Here is my equipment setup:

- Pentair Dynamo 1.5hp 2-speed pump
- Sta-Rite System3 cartridge filter (300sq/ft)
- Jandy Lite2 250k BTU NG pool hater (millivolt unit)
- Jandy check and 3-way valves
- all 2" plumbing from the pool to the equipment pad and at the pad
- three 2" lines installed and one 3/4" line installed for configurability

I plan on adding a 15gallon chlorine tank with Stenner pump in the future along with possibly a booster pump and pressure cleaner or a robotic or vacuum cleaner. I am installing dual main drains to comply with code and to remove any concern about "entrapment".

I talked to a few people and if you have good circulation in the pool with plenty of turbulence at the bottom the main drains are supposed to do quite a good job of minimizing vacuuming. I figure for the minimal expense (I am doing the complete install myself) it would probably be worthwhile.
