Sub zero winter temperatures can obviously lead to freezing water tanks and pipes.
Not only will this stop you having your morning coffee but could lead to burst pipes. Not the best way to start any day.
We read somewhere we should pour whisky into our tanks but we have a better use for our Johnnie Walker.
So how do we protect our water tanks and pipes from freezing?
If your campervan water system is indoors, you probably don’t have to worry too much about your fresh water tank, if you keep the inside temperature above 0°C.
But our fresh water tanks are underslung outside.
Skirting can provide some level of protection. And we park so our water tanks get as much sunlight as possible.
We also recommend keeping the water tank about three quarters full. This way it’ll take much longer to freeze and if they do freeze, there’s room for expansion.
You do not want frozen pipes in your pump or water heater as it will do irreparable damage.
If you’re in any doubt, winterize the water system by completely emptying it and using LP air to dry out the pipes.
Use bottles of water instead and consider alternative shower options.
Never leave your water hose connected to the supply pipe because it’s likely to freeze solid, making detaching it next to impossible.
Alternatively you could use a heated water hose.
For waste water, it’s best to leave the drain valve open and let the grey water run into a bucket.
A composting toilet performs better in cold temperatures so a good option if you plan to live in your camper in the winter.
If you have a campervan toilet with black tanks though, make sure to not let these fill too much and pour antifreeze into them.
You really don’t want those tanks or pipes bursting!
