making holes in the joists to run pipe
 
Hi everyone!

I am planning to put a bath tub in bedroom. the house has joists going in wrong direction. plumber said he will have to make holes in the joists to run the pipe. is it a common practice and is it safe? would the inspector have any problems with this?

Also, some of the plumbers that looked at the job should replace the old pipes and old vent .... but most said i could use current pipes. What is the right thing to do?

thanks

I'm by no means an expert, but from what you've said, it is common practice to run the lines through the studs/joists. They have to make it to the final destination somehow. As far as the pipes, I guess it's a matter of cost and the condition of the current pipes...

Drilling holes is normal, some rules apply, a plumber should know these rules, we use existing plumbing all the time, if in good shape, replacement of old pipes can get costly, your decission.

If the pipes are copper i would keep them. If there galvanized i would consider having them replaced with copper. Galvanized pipes will corode on the inside if there old.

Is there a maximum size hole you can drill? ie. 1/4 of the joist depth....1/3 of joist?
