I currently have an old old Pac Fab Superflow sand filter (off top of my head can't remember whether its a 35 or 50). I am looking to replace the filter and the pump as its becoming very hard to keep the filter cobbled together. What is recommended to be the best sand filter to use? What about a pump? What size? The pool is approx. 27,000 gallons. The filter and pump also sits about 6 feet higher in elevation that the skimmer on the pool. It is often dificult to get a prime on it and get it going. Is there a good source for these things or is it just as reasonable (price) to purchase from a pool store.
***NOTE: I have to use a sidemount control valve....not enough height clearance!!
Also, when I purchased the house with the pool, the servicing pool store recommended that I keep the pump running 24/7 during the season. Does this sound correct or maybe just because it may be undersized? Pool Store says "everyone in this area runs the pump 24/7". With it being so difficult to get a prime even after only shutting down for a few minutes, I can't imagine putting it on a timer or turning off daily... Any and all advice is VERY appreciated!!
