I kept getting a low flow light on my SWG, took it off and cleaned it. The low flow stayed on, decided that i needed to change the sand in the filter (it's been 7 years) found a broken lateral and fixed that. Now the low flow sensor is off. Went to vacuum the pool and did not have enough suction to clean the sand in the pool, I had it even set to waste to bypass the filter. it looks like my single speed one horse hayward pump needs to be replaced. I want to get a variable speed pump but I do not know what to get. The hayward pumps are difficult to follow model numbers and i'm really not sure what to buy. I'm looking for your feedback to help me.
Here is what I have, 18 X 36 inground no deep end, it is just under 4 1/2 feet deep (24,000 gallons or 88,000 liters) no bottom drain and all 1.5 inch lines. the skimmer is 25 feet away from pump and 2 outputs (1 at 15 feet and the other at 35). The filter is a hayward S244t2 with 300lbs of sand and I have an aquarite t15 cell. All wired to 230V.
I'm near Ottawa Ontario so electricity is on the high side and only use the pool 4 months a year. I plan on adding a raypak NG heater in the near future as well.
Thanks in advance,
