Wilkins question that got emailed to me sent the following ~
My 975 xl just dumps out water out the bottom vent. I replaced the ball valves today due to winter cracks. I cannot figure out why the water just pours out the bottom. Does it matter that one of the test cocks is not facing up? I could not get a tight fit and in order to do so it is off center and facing at 9:00. Otherwise I took the check covers off and nothing seemed amiss.

Personally, I don't look to do repairs on frozen RPZs, on account of the strong possibility that the brass castings may be warped.

Wilkins 975XL

They installation should not matter. It sounds like you have a cracked seat on the #1 Check Valve. Or a faulty relief valve. Try to flow water through the backflow and see if it stops. If it stops leaking out the relief valve it is something in the #1 check valve.
