QTY:

The Check Valve WT104 is a one-way inline valve that protects your Triple O ozone system from backflow damage. Order a single unit or a 10-pack and keep your air pump and ozone generator running safely.

Description

In an ozone water treatment system, air and ozone gas need to move in one direction only, from the pump and generator toward the diffuser and into the tank. Without a functioning check valve, water or ozone gas can flow backward through the line during pressure changes or system shutdowns, reaching the air pump and ozone generator. Moisture and ozone exposure inside those components cause corrosion and premature wear that shortens their service life significantly.

The WT104 is a compact one-way valve designed for inline installation in Triple O ozone systems. Part of the WT series of Triple O compatible accessories, it fits directly into the ozone line without additional fittings or adapters and allows service or replacement during routine maintenance without tools. The WT104 delivers critical ozone line protection at a fraction of the cost of repairing or replacing the pump and generator components it shields.

Specifications

  • Type: One-way check valve

  • Series: WT series Triple O accessories

  • Application: Air and ozone line backflow protection

  • Function: Prevents reverse flow of water and ozone gas

  • Installation: Compact inline design

Compatible with:

  • Triple O ozone water treatment systems

  • Compatible air and ozone line configurations

  • Residential well water ozone systems

Features

  • The WT104 blocks any reverse movement of water or ozone gas, keeping moisture and ozone exposure out of the air pump housing and ozone generator.

  • No additional fittings or adapters are needed, so it installs directly into the existing ozone line without modifying the system.

  • At its price point, the WT104 is one of the most cost-effective pump accessories available for protecting components that cost significantly more to replace.

  • As part of the WT series, it is engineered specifically for Triple O ozone system configurations rather than adapted from generic plumbing parts.

  • Stocking the 10-pack ensures a replacement is always on hand for annual inspections, avoiding system downtime while waiting for a single-unit order.

Frequently Asked Questions

  • The WT104 installs inline on the ozone or air line, positioned between the air pump or ozone generator and the diffuser. Placement on the outlet side of the pump ensures that any pressure reversal during shutdown does not push water or ozone back into the pump housing or generator.

  • A failed check valve allows water or ozone gas to travel backward through the line. Moisture inside the pump or generator causes corrosion and internal damage. If you notice water in your ozone line or signs of pump corrosion, replace the WT104 before running the system further.

  • Yes. The WT104 functions on both air and ozone lines in Triple O systems. Its compact inline form factor accommodates standard ozone line tubing across Triple O residential well water configurations.

  • Inspect the WT104 during annual system maintenance. Replace it if the body shows cracking, if the internal mechanism no longer moves freely, or if you observe backflow symptoms such as moisture in the pump housing. There is no fixed valve replacement schedule, but annual inspection is good practice.
