We installed Brasscraft compression valves for sinks and toilets in new house. All worked well. Months later, different valves have spontaneously begun to leak. This has happened to different valves at different locations in house. Each leaked on different days, sometimes months apart. There was never an obvious cause. Normal temperature inside. All have been on cold water lines only. The valves were not all from one same lot or box. Each box was purchased at HomeDepot or Lowes.
In each case no one was using the sink or toilet. We just heard or saw water dripping from each valve. The first leak went for 2 days before detection because house was empty causing $30,000 damage.
We checked water pressure it was fine at 40. None of the valves looked defective.
What could cause a valve to spontaneously begin leaking?
We've installed alarms but won't help if no one is home.
How we stop this?
