I got the new pump (Hayward Matrix 1 hp, 2 sp) and filter (Hayward S220T sand fiter) all connected. All hoses on as far as they can go and all hose clamps are tight. I have one small seeping kind of leak where the hose going to the filter connects to the top of the pump. I am working on that one tho not quite sure how to stop it as everything is as tight as it can go.
First, the manual says the pump is self priming. YAY! But, I have read on here that small bubble = good, BIG bubble = bad. Well, the lid over the pump basket is domed. How in the world do I achieve a "small" bubble? Currently the pump is not bolted down. So, I have carefully tipped it back to work the air into the hose and burped it thru the skimmer before turning it on. Shouldn't do this, I know. And cannot anyway once it is bolted down.
My other (and main concern) is, the bubble grows. I started with a small bubble, a bit larger than a silver dollar. After 5 hours on HI, the bubble was almost as big as the clear dome on top of the pump lid. I switched to LOW and ran it for 3 hours and the bubble did NOT get any larger.
Oh, I did lube the O-ring on the inside of the lid. Could it need more lube?
Could the small leak from the pump to the filter be causing this? If so, how? The leak is after the strainer basket, at the point of exit from the pump. If not from this leak, any ideas? I haven't waited to see if the bubble gets any larger on HI. I'm afraid it'll cause problems if it gets larger. Am I being paranoid?? Is the pump designed to have a bubble the size of the clear dome? Is it self balancing the air? I mean, realistically, I cannot bleed air out of the domed lid once the pump is bolted down, so is that large a bubble part of the design?
