I am looking for a way to regulate the amount of air being introduced by my spa blower. In my research I have read that putting a 3 way valve to divert some of the air out of the pipe (note: I am talking about diverting some of the air, NOT trying to restrict the air flow) can help dial in the air flow. My question to anyone with this setup, can you post a photo of the valve? Or can someone tell me which valve I should look for? I am handy and can put it on myself without any issues. I just need to know if there is some specific type of 3 way valve I need to look for, or just any old 2" 3 way valve will work?

I tried the Tee and ball valve.. it works pretty well and you can adjust the amount of air going to the jets. But it’s just not viable because the air coming out of the valve is WAY too loud. Like twice as loud as the blower itself, which is already loud enough. ?

Put an air muffler on the end of the ball valve. I did the same thing with the ball valve and found it noisy as well, so I ordered a $10 muffler with 1" NPT from ebay and screws right into the ball valve and makes the purged air silent.
