I have what I believe to be a 30 year old sand filter it is a Triton model TR-60 the sticker says the filter area is 3.1 sqft. The fiberglass has cracked and of course all the media was pumped out along with a few hundred gallons of water. The pump is also very old, it is a 1hp pump but is working fine.
My pool is in Orlando and 35k gallons, heavily shaded back yard. I have 10 solar panels on the roof to provide heating. The pool was converted in salt when the solar was installed in early May, a Hayward Aqua Rite chlorine generator. The pool is screened in and was resurfaced four years ago.
Pressure and flow seem sufficient, maintenance has been minimal. I have had to spend about 30 minutes a week in the peak swim season to keep the pool crystal clear and clean (we have a suction cleaner). One of the comments is that 1hp does not seem like enough power with the suction cleaner and solar heating system. When it is all running I can only pull water from two of three sources (drain, skimmer or suction cleaning port), quite honestly this has not proven to be a big deal but it would not be horrible if I could run all three at once.
Clearly the filter must be replaced ASAP, what size cartridge filter should I be considering? Most likely will buy a hayward or pentair.
Should I replace the pump? I typically live in a if it aint broke don't fix it world, but I am willing to consider replacing the pump. I don't see a variable speed doing much good considering we ran the solar heater all spring summer and fall to keep the pool swimmable.
Your thoughts are appreciated.
