pressure testing in kg/cmsq for pipes from ug tank to OHWT.

Dear Friend,
All pipelines are tested for strength by pressurizing them to at least 125% of their maximum allowable working pressure (MAWP) at any point along their length.
In the case of domestic plumbing lines, the MAWP is considered as 3.5 kg/cm2 at plumbing outlets i.e taps,stop-cocks, etc. Hence if you see 125% of 3.5 kg/cm2 =4.375kg/cm2. Hence you will find that most of us practice at least to keep 7 to 10 kg/cm2 inside the plumbing pipelines as far as G.I pipes are concerned.
In your case, you are mentioning from UGWT to OHWT which we generally suggest considering G.I pipes only as its a forced pressurized pipeline due to pressure exerted by the water pump and class of pipe should be C class G.I pipes. So you can safely test the pipes for 7 to 10kg/cm2 maintain pressure for 1 hour, if there is no drop in pressure then the line is considered OK, and if there is a drop then the lines are checked for leakages if any , rectified and tested again.Cheeeeeeeeeeeeeeeeeeeeeeeeeers.
