Fresh water supply plumbing

[HoBoJo Busman]

I filter once, when filling the fresh water tank...Then as the pump sends the water to it's destination inside the bus, the water is filtered through two additional filters, a charcoal and then a cotton wound one.
If I am pulling directly off an outside faucet, the same two filters are filtering the freshwater after it comes in through the reducer at 45 pounds PSI.

hose to 2 filters then to 150 gal. tank then use the pump for all water for the coach . then through a 6 filter RO system and a uv light for drinking and cooking at the kit sink .

hot water is diesel boiler / 15 amp elect 11 gal. marine w/h tank but most of the time the elect. part of the water heater does all the work and we can have back to back showers and still have hot water to spare

do your system your way

Van,


Fresh water is routed as follows.

There are two inlets, each accepts pressurized fresh water via a garden hose.

One inlet supplies fresh water to the fresh water tank or the house supply. There is an inline valve that directs the flow to the desired destination.

The second inlet on the opposite side does the same thing: supplies water to the fresh water tank or the house supply. A second inline valve directs the as desired.

The water pump is fed by a hose connected to the fresh water tank. The output line goes to a T fitting that is located on the pressurized section of pipe described in first inlet line.

Sounds a bit involved but actually pretty simple and provides fresh water from two inlets located on both sides of the bus or from the fresh water tank via the water pump. However, it is not automatic and the valves must be manually set; hardly an issue for us since we nearly always are in boondocking mode.

Thanks all for the responses, all good set ups  and as was said " do it your way".
Upgrading to Pex is a for sure thing which we will be doing to our new system.

As a side note regarding Pex, has any one seen or tried this Milwaukee crimping tool yet? I have and although it is quite pricey just to do a one time system install for the DIY'er this thing is fantastic!

I only use the Zurn PEX crimp rings so it wouldn't do me much good

Yes, I love the dang thing!!! Never had a connection leak, though I wish I could say the same about the ones that I screw together...

Are they copper Cliff?

That price is crazy for for any one than a plumbing contractor. Manual ones much cheaper and do a good job. It is nice though.
Hopefully Harbor Freight will come out with one for 80 bucks next year.

Stainless steel Van lol and I have the tool to remove it that I have used a lot crimping on the wrong fitting

or you could use this set and put a ton of diesel in the tank and go traveling . I have a set like this and they work great in tight places + very easy to crimp .

I was going to mention that set after looking, but I'm out of popcorn.

Recently on our fresh water system we added a 12 vdc bypass solenoid with a programmable timer on it so when you turn on hot water in the shower instead of it going down the drain while waiting for it to warm the solenoid diverts it back to the fresh water holding tank fot an interval of time you set it for then when the solenoid deactivates water at the shower head the temp you want it. Save lots of water with that gadget. It can also double as a fresh water tank heater to rise the tank temp if needed. Real handy upgrade for around $50.

Not sure you can call it the "fresh" water tank once whatever is in the drain ends up in tank. Most often that water goes in the "gray" tank. Not sure it's wise to put anything potentially unsanitary in that tank even if it's no longer potable.

I believe Dan is diverting the water back to the fresh tank before it ever reaches the shower head in the valve until it heats up. Once it's hot, the water goes to the shower head. That way none is wasted down the drain waiting for hot water to arrive in the shower.

[chessie4905]

Some houses use that setup when water heater is far away from some faucets, although it is an insulated loop.
