I was helping a girlfriend with her "new" house with some old equipment on it.. her poolsweep was rather lethargic so I adjusted her "three way" discharge valve to divert more pressure to her pool sweep supply pipe by throttling the flow to the three "oversized" supplys on the side of the pool. The problem also is/was that the pressure gauge was shot, it was half full of water/no needle on it so one of the things we did was to buy a new one, but tooo late, I guess...
Well, as we were gone to the pool store (bought a new gauge) the ****ed Tagelus filter blew out the side, basically structural failure. She seemed to get very upset and all went down hill after the failure. The test pressure shown is 50 psi (115' of head) on the filter housing . I'm feeling there's no way in **** that the pressure ever got up that high. As I recall, the pump is a 1 hp, but I don't have the model/etc. to check pump head curves/etc. I'm a mechanical engineer, retired, and had a pool for over 25 years, and understand hydraulics.
My question is this.
Do you find that Tagelus have a high rate of structural failure, even at much lower pressures? the housing is black/blown type of 'fglass and looks like it's about 1/8" thick. looks like some of the f'glass is actually exposed/flaking. Does sun exposure degrade the integrity of the shell?
Thanks in advance.
