My outside hose pressure relief valve leaks when the water is on. It comes out near the top of the valve where it connects to the facet.

I have been unable to remove it, the set screw is shot after 18 years, I can turn it about 3/4 of a turn and that is it.

Any secrets for a quick fix without having to replace the facet.

  • Can I drill out the set screw ? – bobbee25 Feb 3 '18 at 19:23

    What is the type of head on the set screw? Have you tried locking pliers (aka Vise-Grips)? Not to quibble about terminology but I think this is called a vacuum relief, anti-siphon, or anti-backflow valve rather than a pressure relief valve. – Jim Stewart Feb 3 '18 at 19:46

The anti-siphon valves I installed on my outside faucets are brass and one could drill multiple holes in the brass around the set screw to weaken it, then tear out the screw.

  • You can also cut or grind a notch in the set screw and use a slotted screwdriver to unscrew it. – Dotes Feb 4 '18 at 0:00
  • The screw in mine is bright silver color, indicating to me that the screw might be stainless steel. Of course, it might just be chrome plated steel. – Jim Stewart Feb 4 '18 at 1:07
