Off season upgrading

Irrigation supply store may have it as well but there is another option that may work.

If you can run 2 - 2" pipes, one for the main drain and one for the skimmer, the effect is the same as a 2 1/2" pipe although probably a bit more expensive. This is actually a better option since you can put ball valves on each run and control the suction between lines. Can you get to the main drain separately or is it conected through the skimmer? If it is connect through the skimmer and you can get to it, you could break the connection, cap the skimmer side and connect one of the lines directly to the main drain.

Otherwise, you could just go with a single 2" line as that will provide most of the benefit.

This being an inground pool the main drain suction line goes thru the concrete at the equipment pad and then underground directly to the main drain. Replacing it would be major concrete tearout and digging 10 feet down because main drain is in the deep end...9 ft.

I was lucky with the suction line to the skimmer as it was a separate line and run along side the concrete deck edge and simply covered with decorative pavers. So I only had to remove a 3X3 section of concrete and dig a hole right at the skimmer to remove the piping attached to the skimmer box.

Separate ball valves for the main drain and skimmer is no problem at the equipment pad and definently in the plans for the repiping job.

Last season (with main drain and skimmer both 1 1/2 in. PVC) normal water flow operation was 100% open flow from skimmer and 75% open flow from main drain.

This setup seemed to give good circulation in the deep end and good skimmer operation to keep surface clean.

Try a plumbing supply house such as Ferguson Enterprises, INC.
