Hi there fellow pool lovers!
I have a very old (30+ years!) pentair-nautilus filter.
A couple of weeks ago I noticed a crack on top housing of theh greeds.
I went to my friendly pool supplier and they gave me a replacement.
I've been trying to open the pool for a week and the water is not getting better.
Last night I looked closely and discovered that the new housing has an extra hole. so it is not good.
Anyone knows where can I get an exsact match for this old clunker.
I include a picture so you know what I'm talking about.
The new housing is black and I placed a marker showing the extra whole.
I would apreciate any help you can provide.
