On site a while back the chap on the next pitch to me, before setting off, opened up his freshwater drain and let the water drain out onto the pitch. I’ve not drained my unused fresh water onto the pitch before as I just empty both tanks at the service point before leaving as it’s only a few minutes job. I also don’t want to leave a soggy pitch for the next arrival. So emptying unused fresh water onto the pitch before leaving. Thoughts?
