• A hot tub gate valve is a type of valve used to regulate the flow of water in a hot tub or spa. This valve is usually installed at the point of the hot tub's waterline, and it is used to control the flow of water in and out of the hot tub. The gate valve is opened or closed by turning a handle or knob at the top of the valve. When the valve is open, water can freely flow in and out of the hot tub. When the valve is closed, no water can pass through it. The gate valve is usually located near the pump or motor of the hot tub. It is used to adjust the flow of water and control the temperature of the hot tub. Hot tubs use a heater union to connect the hot tub's heater to the hot water supply line. This allows the hot tub to draw hot water from the supply line and heat it before it is circulated around the hot tub. The heater union is responsible for maintaining a tight seal so that no water or steam can leak out. Heater union gaskets are rubber seals that are used to connect two parts of a heater together. They are typically placed between the heater’s flange and a union. They provide a secure seal to keep the connection between the two parts leak-proof and also prevent any debris or contaminants from entering the system. ‼️ 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.
