How far is your pool from the equipment pad in feet?
How many returns and drains do you have?
What are the surfaces like from your pool to the equipment pad? ie, decking materials, patio area, grass, etc.
If you have one or more leaks in your return lines, you are going to need a company w a reputable/proven track record to fix this type of issue. Furthermore, some of the board experts here will probably recommend that all your valves, seals, O-rings, unions from PVC to equipment are all thoroughly checked and air-tight.
Finally, how long ago did you buy the house and was there an inspection of the pool? Did the previous owner disclose anything about this issue [sold "as is"] ? If not, and he knew about it, and did not disclose it, you may have some recourse. But, this depends on your sales agreement and local law.
good luck, tstex
