I'm installing a 5-zone drip irrigation system. I'm locating the control valves in my garage, whose walls are concree block with brick veneer on outside.
The poly pipe is 0.700" OD.
Rather than drilling five separate holes through the wall, I want to drill a single hole through the concrete block and veneer. The size of the hole needs to be large enough to accept a sleeve of 2" PVC (to protect the poly pipe and to allow for winterization).
I have a complete set of bi-metal hole saws, but none for cuttng through the concrete block.
Any recommendations?
