Drinking water onboard options

[TheMobileWanderer]

Not bought or installed yet - but yes, that's what I'm planning on using along with a carbon filter and some sort of pre filter at the fill up probably.

Yeh, I'm mulling over a few things about it. Two fresh water tanks, one higher than the other. Fill from the fill valve and the water will flow through a strainer into tank 1. (Strainer similar to that on windscreen washer reservoir). From there, it'll flow through a carbon filter, in its own time, and into the second tank to be stored. (Same idea as a Brita filter thing in a fridge). Then when it's flowing to taps, it'll run through a UV filter. I don't know whether I would drink it because in that case, I'd need to refrigerate it too.

Ooo, I'd like to know more about the three stages please.

These vary from system to system but you normally have a sediment filter to remove 'large' stuff (5 microns) then a particulate filter (0.5) and finally a 'virus' filter (0.001)

To kill virus / cyst level stuff you need either nanofiltration, reverse osmosis or UV (well, distillation will also do it but that's not practical in a motorhome usually!)

Reverse Osmosis is probably the best in terms of removing everything from the water but also the most expensive. It's also quite wasteful of water and will strip all the minerals out of your drinking water and deposit them in a concentrated form into your waste.

Might make sense for full timers but for most of us a filtration system is probably the way to go. You can add UV to any filtration system as a final stage.

For my needs I think a single filter + UV stage will be fine. I'm not going to be filling up from muddy puddles or sea water.

This is the system that’s being fitted to our soon to be built van. There are other bigger systems on their website.
