Hi,
our builder has suggested we don't bother with an intermediate drain test but I really don't want to destroy the new bathroom if a leak shows up on final test and would like to check it in stages.
we have just got a drain testing kit to do an intermediate test on the grey waste pipe installed to do new kitchen sink,bathroom basin and bath and loo as we want to check this is ok before laying floors. Building control have told us to do intermmediate test ourselves and they will be present for final test.
Can someone talk me through the procedure and how to detect leaks and how to seal them if they occur.
Have got 4" plugs to block off pipe in manhole,vent pipe,loo pipes,etc and some nylon plugs for sink and bath wastes. I then attach bellows/guauge to nipple on plug and start pumping air into the system? What pressure do i go to and how long do I leave it and should I be putting a smoke pellet in from the start?,etc.
the builder has connected the existing utility sink which first goes into an outside gully/trap also into the brown underground pipe for these new drains - will that effect the test or does the water in the gully act as an air stop for that section - should I be plugging that gully also despite the water.
dummies guide would be useful!
Many thanks in advance
