I have an older Shasta pool so I am glad I can at least get replacement parts but I had to drive a long ways to get them. The people at TSpoolsupply were very helpful and had my parts the morning I ordered them. The parts were actually for a newer model of the pop up rotation device and but I was able to take the new gears and combine them with the old parts and keep my pool working. It would have been nice to know that because I had to assemble it more than once to notice some of the parts were different.

How many BTUs does my heater need to heat a pool or spa?
The ideal BTU rating for your heater depends on your desired heating speed. A 200 BTU or 250 BTU heater is suitable for a spa or pool, while a 400 BTU heater will heat your pool and spa more rapidly.
Should I cover my spa or pool with a custom spa cover or solar pool cover if I am heating my pool?
Yes, it is advisable to cover your pool when heating it. Failure to do so allows generated heat to escape, causing the heater to work harder and resulting in higher heating costs. Consider using a custom spa cover or solar pool cover to optimize the efficiency of your heating system.
