Here is a picture of my current setup.
I installed the Hayward Tristar VS pump last week. I got a robotic cleaner today. I have now turned off the circuit breaker for the high pressure pump. The third pump is for the "water fall" - it's just a small bar type that is on the back of a plant-a-box. The ball valve is in the fully closed position, but the amount of water it lets through is the right amount for the water fall. My plan is to consolidate everything to be run off the new VS pump. We have never used the water fall to date (only owner the house 3 months) but could see turning it on occasionally when friends are over. My intention is to install a DE filter along with an SWG before summer.
I had the water tested the other week by a pool shop and the CYA (150ppm) and CH (450ppm) was high so my thinking is when I convert to SWG, I would also drain the pool about 75%. I wanted to solicit some feedback on how to consolidate the plumbing. This was what I'm currently thinking.
1. Cap the high pressure outlet (Outlet 3 in photo) at the pump area and also install some sort of cap on the high pressure fitting in the pool so that the line will not contain any water.
2. Use a 3-way diverter to combine the two inlet pipes and route it to the VS pump.
3. Use a 3-way diverter to diverge the water through Outlets 1 & 2.
4. Use a 3-way diverter for the water fall.
Any feedback and ideas are greatly appreciated.
