Hi all
Today I'm drilling a hole in the plastic cold water cistern in the attic as well as a hole in the dhw copper cylinder in the airing cupboard.
This frankly terrifies me...so can you share you tips about how not to **** it up please?
I.e. drill bit to use, how fast to drill, any other tips.
The hot cistern cut is to fit an Essex flange (well, a techflange side entry). The Essex is supplied with the appropriate holesaw, but it would still be great to get advice on RPM and any other tactics to reduce my chance of calling this up.
The background is that I'm fixing a bodged shower pump installation, the installer teed off inappropriate places rather than running dedicated feeds. I'm guessing his was cause he didn't fancy drilling cisterns either!
Many thanks, much appreciated.
