3 Types of Multiport Valves and Their Uses

Multiport Valves

Multiport valves are essential components of a swimming pool filtration system. They help regulate the flow of water in and out of the filter, and they can also position the valve to carry out different functions, such as backwashing, rinsing, and waste disposal. This blog post discusses various multiport valves in your swimming pool filtration system.

Types of Multiport Valves

There are three main types of multiport valves: top-mount, side-mount, and push-pull. Each type has its unique features and benefits.

Top-mount valves

Top-mount valves are the most common type of multiport valve. They are mounted on the filter and connected to the piping system. Top-mount valves have six or seven positions controlling the water flow, including filter, waste, backwash, rinse, closed, recirculate, and winterize. They’re straightforward to install and easy to operate.

Side-mount valves

As the name implies, side-mount valves are mounted on the side of the filter, making them ideal for tight spaces. They’re commonly used for large commercial and residential swimming pools. Side-mount valves are known for their durability and longevity. They come with six positions: filter, waste, backwash, rinse, closed, and recirculate.

Push-pull valves

Push-pull valves don’t feature a multiport design but are still commonly used in swimming pool filtration systems. They’re economical and easy to use. The valve can switch between the filter and waste positions with a simple push or pull on the handle. Push-pull valves are ideal for small residential swimming pools or above-ground pools.

Other than these main types of multiport valves, some specialized valves are available in the market, such as ball valves, butterfly valves, and slide gates. Each valve has distinct features but is not commonly used in swimming pool filtration systems.


Choosing the correct type of multiport valve depends on pool size, budget, and personal preference. Whether installing a new swimming pool filtration system or replacing an old one, understanding the different types of multiport valves is essential. By knowing the pros and cons of each type of valve, you can make an informed decision and ensure efficient and effective pool water filtration.
