MJ:

I know you made a "u" shaped fresh water tank out of pvc. That thread might be of interest.

I have looked and looked for one thread where one member made 2 "u" shaped tanks that nested inside each other one was fresh water and one was grey this was a well done installation as was yours. These 2 threads I think would be of great value to those looking for ideas for on board storage.

Sure hope that no one got PLUGGED.

Hey bobhenry,
I think you might be referring to Brwbier's installation. Here's quote from a thread called

WATER TANK AND DRAIN in Teardrop Construction Tips & Techniques

It holds 5.5 gallons of fresh water and 5.75 gallons of gray water.
There are several other advantages to the way I built. If interested just ask or look through my album,

That be it !

Thank you !

Critics rave: "The new Plumbing and Propane topic area is a hands down success"






Or was it pants down?

I love the freshwater and grey water tank ideas, it seems simple and effective, and a real space saver

Right, Mind your "P"'s (& q's) or you'll end up in hot water here.

Seriously, I have been thinking along the same lines for the water storage of my build. PVC x 4 inch OD capped, under slung. I have 2x3 metal square frame (4'x8') with 2x3 metal square cross beams at 2' intervals. I have some strapping from gas tanks (new) and if nothing else, several straps of metal pipe strap with metal taping screws. Insulation for the hot tanks. Surmising 1/4 of the total water to go through human consumption...


but you are saying I should go with all U shaped tanks, probably for flushing reasons?
(I'm probably going to change this to 1 hot, 3 cold, 3 grey...)

any problem with air in the tank then, and pumping out point? (slight tilt to tank? bends off perfect for a slope to pump point?)

any input on using a 12v air compressor to do double duty, pressurize water system and standby for tires, inner tubes, mattresses, instead of a pump for both water and air separately? (if the water tank is pressurized with air, and you open the valve, water will come out the faucet... )

I suppose one of the problems is that, now air tight instead of just water tight, and lift distance for pressurized tanks...

I suppose that the other end of that is that little water comes out due to slow compressor, when the tank is full, and lots comes out when there is little water, because more air to pressurize for longer flow...

I have also been thinking super cheapie, and getting "drill-shaft" type water pumps, because I have a bunch of old battery powered drills that the batteries are gone on, and not worth replacing the batteries, but for a 12v pump, just add the $7 drill shaft water pump and some wire... (reduce, reuse, recycle)

have some extra wire and you have a 12v drill handy, doing double duty as the water pump. :-)
check the voltage, amps to run, wire wound resistor...

The "drill powered" pump I tried was a total failure due to the bearings being made of graphite-impregnated bronze. Works great as a bearing, not so good for contact with drinking water!

A 12V potable water pump isn't that expensive ($40) that it's worth endangering your health by using a device not rated for drinking water.

I've been using this pump in my home brewery for over 20 years to pump hot water with no issues and complete reliability. http://tinyurl.com/789jwcr

Actually that looks pretty good. Thanks.
So I need one for hot and one for cold?
What about a pressure sensor for when I turn the tap on?

is the "feet of head" for hose after the pump or hose before the pump?

RV supply houses have pressure sensors to automatically turn on and off your pump, but I find it much cheaper and simpler to just put a switch in the power line to the pump. When I want hot water, I turn on the pump, then turn on the hot water. Doesn't require a $$$ pressure sensor.

Always throttle the output of a pump, never starve it, so provide full flow to the input then put your control valve on the output.

Feet of head is measured on the output. Mine easily pumped hot water 7 feet high at a rate of more than a gallon per minute.

Those Dayton pumps are not self priming, so it has to be located below the tank outflow, or you have to provide a manual priming method.

so this diagram looks right so far?

That's how I would do it.

Don't forget to insulate those hot water tanks. You'll lose all your solar heat very quickly if the tanks aren't insulated.

Can I use something similar to the foam wrap they use on air conditioning hose, coming in from the backyard unit to the heater/furnace of the house? They make that stuff for 4-6" outer diameter?

I now have an idea to have my fill point at the right front corner soffit/eaves... That would give me an access point, semi-hidden, with some elevation for the venting. I'm wondering now, we have the grey water storage and drainage. Even slip some chlorine down there for cleaning, is there grey water flushing? (pressure inlet -> flow through grey tank -> to grey drain?) to clear out any sediment of dirt?
