Dear K.Din
Is very difficult to explain to Mr. Dave to understand the system
Like ICSD. that in site valve box but not every valve
actual 12" valve box we do for all lateral line valve
and 10" round box for main gate valve
but some 12" valve box have to replace by 10" round box following Mr.Ali request
How to tell Dave to understand
if you ask me i will ask Dave for an as-built and mark for him.
If anyone have any solution please let me know how to explain to Mr. Dave
Best regards.
