I'm currently looking into the idea of adding a shurflo or some other on demand water pump to my QuickSilver pop up. Since its not all that common to see the pop ups with on demand systems, especially in the LivinLite rigs I figured I'd ask here.
I currently have my system plumbed so that with the turn of a valve I can use the hand pump to my "faucet", or switch it over to accept city water. My theory is that I should be able to add the pump city water side of the setup which will turn it into more of a pressurized side vs non-pressurized. I'm trying to minimize valves and connections, otherwise I'd just add a manual bypass.
My biggest sticking point is not knowing if these pumps will be damaged if they are faced with some sort of inlet pressure. In other words, if I hook up to a standard city water connection at a camp ground (without the pump being turned on) will it simply flow through the pump without damaging it?
Any thoughts?
Thank you,
Sean
I'm not sure I quite understand the way you're thinking of setting up your pump but I don't think you can just drop the pump in-line with the city water inlet (if that's what you're saying). Here's the way my 13QBB came from the factory, if you could put the pump inline I think it would make it easier to plumb but since they don't I'm assuming you can't. Do you have a tank at all?

The Winnebago Trend has a tankless water heater as part of its standard package. Researching how they did it might be a good place to start. I want to do the same thing for my TT when I get it. The folks from Atwood highly recommended the Shurflow accumulator for their tankless.
[p]Found this video on the Girard. In the middle it talks about their latest model that is a nice step up in how to regulate temp. This is the exact model the Winnebago is using. [/p][p]

[/p][p]I then found a long thread on the Airstream forums that basically concluded that this heater does not work. They all pointed to [a href="http://www.precisiontemp.com/"]http://www.precisiontemp.com/[/a] as the one that works best.

[/p][p]For what it is worth, Atwood licensed the precisiontemp patents for their unit. See [a href="http://rvdailyreport.com/industry/precision-temp-teams-with-atwood-to-design-tankless-rv-water-heaters/"]http://rvdailyreport.com/industry/precision-temp-teams-with-atwood-to-design-tankless-rv-water-heaters/[/a][/p][p]
[/p][p]Precisiotemp can go up to 55,000 BTUs while Atwood caps at 50,000, but Atwood is much less expensive.

[p]Ok, found a thread on the Atwood. Seems the Airstream people are all over this: [a href="http://www.airforums.com/forums/f445/anyone-install-new-atwood-tankless-hot-water-100360-2.html"]http://www.airforums.com/forums/f445/anyone-install-new-atwood-tankless-hot-water-100360-2.html[/a][/p][p]
[/p][p]And here is a thread on the accumulator, at where else but airstream... [a href="http://www.airforums.com/forums/f163/adding-water-pressure-accumulator-100341.html"]http://www.airforums.com/forums/f163/adding-water-pressure-accumulator-100341.html[/a][/p][p]

So, for me, I will most likely go with the Atwood unless I get lucky at the time of purchase and the precisiontemps are on sale somewhere. I will absolutely get the accumulator.

I think you understand the concept I'm going for. Essentially I've set things up so I have a single input port on the camper and route it to correct line into the faucet. I think I should be able to take the inlet side from my "tank water" line and put the outlet from the pump into the city water line. When I get to a computer I'll try to draw up a diagram. I'm visual so it's hard to explain.

I appreciate the effort even if it went on a bit of a side note :)
