Hayward VS700 - Suction Side Leak

[Apsuhead]

I just got a new pump and lots of PVC replaced after a winter disaster …

Pump and PVC Melted under Blanket w Halogen Light during TN deep freeze 2024

I live near Nashville TN and I keep my pool running and open all winter. It looks like we will have prolonged periods of well below freezing temps starting Monday. I survived the major freeze a year ago but I never lost power. Hopefully there is no ice or freezing rain, and it’s just snow. My...

Now my new pump has slight air bubbles coming into my skimmer basket. When I pour water over the top of the pump filter basket lid (especially the back) it seems to stop the air bubbles. Any advice on how to fix this? Thanks!

Try lube. My guys didn't use any at all when they built my pad.

That's a sign that there's a leak at the lid o-ring seal.

Shut down the pump. Remove the lid. Determine which surfaces the o-ring seats on (there will be 2). Make each surface completely clean by wiping with clean towels. Verify no significant scratches or warps. (If there are, you may have a warranty claim.) Clean the o-ring itself by pulling it through a clean rag or paper towel until no black shows. Lube the ring with a layer of silicone grease. Alladin Magic Lube II is the gold standard. Put the lid back together with an energetic twist.

See if the leak is gone. If not, get warranty service for your new pump.

It may also be that the water from your hose poured over the suction side drain plug, which could also cause what you're seeing. Make sure it's lubed and tight.

I removed the lid and wiped down the rubber seal and lid. I couldn’t tell if the rubber ring could be removed? I lubed it up and filled w it water and started up the pump again. Still getting air bubbles. Poured water over the lid and it seems to stop the air from coming in

Welp. One nice part about hiring someone is that this is now his issue.

Looks like it may be coming from the top. It was wet when I went out today. I’ll call my PB tomorrow

PB came out today and and the pump is running perfectly with no air in the basket.
