My wife and I bought a home back in June with a pool. The previous owners seemed to not do much with it as they just had a pool guy come and that was that. Well when we bought the home, we got 3 months with the same company. I don't think they ever did much more than throw chlorine in and vacuum. They definitely never backwashed. Well I sent them packing, and have been trying to wrap my head around this business. I backwashed once and it just looked clear which seemed odd, but what do I know. Then this weekend we got 8 inches of rain, and I turned my backwash on to drain the pool some to keep it from over flowing… same thing, clear. I was preparing myself to have the filter serviced, grids replaced, etc. Today I decided to jump in feet first and just see what I can do. So today:
What a mess. It was a little tough to get a good angle to pull it straight up and over the housing, but I managed.
Chunks just clogged between the grids
Grids looked perfect once they were hosed off.
Got everything buttoned back up and put 7.5lb of DE in. The pressure is down to 16psi. I used to think that the 20 it has always been at was normal. I am also hoping this might help with our priming issue. The last two mornings the pump lost its prime. The terrible part is on Monday my wife traveled for work and I left early, so we were both gone all day and I don't think the pump ever primed
Now, I am a Mechanical Engineer by education and trade, but I would suggest that nobody pay for this to be done unless you just don't want to spend the hour doing it. The hardest part was getting the grids to mesh back properly, but that only slowed me down a few minutes.
It definitely feels good to do something your self.
