We bought our house with a 20x40 inground pool that hasn't been opened in 5 years. It's a complete frog pond. The filter and pump are plumbed into the basement of our house and we need to get those pipes rerouted outside to prevent any possibilities of it flooding the basement (it happened to the previous homeowner) I think I have figured out what the lines are inside and I have dug outside the basement wall and unearthed each of them. I'm not sure which suction line is the skimmer and I'm assuming the other is the main drain but I can't see the bottom of the pool to locate it. The skimmer is plugged. There is one jet on the side that is plugged. I found another possible jet hole on the shallow end of the pool that seemed much lower than the other jet and from what I could feel through the industrial strength rubber gloves I wore it felt different than the known jet. Whether this is a vacuum line- I don't know.
My question is this- I can either leave the plugs in the skimmer and jets (assuming that 2nd one has a plug) or I can drain it to just below those areas to prevent water draining when we cut the lines outside of the house. But what do I do about the main drain line? How will we be able to reroute this line without water pouring out of the tubing when we cut the existing line and try to attach new pvc to the outside of the house?
Is this something we should attempt or hire someone? We need a new pump and filter and that is going to eat up a good portion of our reserved pool funds so I'd like to do as much as I can myself. The shut off calves are on the inside section of pipes unfortunately.
Also- in this situation how do I determine which line is the main drain vs skimmer coming into the pump?
