Hot tub spa plumbing comprises of different tubes, pipes, and hoses connected together through different PVC connectors to ensure recirculation, heating, and filtering of water throughout the spa. The spa plumbing systems can use different diameter pipe. But 2 inch pipe is the most common one and moves twice the amount of water like a 1-1/2 inch plumbing system.

Generally, there are two types of plumbing systems available for hot tubs. The first one and the most commonly available on almost every spa is the air venture system. In this type of system, the air is drawn actually into the jets water line through one or more adjustable air control valves. However, water moves through a narrow orifice inside the back of the jet body that creates a vacuum pulling the air into the plumbing circuit.

The second type of spa plumbing system is the forced air system – where air is pushed through a different plumbing circuit which is independent of the jets water circuit. In this type of spa plumbing system, an air pump is referred as a blower – which pushes air out of the dedicated air jets known as air injectors that are usually placed lower in the spa on the edge of the seats and through a built-in air channel in the foot-well space.

Though it’s not common, some hot tub manufacturers actually keep an air blower on the jets plumbing circuit in order to boost the air at the water jet, increasing the jet output pressure. It’s referred as turbo charging of the jets.

Spa Manifold –

PVC spa manifolds come in 3-way, 4-way, 5-way, 6-way, and many more styles and types like manifold wyes, true wyes, and side outlet wyes. However, PVC made spa manifolds are specifically manufactured for the spa applications and are designed to withstand hot water temperatures available in a hot tub.

PVC Pipe Fittings –

Spa and hot tub PVC pipe fittings come in different sizes and shapes. From plugs to elbows, tees to adapters, you’ll find everything at any reliable spa plumbing supplier on the market. Check whether the PVC fittings available are impact and temperature resistant to ensure a longer life in an outdoor spa application.

Spa Suction Fittings

Different varieties of spa suctions fittings are available including floor drains, lo-pro, super hi-flo, as well as various unions and union nuts. In fact, they also come in different colors and sizes to choose from. These fittings include the actual fitting grate and fitting nut as well as gasket. Typically, silicone is used to complete the installation of suction fitting.

Ball valves and valve gate

Gate or ball valves are used on either side of the pump. It’s a maintenance feature which ensures water shutoff while performing applications without draining the spa. These valves should be left in the open position while using the spa. However, slice valves are one type of common gate valve.

Proper maintenance should be considered in order to insure slice valves work properly. Remember that, they should be left open as they have a tendency to get stuck in the mid-range.
