5.4. Perform function test
1. Rinse pipe
2. Close valve (clockwise).
Only a gentle turning is needed to close the valve.
Tightening with too much force does not improve
the sealing, but can rather cause a malfunction.
The water in the pipe must drain out.
3. Open water supply and check the valve for leaks and
function.
After closing the valve, a small amount of water conti-
nues to flow, because the valve empties by itself.
Remove hoses and screw connections before the
frost period.

ment or the sewerage system!
