I have been fighting an air leak that is showing up as bubbles in the filter basket. The valve in the picture is a 2-inch Ortega valve, but it looks different because I have attached a adapter kit so I could install a motorized valve actuator. You can see a white section of pipe in the background where I had to slightly modify the piping in order to install the new Hayward Tri-Star pump/motor (came as part of the Ikeric variable speed system).
I knew from last season that I had an air leak on the spa suction side (left vertical pipe in the picture) and I attempted a temporary fix by applying an epoxy resin. As expected, the epoxy resin temporary fix did not really work. This week I replaced the gasket inside the Ortega valve and that dramatically reduced the air bubbles while in pool suction mode. While in spa suction mode, the amount of air bubbles is 10-100 times greater.
My thinking now is that I really can't be sure - even with the new Ortega valve gasket - that I am not getting air from the spa side of the valve leaking on into the pool side of the valve while in pool suction mode. So I guess it is time to bite the bullet and replace my venerable Ortega valve (wish I hadn't just spent $20 on a new gasket - oh well, it is now a spare for the Ortega 3-way return valve).
So what do I replace the 2-inch Ortega 3-way valve with? A Jandy 2.5"/2" 3-way NeverLube valve?
I have roughly 9 inches center-to-center between the two vertical pipes coming from the spa/pool. Good idea to install unions on either side of the new valve? Do I even have enough room for unions?
Thanks for any thoughts or comments.
