Showing Grey Water storage & grey water drain hose storage.
Hose storage pipe is 50mm comms conduit with 2 large sweeping bends from Electrical wholesale. Grey tank made up from 150mm storm water pipe, reducers, bends etc then to presssure pipe with a Vista 1 3/4" pvc valve & screwed adapter. The tricky bit was finding fittings to go from storm pipe to pressure pipe. Plumbing Wholesaler said it couldn't be done but was happy to let me walk around trying different fittings. I found fittings that did the job. Unfortunately I don't know the details & they have been painted. All I can read is the middle fitting is a Hansen brand. If you want to build this I suggest finding a large plumbing wholesaler that is happy for you to walk around trying different fittings. Happy to try and answer questions. Cheers Jeff
