Toilet drain to move with hydronic in floor heating

Hi Jason,

As with most things - it really depends on where the toilet is being moved and how much work is involved. Will it be worth it if the hydronic system will need to be replaced?

We can scan the floor to see where the lines are and map out a surgical reroute of the lines but cutting or splicing the lines is not recommended due to the expansion and contraction of the lines. A connection or joint (coupling) is the a weak point and introducing one in a poured slab is not recommended.

Another option if you're undertaking a complete floor remodel is to use electric heat. If the hydronic run is local (not the entire floor) it could be cancelled and capped and a new system installed just in the bathroom. Schluter Ditra Heat is a valid option for a remodel.

I would recommend checking with a local plumber who can scan the floor and provide options that will work with your installation.

Hope this helps,

Dan

Hi Jason,

do you have picture of the waterlines before you poured the concrete?

how far do you need to move the toilet?

Thanks for the reply guys. I would like to move it 4-5' to the left. I am building a custom shower to the right of it. It's a smaller bathroom but I'm limited to where they already have the plumbing stubbed out. When I bought this house it had an unfinished basement. Don't know who the builder was. And no manifold installed yet for boiler system. So I am unable to scan the floor to determine where the lines actually lay. Would make my job a lot easier if it was.

There is equip to scan through concrete floors now. opening it will be tricky & difficult to try and break it out without damage. The hole in concrete to dig out the trap etc. & move line has to be large enough so may likely damage the hydronic lines or have 1 in the way. Not recommended without all lines scannned.
