What water control valves require you to relieve pressure before operating?
If you get to talk to an Anderson engineer - try and get him to say the ABCO RV manifold assembly requires you to relieve pressure before operating the manifold.
Internet fluff from the early days when the Anderson BRASS Company made the manifold out of almost all plastic. The plastic used could not maintain tolerances and the cartridge assembly could not maintain the o-ring in the gland.
And those manifolds were so bad turning off supply and relieving pressure was not enough to keep the O-ring in place.
