So last year, thanks to TFP, was definitely a learning experience. Luckily my brother in law lives in our neighborhood and has a pool, so he was also a good source for info.
I have a roughly 35k gallon in ground pebbletec pool. I has a cartridge filter and Polaris pump. I purchased a Polaris 9550 last summer and plan on sticking with robots, so no need for the extra pump. In addition, there is an air leak somewhere, so when I turn on the pool pump, huge bubbles come from the jet for the cleaner and after a few minutes, they turn into little bubbles, but continue while the pump is running. I've replaced the o-rings on pump and filter and replaced the air release valve on filter. The pump keeps prime, so I'm convinced that the polaris pump is the culprit.
Also, I like the clarity of the filter cartridges, but hate the cleaning and cost of new ones. So I'd like to replace with a sand filter. A local pool guy mentioned that Zeosand has the clarity close to a cartridge.
So in summary, how does the community feel about:
1) Removing booster pump from the piping and sealing any leak?
2) Switching to a sand filter with Zeosand?
Below is a picture from last year. Can't wait for it to warm up!
