I am in the process of planning to do an equipment upgrade of our pool. We bought our house about 2 years ago, and it's been running fine, but we'd like to change out the WhisperFlo filter pump to a new Pentair variable speed pump (e.g. the new one that ends with "18" in the product number. I believe the pool may be over 20 years old (the house was built in the late 60's), but the equipment was changed about ten years ago (based on what is there). When the equipment was changed, they did not apparently attach the bonding wire from the pool shell to the pump or heater, and I cannot locate it. Also, the two color changing SAM lights do not appear to contain bonding wires, only grounding wires (these are both 120V lights). Fortunately, nobody has experienced any sensation of electrical flow in the pool (perhaps because all of the plumbing in the pool is sch 80 2" piping).
Thus, my question is how I should proceed? I will try to dig around the equipment pad and see if I can find the bonding wire. But, if that fails, I guess I'd have to come up with some way of re-bonding the pool. I believe both of the pool niches are from Pentair/Amerilite, and those should have internal and external bonding lugs. Would it be sufficient to run bonding wires via the lighting conduit (sch 80 PVC unfortunately) to those bonding lugs, and then run the 8 ga copper bonding wire back through the conduit to the pool light box, and then to the equipment pad? Would it be necessary to have to dig up parts of the concrete deck to add bonding wires to the re-bar (this is a concrete/plaster pool)? I'm really frustrated because the guy who lived here before seemed to do plenty of wiring but didn't seem to understand the concept of proper grounding and bonding. Any sense of how expensive this might be to hire a professional?
