In response to Re: Tapping into an existing drain
: I am remodeling my basement where a floor drain already exists. I would like to move my washing maching but I need to re-route the drain. It must go through the concrete floor and I have to tap into the existing floor drain. : Will I need to completely dig out the existing drain in order to add a new pipe? Or, is there a way to cap the existing pipe in the concrete floor w/o removing all of the cement around it? Reply: From an online code source, I believe UPC. >LAUNDRY: Standpipe receptor- max. 30in.(48in.), min. 18in.(30in.) above trap weir [804.1] [3701.6.4] No trap below the floor [804.1] [n/a] Roughed in�min. 6in., max. 18in. above the floor [804.1]< This basically means that if you want to utilize the FD for the tie-in point for the WM drain, the floor will need to be opened, the floor drain removed and the drainage and vent piping rearranged according to code to accommodate the WM. A licensed plumber should take a look at it. Good Luck & Happy New Year. e-plumber

>LAUNDRY:
Standpipe receptor- max. 30in.(48in.**), min. 18in.(30in.**) above trap weir [804.1] [3701.6.4]
No trap below the floor [804.1] [n/a]
Roughed in�min. 6in., max. 18in. above the floor [804.1]<

This basically means that if you want to utilize the FD for the tie-in point for the WM drain, the floor will need to be opened, the floor drain removed and the drainage and vent piping rearranged according to code to accommodate the WM.
