The original installation included a single speed 2 hp WhisperFlo pump that ran at 3400 rpm. I replaced that pump with a 2-speed pump and later with a variable speed pump that I run at about 1,500 rpm. Maybe the original installer thought 3400 rpm was potentially too much and built this silly...

Correct, sktn77a — it’s a 3-way diverter valve, and that’s a regular system 3 cartridge filter. I’ve used that diverter valve only for draining the pool. I think the diverter valve could be turned like I think IceShadow was suggesting to stop the water from going through the filter and simply...

IceShadow — I was wrong, and you are correct. There is an MPV on the filter that would enable closing off water from the pump before it gets to the filter and forcing that water to be returned directly to the pool through the red-handled valve. You knew that might be a possibility. I can’t...

The red handle is a valve that can open or shut the water flow through that line, but I don’t know why. I made the mistake one year of shutting that valve, thinking it made no sense for the pump to do the work of pumping water from the pool only to return that same water without first treating...

I wonder whether anyone can explain an anomaly in my pool plumbing. The line from the pump to the filter has a T Union that returns some of the water directly to the pool return without first running it through the filter. I can’t think of any reason for returning water to the pool without first...
