Had to go into an attic today to do a little work.
Anyway, a new boiler was fitted a month ago, with 5 pipes running from one side of the attic to the other. To keep them level, the plumber has cut 5 holes through 2 ceiling joists, right in the middle of their 8 foot span.
The joists are roughly 5 inch by 2 inch.
Clearly, 5x 25mm holes in the middle of them is going to weaken the joist.
I was a little concerned when I saw it, but havent told the householder yet.
From my building regs book, no hole should be put into a joist at any more than 0.4x the length, so holes in the middle are clearly not allowed.
What to do?
Tell the householder, or just leave it?
I reckon an easy way out of it for the plumber is to screw some new length of wood on top of the existing to ensure their integrity.
