• Emergency Repair Kit Prevents Cutting Plumbing Pump union gasket is a component of the hot tub plumbing system. It is a rubber or vinyl gasket that is used to seal the connection between two parts of the plumbing system, usually between the pump and the main plumbing line. This gasket is necessary to ensure a tight seal and prevent water from leaking out. It is important to make sure this gasket is in good condition and properly installed, as a leaky gasket can lead to water damage. The split nut is designed to separate into two halves when tightened, allowing the pipe to be connected without having to use additional tools. The split nut also makes it easy to disconnect the pipes if needed. ‼️ Plumbing is measured by inside diameter because this measurement is used to calculate the size of the pipe. The inside diameter measurement is the distance from one side of the pipe's inner wall to the other. This measurement is important because when purchasing fittings such as elbows and couplings, the inside diameter is used to ensure that the correct size is selected.
