Groove floor joists for water pipes

[sebbe83]

I wonder how much I can notch the floor joists to run my water pipes. It's 15mm pipes in pipes, so they build 25mm. Unfortunately, I can't drill in the middle of the joists since they're too close (300mm), so I'm notching from the top (I know it's not optimal). The joists are 220mm, spaced 300cc, with a span of 5m. I should perhaps mention that it's a bathroom, so there will be some weight. My question is whether it's okay to just notch without reinforcing and how wide you think it can be (there are a few pipes) and where on the joist is the best to cut. Grateful for an answer

Angle drill.

I wonder how much I can notch the floor joists to run my water pipes. It's 15mm pipes in pipe, so they take up 25mm. Unfortunately, I can't drill in the middle of the joists because they are too close together (300mm), so I'm notching from the top (I know it's not optimal). The joists are 220mm, spaced at 300cc, with a span of 5m. Maybe I should add that it's for a bathroom, so there will be some weight. My question is whether it's okay to notch without reinforcing and how wide you think it can be done (there are quite a few pipes), and where on the joist is best to cut. Grateful for answers

Go ahead, shouldn't be much of a problem. You'll have the least impact closest to the wall.

Run the pipes in the interior walls? Is it a new construction or renovation?

Yes, an angle drill machine would probably work, but there will still be steel beams in the way in some places, plus I got lazy. It's a new construction. Pull the pipes in the interior wall? Do people usually do that?

If it's new construction, I would run the pipes in the furring strips on the floor below to come up where you want.
