We will need to tunnel and run plumbing lines from the pool equipment and water source to the pool. We do not include any landscape, water line or concrete repair in our pricing. We will do our best to be prudent and careful. We can have lines repaired and rerouted at a nominal cost. If your yard has rear sewer, septic, well or other underground obstacles, we need to know about it in advance. These items are rare in newer homes, but if there is any question, you may hire a locating service to locate these lines before we begin.
