Been conducting a lot of research online and cannot find a good clear understanding for what i'm trying to do. TFP seems to be the best place for being helpful and providing honest feedback
Bought my farm 4 years ago with the pool already installed (built in 1994) Pool is 18x36 and estimated 27,000 gal. It has an Hayward Pro Series high rate sand filter, 62 GPM, model no. S-244T along with a Hayward Max-Flo single speed 1 hp pump with all pipe sizes being 1 1/2 inches. There are two skimmers at 20' and 50' from the pump. There are 4 returns, 2 on the side at 40' and 52' from pump. The stairs has 2 returns at 15' from pump. One floor drain in the deep end. No other water features installed. I had a new vinyl liner installed in 2015. From what i was told, the filter and pump was the original equipment installed in 1994. Pump and filter are sheltered from the weather elements.
1) The pump is starting to make a light noise on start-up, bearings Im guessing. With the pumps age and from my understanding, being more of an entry level one, I looking at buying new and upgrading to a 2 speed or VS pump. Having 1 1/2 flow lines restricts my options. So i would like to have some feedback on your thoughts of brand name along with pump sizing (1hp or 1.5hp ) for what i have listed above.
2) Something else i'm considering on trying. Just below my pool, I have a large area that i could run several hundred feet of black hose (drip line) and tie it into my pool pump system. The head from where this material would be is estimated about 25' below the pool pump level. If a system like this would work, how would it change the calculations on sizing the new pool pump for the above pool spec's. Lowe's and Home Depot sells this in 5/8" 500' rolls for around $45.00. Ive read online where several say this does help in increasing the water temps.
Thanks and hopefully these questions aren't to confusing
