I recently replaced the two 30' lengths of 1/8 ID vinyl tubing that runs from my inground pool/spa to the air switches for the spa blowers. The old ones had cracked and leaked so the switches would never activate when you push the buttons. Everything worked fine for a couple days but there are 2 things that are happening that have me baffled. First, I have had 3 random turn-ons of the blowers so far. Nobody around, pool not in use, etc. Second, the push-buttons seem to lose their ability to activate the switches after a couple days and I can easily resolve the situation by going to the switch, unplugging the tubing, plugging it back in. It almost seems like I need to periodically equalize the pressure in the airline (which makes no sense). Sorry this is short and may lack info but my previous 3 attempts to post with full data have failed for one reason or another. Any help would be appreciated.
