I guess there's only one way to find out![]()
You'll probably be fine tbh. I never water the garden anyway,the only reason I have a hose is for the fish tank which needs 60 ish new litres a week. For that it doesn't matter where I get the water from, it's still 60 litres!
If you are particularly concerned another option would be a bucket on a ladder or something with just a small length of hose secured in it. Just siphon the water out and you'll get enough to rinse the car from 2 buckets tops I would have though and won't get locked in the slammer for 15 - life
