Why do you want it sealed when disconnected? It won’t be drinking quality water anyway.
Well to stop crap getting in and being forced up through the pipe if left open to crap and insects etc. Guess I could find a physical cap to cover for it.
What will you do for drainage inside the garage?
No need, it’s for home brew just to fill the Mash Tun. It gets mashed, boiled then into the fermenter. I do clean up around the side of the house near the drain with the hose pipe. Also for use with the emersion chiller for cooling the wort after boiling save me walking around the side of the house every time I need to adjust flow rate of cooling water or turn it on or off. Using the hose at the moment but its a bit of a faff so just looking for a neater solution to make brew days go a bit smoother.
Oh well, wondered if there was a clever fitting for some other purposes I could have used.Think there is something on my jet washer that would work, I’m sure the fitting on that seals when the high pressure hose side of things disconnects. Back to the drawing board.
