I have registered in the past - some years ago when I ordered kits. But I usually just read all the advice. Now I have a problem. I used all the information about clogged pipes last year. Blowing forced water and/or air from the skimmer side then the filter side. Both skimmers are almost completely clogged. I had the leak detector company here late last year and they could not understand what is wrong -- no leaks. I need a company at this point who can tell if I have collapsed pipes or clogs and can fix it. Hopefully without digging up my concrete. I am not far from Camden New Jersey if anyone knows a good company. Most of the pool companies in the area have young gentlemen come out to open or close the pools that don't really know very much about this problem. I was thinking of calling a sewer company because they seem to have small cameras to see where the problems exist.
