1. Always use KiTEC test plug(see figure) for plugging the female threaded open ends.
2. Hand tighten the test plug inside the female threaded fitting. The seal of test plug will ensure sealing of the end.
3. After testing, test plugs should be replaced by plastic threaded plugs. 4. Follow the test procedure as given below.

1. Never use GI/MS threaded plugs. Over tightening of these plugs for achieving sealing at high pressures may weaken or damage the fitting.
2. GI/MS plugs should not be used for normal plugging also. Corrosion of these plugs over a period may lead to weakening of fittings during removal.

Test Procedure
The whole installation should be tested hydraulically on completion by subjecting all supply and distributing pipes, fittings and connections to appliances, to an internal test pressure of 1.5 times the maximum operating pressure for the installation or the relevant part.
the whole of the system is subjected internally to the test pressure which is maintained by pumping for 30 minutes, after which the test continues without further pumping.
The pressure in the system is carefully reduced to one third of the test pressure
The pressure does not drop over the following 90 minutes and there is no visible leakage;
