Cutting in to beams for shower waste pipes

[shulverp]

Is it OK to cut in to floor beams to connect waste pipes to a shower tray ?And do i need to reinforce the beam ?I am fitting a new shower to a chipboard floor and guess what the waste outlet is right on or very near a beam so the pipe work will need to at last cross over the beam . The shower tray is ceramic ! Ie heavy and is a Quadrant type, with no clearance underneath for the waste.

Would be best to drill hole in centre of beam rather than notch it out. Depends on depth/height of beam and whereabouts in the span it is.

Post this info and the more tech guys on here will be able to advise you better.

Can you not raise the tray for clearance or is that a silly idea.?

You'll be using an 1.5" or 2" pipe, so you must have a monster joist for that to be posible. Can't remember the notching rules so read this:
