Instead of an air gap, our handyman has installed a analysis valve in the dishwasher cesspool corrupt beneath the sink, but the home ambassador says this does not accede with code. The handyman says air gaps and analysis valves are appropriately able and that alike a high-loop cesspool band can be acclimated to anticipate back-siphonage. Again, the ambassador agreeably disagrees. To us, this is a agglomeration of ambagious terminology. Meanwhile, the bodies who are affairs our home assert that this botheration be adapted in an accustomed manner. How do we array through all of this adverse abstruse advice?
