Some of you may have seen my Spa build thread, most probably haven't, but quick summary... I bought a used portable hot tub, and am plumbing it in with the pool, like a spillover spa on an inground without the spillover. Everything has been going well for the most part until now.
Today I tested my air buttons and ran into a major issue. My equipment is about ~35ft from the spa and where I was planning to put the air buttons to control the two pumps, blower, and light. The problem is, my buttons don't create enough pressure over the 40ft of tubing to actuate the switches. If I blow into the tube, I can actuate the switches, but the buttons just can't do it.
I COULD just move the buttons closer to the pumps and mount them to the wall of the shed. This would give them a 15 ft. run, but then you have to get out of the spa to use them and I'd rather not do that. The only other solution I came up with was to put an aux. compressed air tanks under the spa shell and use a momentary Pneumatic switch, like this one Click Here from McMaster-Carr.
Any other Ideas???
