my family is about to move into a home that has an in ground pool with a liner and a hot tub. the pool has not been maintained in a decade or so and we know we have a lot of work ahead. the land also has a spring on it that is flowing quite a bit. I have read some other questions and answers on this subject but I have an idea about it. so to divert the spring to the pool is easy enough so I wont go into that but I read that the water turnover in the pool may be a problem. if there is a drain at the deep end of the pool that is constantly pulling water from the low point and the pipe is vertical to just under the water level it should equalize and always be flowing. also at that connection is a T and another drain pipe with a valve at the end to use as the vacum line. can anyone see an issue with this? of course as long as the water is acceptable to use in this way. thanks for any input.
