I'm in the process of replacing the vaniety and re-tiling my bathroom floor.

I pulled off my old vanity and found my two supply lines stubbed up through the floor (which I expected). What I didn't expect was the 6" pipe tack-welded to the supply lines along the floor. It appears that the pipe is providing some support for the supply lines and valves.

Do I need this support? This pipe makes it difficult to put tile in the area.

The sink is feed directly from a main in the basement. This sink is on the first floor. The pipe length from the main (in the basement) to the shut-off valves is approx. 2.5'.

I haven't run across this configuration before, however I do not have a lot of plumbing/bathroom renovation experience.

Thanks for the assistance.

 

If there will always be a vanity there I would just fill with thinset or what ever you are using. Maybe put some tape around the pupes to prevent a reaction from the adhesive.

I am sure somebody will have a better idea, but they will both look the same from my house---and yours too.

 

Interesting situation. You must have galavanized piping if the 6" is "tack welded" to the lines. If you feel it is not needed, remove it. Check first to make sure it isn't holding up the main also. Good luck.

 

I'm kinda like, its covered with a new vanity. Unless you have x-ray vision, it will never be seen.

I'd hate to cut it out and then some creaking noises from below, coming from old pipe under pressure. It could be a bad day.

Joneq had the idea with thinset. Just make sure your vanity is properly level along the floor where you can see it.

Good luck, your plumbing, do as you see fit...

 

Good question.. the pipes are copper so I guess it can't be tack welded.. perhaps it is glued?? It does look like a weld but is difficult to access (see) but it is defintely attached.
