Just want to thank all you folks for coming by and reading about our problem. I can appreciate the head scratching that's going on, been doing a far amount of that myself!

I have suspected the vacuum has drawn a plastic piece from one of our grandchildren's toys into the line causing it to catch and hold stuff clogging up the works. The underground line comes out of the pool for about 25 feet and then makes a 90 deg. turn to head to the pool house. This is something that was probably done 7 + years ago. I am unable to get any kind of plumbing 'router' to make the 90 deg. turn so I'll probably dig up the area at the elbow and replace it with two 45 deg. fittings. At least then I'll be able to 'rod' out the line if needed.

As before, this is our first experience with a pool of any size. When we opened the pool this spring (we were late so the pool guys really got in my wallet to get everything clean) I found more than one FROG in the strainer in the pool house at the pump! ! ! Obviously it was really drawing water then!

So, thanks again for pondering our situation and thanks for a great forum. Dust wouldn't billow from my wallet every time I open it if I'd known all this beforehand. And to think, the guy at the pool place was offering to come by and 'service' our pool each week for only $150 a month! I do have to admit though - it was his mention of borates that got me to looking and led me to the pool forum. :-)
