Two small water leaks have been found on ITW High active water system. One is from an unused 1/4" copper valve stem. another is on supply 1.5" supply line valve body top sealing. Both of them are seeping water from seal. 1/4" copper valve will be replaced with a new one. 1.5" supply line valve will be replaced by an old valve with all new seals. I have all spare parts in hand.  At present, water supply to ITW are stooped to reduce leak rate. Two aluminum flat tray are put underneath leak valves to hold small amount leak water. Both leak will be fixed in April  mostly.
