6.6 Vetter House connection Testing system
2.5 bar
Description
Vetter house connection systems are used for leak testing of house
connections. Blocking work and the test sequence are normally car-
ried out from the inspection shaft or from the inspection opening.
9 The pipe test sealing bag is pushed through the pipeline up to
the main channel using the thrust hose.
9 Inflation of the pipe sealing bag is made by the foot operated air
pump 2.5 bar which is contained in the set.
9 The test sealing bag is then positioned at the exit side of the ins-
pection shaft or the inspection opening and is also inflated with
the foot operated air pump 2.5 bar.
9 The safety valve on the foot operated air pump avoids any unin-
tentional overinflation above the permitted operating pressure.
9 The thrust hose is pulled tight after checking for a firm seating
of the test sealing bag and is sealed by tightening the union nut
with the appropriate spanner.
The test set 10/20 Flex can be used for the compressed air test as well
as the water pressure test. With this set there is an additional tapered
head mounted on the thrust hose in front of the pipe sealing bag
which enables retraction of the inserted pipe sealing bag even over
sleeve displacements.
A blocking valve with a bayonet coupling for inflation, an adapter
and a test and measurement hose are supplied for water pressure
testing.
The compressed air test can be carried out with the supplied accesso-
ries according to the requirements specified in EN 1610.
