Gayflower: Spring 2025 Plan This documents the replacement of the fresh water system in the Gayflower that was completed May 2025. "Before" Photo: 0. General conditions Install plywood on rear wall to support the plumbing stack for the pump outlet. DONE Get a big tool box and parts box to organize all our plumbing tools and parts  DONE 1. IBC Tote Replacement Replace all seven totes with new ones and completely replace all plumbing connecting them. This design had one bug: the pump would not work without a check valve at the input. We added that in and everything worked great! Design considerations Use flexible hoses instead of PVC with glue, for easy replacement, more flexibity, and less likely to break Pump requires 1" diameter inflow. To accomplish this the nearest IBC tote will be connected with 1" PEX-B. All the other totes can be connect to each other with 3/4" hose just to allow them to balance with each other. Shutoff valves everywhere for safety and quick repairs New plumbing configuration A IBC tote  B 2" Camlock valve, preinstalled on tote C 2" Camlock to 3/4" Male Garden Hose adapter D 2' long 3/4" Female to Female Garden Hose Extender (get some 1' as well to minimize slop) E 3/4" Garden Hose splitter with valves (F - M - M) F 5' long 3/4" Garden Hose (M - F) G 3/4" Garden Hose three way splitter with valves (F - M - M - M) H 50' 3/4" Garden Hose (M - F) I Hole in floor J 2" Female Camlock to 2" Male NPT Adapter, Stainless Steel ( example ) K 2" Female NPT to 1" Female NPT L 1" Male NPT to 1" Sharkbite M 1" PEX-B N 1" - 1" - 3/4" Reducing Tee (Sharkbite) O 1" Sharkbite Elbows P 1" Sharkbite to 1" Male NPT Q Pump, with 1" Female NPT inlet R 3/4" PEX-B S 3/4" Sharkbite to 3/4" Male NPT T 3/4" Female NPT to 3/4" Male Garden Hose U 3/4" Garden Hose Shutoff Valve (M-F) V 3/4" Garden Hose Male to Male Coupler The pump requires 1" diameter input, so it draws from the nearest tote using 1" PEX-B (put together with sharkbite fittings). That tote, and the other six, are all interconnected using 3/4" hoses, which allow the water to seek a level between them. 2. Evaporative Cooler Supply Rerouting The water supply line for the evaporative cooler should be rerouted so it does not interfere with that IBC tote. Also, it might be responsible for the leak at the top of the pump. 3. Rework plumbing above the pump The main goal here is to make something that allows for quickly swapping out a failed pump, and eliminate the PVC+glue that is prone to leaks.

Urinal leak repair Reference photo:  Not sure what size PVC this is. It is most likely 1 1/2" or 2". this might be the world's simplest fix, just glue it back but without knowing what it's connected to underneath, it might be a situation where whenever the black water tanks shift around, they move the pipes To repair this, we would need: Short length of PVC pipe ( 1 1/2" ) ( 2" ) PVC couplings ( 1 1/2 ") ( 2" ) Fernco flexible couplings ( this or this ) PVC male - slip adapter Purple primer Fine tooth saw or PVC pipe cutter PVC cement Everything here is going to be available from Home Depot.
