I bought this house with an in-ground swimming pool 2 years ago.

Never had any problems until now.

Just recently it started getting air bubbles coming out of one of the spa
input jets. I can hear some air going through the plumbing near the
filter/multi valve. I don't see any bubbles going into the main pump
filter
basket.

Look for leaks on the intake side.
Start at the skimmer.
I've seen little whirlpools develop in the skimmer
letting air into the system
especially if the water level is low.


I keep the water level high enough to keep air from coming in through the
skimmers. I can see the water flowing through the pump basket. It has one of
those transparent lids. I don't see any air bubbles coming in there. I do
hear some unusual noise near the pump. It's not coming from the multi valve
or filter. It sounds like it's coming from the pump housing. I had the
gasket replaced two years ago. So it makes me wonder why it went out so
fast.

Anyway, I think I just need to go through it and replace all the gaskets
before I tear apart the filter.

I wonder; Why is it so hard to replace the sand if it's susposed to be done
every five years? I have no idea how long it's been since it's been
replaced. How can I tell?
