I was doing more reading on laterals and it said to just replace the whole
filter is much easier. Considering the filter is 35 years old I think I'll
just let it ride for awhile. The sand amount is pretty small and it has been
doing it since I got it.
I backwash a lot too. Maybe too much. I read, on the internet, that I should
wait until it gets 10lbs over not 3 to 4 lbs like I was. I'll cut back on
the backwashing.
It really sounds to me like the air is getting in through the pump gasket. I
almost positive the spider gasket needs replacing too. I had some issues
with it backwashing into the spa.
