Hi All,
First post, though I have been lurking here for some time. Great forum, love the comments and wealth of knowledge, keep up the good work!
Right, so I took delivery of our 17.58-1 Oct ish? 2017, it has two water tanks. Though being a -1 (opposed to -3) there is a manual hand pump and no 12V pump. That was just not going to fly, so a 12V pump install was on the cards from the get go. To be honest I thought it came with a 12V pump, oh well mod #1.
What I set out to do:
1) add a 12V water pump.
2) keep the mains and pump water lines as separate as possible (avoid mixing water and complexity of failing/$$$ components NRV etc).
3) use existing tap mixer, with the intent of keeping inside of van looking neat/factory.
4) mains and pump water at the draw bar for the portable hot water system.
I used all John Guest fittings, no elbows, straight lines as much as possible. I have removed the hand plumbing pump altogether and connected the factory plumping to the low pressure pump input. Hand pump itself is still installed, will replace in the next mod with an under sink water filter. Something like this.
12V pump is installed under the van, main reason is to keep all fittings outside the van, The only fittings are the JG Brass line to tap mixer connection (*Try posting a bit more so your post isn't boring*) which cant be avoided and the city mains input line, though more would be added by installing the under sink filter and dedicated tap where the hand pump currently resides.
With the draw bar line, I wanted to retain the one tap, and I did not have access to more black (UV stable) high pressure line. Using JG taps seemed a simple way to reduce the plumbing complexity, negate the need for another NRV and allow me to keep the single draw bar tap. This is all at the expense of needing to turn both taps under the van to switch the draw bar water source. If for some reason only one tap was turned water would be allowed to mix lines. Time will tell how good an idea this one was.
Why am I posting this thread? I want your comments and thoughts on how I have implemented my installed based on the above four key points. What have I missed, where may I have issues etc
One thing I can see already in the making of the below drawing is that when the mixer tap is opened equally between water sources (connected to mains) I may need a NRV installed before the pump to prevent water flowing through the pump to my tanks.
