Check Valves

Hot tub check valves prevent water from flowing backward through the spa plumbing system. These valves are commonly installed in circulation lines, ozonator lines, and other plumbing areas where water must flow in only one direction.

A check valve automatically opens when water flows forward and closes when water attempts to flow backward.

Common Spa Check Valve Problems

Spa owners often replace check valves when experiencing problems such as:

  • Water flowing backward through plumbing

  • Ozonator water damage

  • Spa plumbing leaks

  • Circulation problems

  • Check valve stuck open or closed

Replacing a faulty check valve helps protect spa equipment and maintain proper water flow.
