Perma-Loc Tubing Tee Flush Valve

These Perma-Loc flush valve fittings are configured on a hose tee with a Perma-Loc one-way valve on one leg, used for automatic flushing of the tubing at the beginning and end of each irrigation cycle. At the system start up, the flush valve is open allowing water to flush through the tubing as air is expelled. The valve then automatically closes once the system's pressure begins to rise to it's standard operating pressure. At the system shutoff, the valve opens back up allowing water to drain from the tubing. To minimize the risk of drip irrigation or micro sprinkler clogging due to low water quality, it is important to periodically flush your irrigation system. If your irrigation system needs to be flushed more frequently, this Perma-Loc automatic flush valve makes this task effortless.

About Drip Depot Perma-Loc Drip Irrigation Fittings:

Perma-Loc fittings are heavy duty reusable connectors, adapters and fittings for all your connection needs. They are very easy to use and require no special tools. Perma-Loc fittings are available for both Tubing and Tape. The Tubing connectors can be used on blank tubing as well as drip line.

  • To use: Simply push tubing or tape over barbed end, then hand-tighten locking nut over tubing or tape for a permanent secure fit.
  • To Remove: Just loosen locking nut, pull tube off and re-use as needed.

Perma-Loc fittings look similar to traditional flange and locking nut plumbing connections; however, in most cases, they work differently. Unlike a typical locking nut, which comes off the fitting and slides over the tubing, a Perma-Loc locking nut is usually not removed from the fitting. The exception to this rule are some of the larger 3/4" and above tubing fittings.  Select a video from above to see how the Perma-Loc drip irrigation tubing and tape fittings work.
