We realize are filter is too small. Also the company that installed it made is so every pipe drips water. They will not fix it. Nor do we have any cut off valves. So my husband and I decided to buy a new larger filter and add some cut off valves. Who do we call for that? I do not want to call the company who installed the pool. The 3 pool stores around us say since they didn't install the pool they can't help us. We even called a plumber but he of course said that was a pool issue not a plumbing issue. My husband is not a Mr fix it, so installing it ourselfs may be a bit much for me. I love to build but I've never messed with pipes. We have an ABG 15x30. Right now we have sand and are having nothing but trouble from it. So what do your recomend for us, and who do I call to install it?
