Hi,
After winter and without the heater on, just running the pump, I found a lot of air bubbling out of my returns in the pool and weak flow. I thought I must have a leak on the suction side. Whilst investigating, I started to bleed the air using the valve on top of the filter. After several hours doing this, the air bubble seen in the pump cover disappeared, as did the bubbling at the returns and the flow returned to normal.
Today, the water was at 70 f and the pump running for a second hour. I switched the boiler on and returned less than an hour later to see a big bubble in my pump cover, but no bubbling from returns in the pool.
The heating circuit isn't on the suction side, so...?
This is the second time it's happened this season. Can you get an intermittent leak on suction side? Just seems odd both times it happened when I switched heating on after just running pump daily up until then.
Any help gratefully received. Here's a pic of the plant room attached to the cabin housing the hydrotherapy pool.
