Questions on changing to a 2 speed motor on a Hayward Super II pump

Ben, I'm not sure which filter that is, I have two, I switch them out, They both used to have bands around them but they've been blown out for the last year or so and I removed the shreds that were left. One was from the local Ace Hardware store that has a pool center, the other one is one the previous home owner's pool service installed. I'll have to look at them tomorrow and see. I've not bothered to get new ones since I've known I was going to put larger filter in at some point in the near future. Now I'm ready.

I sent the pictures of the pool and spa because you requested them a couple of posts ago to help determine what I might do about the pump and plumbing. I guess you can post them as you see fit or put them with my others that you had the link for.

Thanks, Kevin

Oops. Sorry. Got threads confused -- I'm dealing with 3 similar threads!

Lemme reset. OK, re-read you thread to make sure I knew where I was.

If you want to simply put your pool on hold, till you get all new gear, we can help you do that.

BUT, if you want to USE your pool before then, do this:
1. Get a new Unicel cartridge, but do NOT install it.
2. Pipe a bypass around your filter, and put a 1/2lb spring check on the filter line, and a 5lb spring check + a valve on the bypass line
3. Then, install the Unicel. That way, your bypass line will move excess flow AROUND the filter, when it gets dirty, so you won't destroy the cartridge.

Surprisingly, Amazon has US made cheap calibrated check valves you can use. I'll post the links if you want to pursue this.

Thanks for the bypass info Ben, I've already picked up a used Jandy cl-320 cart filter to replace mine with, I"m just gong to make a final decision on ordering a new motor, or new pump and get to work plumbing it all in. The pool is functioning as is and will do OK until I can set aside a day to install the filter and motor or new pump.
