bus where most of the pieces could be quickly replaced at your local big box store! I would appreciate any details (model#s, schematics, ....... ) and any kind of insight you can provide.

Regards,

Grant

To me that looks like a Chinese Built motor. And it is rather bulky. Shurflo makes a 120vac water pump that is just a bit more then the almost $100.00 they are asking with shipping. Stick to what's designed for motorhome use-you'll be much happier.  Good Luck, TomC

Tom, I have much less experience than you, so I say this completely innocently, I like having house parts in our bus. They work better for the most part, don't leak, can take city water pressure without blowing seals, and provide house like comfort. The flojet we have has been used constantly this fall and winter and has run dry for literally 24 hours straight (don't ask) and still performs like a champ. Here's a photo of our setup:

Grant,

We purchased a DC powered Remco 5.5gpm variable speed pump.  It is supposed to keep the pressure between 60 and 80psi.  We are still hooking up our plumbing and have yet to test.  

Go like Scott mentioned and get yourself an accumulator to get rid of the constant off/ons and knocking pipes.  

We are trying to get as much as we can on DC power so I cannot really help with the 120v pump question.

Check our website.  I just posted about our plumbing updates this morning.

Click on the "Shell" link at the top of the page.

I'll report back in once we have all the fixtures attached and everything is up and running.

I like keeping my pressure to around 40psi. Less strain on the plumbing and less flow that won't waste more water. Good Luck, TomC

I am using the typical 12-volt Sureflo pump, but when we started, I checked out a number of small 120-VAC pumps at the local Home Depot that are designed for fountains. (The decorative kind of fountains, as you might put in a patio, or in front of an office building.) They have an amazing selection, in many different amperage and gallons-per-minute ratings. Some are small enough to fit in your hand. I wish you success!

    Yeah, in my experience, 40 is plenty (showers, kitchen sink fill, etc.).

The issue I have with the jet pumps is they are such over-kill for the application - the key feature they have is they can pump from around a 90 foot depth of well, and we run them usually with the water supply higher than the pump.  They are usually 1/2 hp (or more), which means about 5 amps at 120 vac and a big surge at starting.  If you are on a 30 amp pedestal that can be a big chunk of available power, and if you try to run it from an inverter that's around 60 amps at 12 volts.  They also weigh a ton - around 50 lbs.  A pump like this one is designed for park model RV's and is on-demand activated, small, light, energy efficient.  http://www.pplmotorhomes.com/parts/rv-pumps-water/shurflo-pump.htm  It's not that the jet pump doesn't work, it's that it's like using a sledge hammer to drive finishing nails.

Ditto what Brian said :-) true story. We are pretty much 50 amp dependent with our coach setup but we have spent several months happily hooked to 30 amp without issue. But yes, definitely overkill. This thing pumps some serious water. If we ever have a fire, we are putting it out :D

Scott, go easy on that water to put out a fire on an RV. Typically most RV fires are grease, fuel, A/C refrigerant, oil, power steering, and probably more fires for which water is totally not the appropriate medium for extinguishing them.

Get several on board extinguishers appropriate for extinguishing a fire of chemical and electrical origin and keep them charged. One of our friends had work done on their A/C system. After driving for several miles, one of the hoses ruptured and spewed refrigerant onto the engine. The surface temperature created the ignition source. The end result was not pretty. Hand held extinguishers were not big enough to put out the fire.

Water is good for extinguishing a camp fire and that is about it. Of course if your campfire has set off the surrounding woods, call 911 and get the heck out of there!

That's my 2 cents worth.

Sage advice. We have a huge (my wife has trouble picking it up) extinguisher. Good for three fire types. Will be buying a second one too. But yes, fighting fire with water isn't always the best option.
