Can I use non toxic antifreeze for water system.

[G-A-R-Y]

My VW van has a strange water system which makes it difficult to drain completely, I searched for caravan/motorhome antifreeze and it's available for water systems.

Has anyone used/tried this.

All the anti freezes I know of are usually toxic, so can't be used for drinking water. What water system do you have?

 

[chaser]

There does appear to be such stuff on Amazon. Wouldn't have thought so.

Caravan antifreeze

It's a real thing.

Caravan antifreeze

Instructions say, For winter Starage Only... not to be used for drinking..
I may be wrong, but I get impression you want to use it to save draining system down and use as usual??
Please correct if wrong

RVs commonly use a pink antifreeze. Still have to flush system after using though. Starbrite. I put a little in tank after draining and fill u bends. I isolate the boiler first.

two or three letters of vodka and bonus drink it in the spring

Use starbright on our boat it's also non toxic to aquatic life

 

[Rogerwyn]

Vodka

On my boats, which were subject to -10deg C, empty water tank, add a/f then pump through every tap and the toilet. Flush out in the spring.
Isolate pump and open all taps. Never a problem.

My camper is VW Grand California, it has a complicated water system compared to our caravan, lots of pipes and manifolds, even rear external shower and toilet flush.

The bathroom shower tap is notoriously difficult to drain down and pushes appart which in turn floods out of rear doors.
Plus you can't run the pump (it won't work) to pump the system dry.

I thought I'd run this stuff through a few times and STILL drain down keeping it for next time.
Plus I'll put a bit down the waste traps x3.

Maybe If you left the heating or a heater on low it wouldn't use £23 worth of electric. If on driveway EHU of course

I bet it would, have you tried any of the sites with metered electricity supply, you'll be suprised.

Business prices for electric are higher than for domestic use which is why it's surprising how much it costs!

Used it on our boat once - was a bit of a chore to drain the tanks and rinse them on the boat, so only once - plan to pop some in the grey and black tanks in the van this year, mainly to stop the valves from getting stiff with dried out crud, especially the gate valve on the black tank.

Up until now draining down the clean water tank/pump/showers/taps etc has been fine, so although tank rinsing is simpler on the van I doubt I'll use it on the clean tank.

That'll work fine I imagine, have you seen these things? https://keepfloeing.com/shop/motorhome/, got me thinking that blowing the system through with taps open using our tyre inflater might be beneficial. Haven't thought it through properly and might be more fuss than it's worth since I've never had a problem on any of the boats/vans we've had - but we are on the relatively mild South Coast.

"sites" so you go on holiday and your van is possibly freezing inside?

No, I meant at home with a heater set on maybe 10°c
