Good work, be aware that this is a dangerous situation, most states require a licensed boiler man to work on these.
If you were to accidentally bypass the low water cut of, and *** if the pressure relief valve were blocked with water scale, the boiler could blow up, break that gas line, and take out a city block or two***.
Tell me how long it takes for the sight glass to fill with water so that the boiler then comes back on.... then test the pressure relief valve my lifting its manual release lever to insure that it does indeed blow off steam when manually operated.
If it is running low on water repeatedly it has a steam leak, I need to know how long this has been going on. Bad steam traps or condensate return pumping systems can also cause this problem.
I need you to describe the use of the steam, radiators or heat exchangers
, and condensate return provisions.
And keep this in mind... *** if the pressure relief valve were blocked with water scale, the boiler could blow up, break that gas line, and take out a city block or two***
Your building owners liability insurance might not cover such damage, it would be a nightmare for all concerned.. especially for those people and family members killed in the blast.
