cartridge filter advise vacuum to waste

i have a hayward cc 1000 filter cartridge system for my 24 round above ground pool.i recently read an article advising putting a a line into the drain port with a ball valve, so that you can bypass the filter when you are vacuuming the pool to waste. this sounds like a good idea to me because it would give me the option of having the vacuumed water not go into my filter cartridge particularly when there is a lot of dirt or debris in the pool.i could simply have the water going into my lawn or my gutter drain tile while i am vacuuming the dirtiest parts. could you please tell me the best way to do this ? would i put a t ball valve at the end of the hose that connects to my pumps intake? do they make such t valves? i am looking for what type of hardware i would need and where to install it , thanks paul

Hi pberm1962 and welcome to the Pool Forum! I'm going to let someone else advise you about your plumbing issue. Just wanted to say and let you know that your post had been read. Hopefully someone else will be along later this evening who can help.

Hope you enjoy being a part of the forum!

Welcome to the forum.
Probably the easiest and cheapest is to use a couple plain Jane ball valves from Home Depot, Lowes, etc. Put a PVC Tee ahead of the filter, ater the pump, and a ball valve in each leg. To dump to the lawn just close the filter valve and open the dump valve. They do make multi-port valves for this purpose but they are sort of specialty items and not found in home improvement stores. Thus more $$$. Once this thread gets into the general forum population someone else may comment on the cost of these multi-port valves.
