Hi, I have a pool sentry automatic pool filling gadget. It works fine but I need to find a hose that can be under constant pressure for it to work. I've tried a couple of new hoses but they're not made to be under that pressure and therefore leak at the fittings. (I have the faucet turned on a little as possible to lower the pressure.) Does anyone know what kind of hose I can use without leaks? Thanks!
