Digital manometers are great for setting up boilers, but I still think the faithfully water gauge is best for tightness testing; it don't breakdown or need recalibration, other than a flush out and water top up.

Done commercial industrial. Never had one this length of time. It is a badly designed gas install for the regular commercial guys, if you have a 90 minute tightness test. Sectional isolation with purge points will always simplify testing and purging.On non domestic u may be standing around for 90 mins with u gauge tho/ reading other threads?

Completely agree. I always use my j gauge for tightness tests except when the installation is huge. Like the 23m3 job I found a few weeks ago.
You have been reading IGE/UP/1 have you not?Maximum ttd is 60 mins according to table b13.
Type of Gauge Typical Range(mbar) Typical Readable Movement(GRM) (mbar) Typical MaximumTTD (Mins)
Water (SG 1.0) 0 - 120 0.5 30
High SG (SG 1.99) 0 - 200 1 45
Electronic (1 decimal place) 0 - 200 0.5 30
Electronic (2 decimal places) 0 - 200 0.1 15
Electronic (1 decimal place) 0 - 2,000 0.5 30
Electronic (No decimal place) 0 - 20,000 5 60
Mercury (SG 13.5) 0 - 1,000 7 60
Was a biggie. No gas line diagram. Spent a day tracing, measuring, inspecting and testing that job.
Anything to spin it out :lol: :wink:
Yes I think your spot on.Testing isn't an issue if you're using a calibrated digital manometer with 2 decimal places and a gem of 0.1. Brought my test time down from 45 minutes on the j to 4.5minutes.....
