Am in the process of replacing my pump and was talking to the local Leslie's manager in regard to my Pentair Triton II TR-100 Sand Filter. I'm having trouble keeping the pressure down after backflushing. Can get it down to 18 psi or so, but runs back up to mid-twenties real quickly, like one day, then gets to 30 psi or so. He says this is way too high and I should change the sand in the filter. Just bought the house so don't know when last done. Does this sound right?
Then, the label on the filter says 450lbs sand media. Could this be right? 9 bags of sand? It's fine if it is, but seems like a lot.
Thanks in advance for any thoughts
