I have a question:
A few weeks ago, I posted that I had conducted a main drain test on a
system installed in 1996.
Since installation, this was the first main drain test performed.
The Hydraulic Calc Plaque showed residual 40 psi.
My main drain test was 15 psi.
Since the difference exceeded 10%, and there were no former main tests
to compare to, I compared to the Hydraulic plaque and wrote the owner a
letter informing them that the system may be impaired and recommended
further investigation. I recommended that they obtain the Contractors
Test Certificate since that is the only main drain we can compare to.
The owner has been unable to obtain the Test Cert.
They contacted the installation contractor and the contractor has the
As-Builts and original hydrant flow test but not the Test Certificate.
As a side note, the installation was terrible, upright sprinklers
installed 6' below roof level, upright installed as a pendent, etc. I
didnt note these on the inspection since I was just doing an NFPA 25
inspection.
What is the recommended course of action?
I don't need suggestions about NFPA 25 or liability to me (the owner is
an organization I belong to)
; What is the recommended course of action for the owner?
