A 6” PVC companion flange cracked and would leak when pump #2 would run. Being down to only one pump didn’t leave this school with any redundancy, so we ordered parts and showed up today to cut out the old and replace with shiny new.
I glued some of the joints together while we worked on other stuff to extend the drying time. Some joints cured for over an hour. But the quickest was 30 minutes. You’re safe waiting that long in my experience.
Human would have broken it. Butterly's like being supported in metal, not plastic. As they age and being around corrosive water and no galvanic protection, it will stiffen up. Add in a human not knowing what direction to turn (no markings), you can figure the rest.
Yes, it was probably operator error. That being said, a person would have to absolutely RIP on the handle of that valve to break the flange, so I’m not 100% convinced. The discharge side of the pump was showing around 80 PSI once the pumps are on. But I’m not sure how accurate the gauges were, so I can’t say for sure.
@@valenzaplumbing There is reason 1/4 turn or butterfly valves should NOT be on pumps or systems of high flow. Most likely was valve was slammed shut while pump was running. 6" is a lot of cross sectional area.
The setup is why it broke, it's going to do it again. Someone swung on the butterfly valve handle, leverage went into the plastic. Lads, Ratchet straps to pull together, even just some ropes around a couple of times helps pull together. Washers, for the love of god, use washers.
Will definitely use washers next time. This piping has been in service for over 30 years. If someone “swung” on the butterfly valve, that’s misuse and shouldn’t happen. The pump next to it has lasted just as long and I have no reason to doubt it will last much longer. Ratchet straps are a good tip as well, but we pulled everything together pretty easily by hand! Thanks for watching!
