I'm in need now of a good quality bilge pump. I'm making my own pure water in my household and not straight into the tank in my van like I used too. Just wondering what are the best bilge pumps in your oppinions. I need a good speed (perhaps, to fill a 450 litre tank in say 10-15 mins?) Also good long lasting quality. P.s. I'd prefer it if only people who have had hands on experience with these pumps comment. I need accurate/ish advice. Thanks alot, James.
