    How to cap toilet flange

    I will be not having a toilet in place during remodel and it may be days/weeks in that state depending on how things go etc so I was wondering about the options for capping the toilet flange during that time. I spoke with the guys at the supply house and they don't really have a cap for this. I'm wondering if I could cut off the old flange and cap the drain since it is likely the level of the new toilet will be different to the old one and so will probably need a new flange anyway.

    Any ideas?

    Be careful stuffing some rags in the pipe that you don't lose them.
    Yes, they shouldn't travel far but why take the chance.

    while that might be fine for keeping debris from falling in, it will not completely seal off sewer gas and if you get a stoppage, you wished you spent the $4.00 for an expansion plug.

    in the old days we called these dollar plugs. now with inflation we call them $4.00 plugs.

    Rick,

    While doing remodels, I usually stuff some rags in a plastic bag and shove it in the pipe. Comes out easy enough and you just toss the bag when done.

    I've created a product to solve this issue, visit my site at TrapCap.com, or find me on Amazon.com, search for Toilet TrapCap. Lockout and seal the toilet flange while the toilet is removed or uninstalled during construction

    Correct me if I'm wrong. A 3x4 hub (female) abs closet flange, which is approximately 4" od can be solvent welded into a 4" pipe. A 3" abs male pipe size closet flange" which is approximately 3-1/2" od, will not.

    Okay I think I get it and that's a great solution if it works - pull the spacers finish the floor with the new extra sub-flooring and tile cut to support the new flange and then glue the new flange down as the final step into the old flange. I will get the flange and dry fit/experiment first. It's going to be a little while before I need to get to that stage anyway as I need to finish tiling the lower section/pan of the shower first.

    I'm in the Scripps Ranch area of SD which is about 30 miles from Carlsbad where Legoland is.

    The 2 white spacers look to be just sitting on the flange. Normally they need to be siliconed down.

    Remove the spacers, clean the wax and the inside of the abs pipe where the new ring will glue down. Do a dry fit first. The flange is suppose to sit ontop of the finish surface/ tile floor.

    Went to Palm springs and the snow ontop the tram at 8200'.

    How close is legoland to you?

    Rick.

    Post a photo. A 4" diameter closet ring is very common out here with new construction plumbing.

    Buy a common 4x3 wax ring and you'll be good to go with no problem.

    Post a photo to be sure. Hd has the 3" ring there too.

    Hey Rick - did not see you posting recently so I guessed you might have been on vacation.

    Here is a photo. So are you suggesting leaving everything as is and gluing the new flange on top or removing those spacers first. Do the spacers just pull off or are they glued. Can I just glue a small section of pipe first if I need to raise the new flange to the new floor height.

    Is the install shown in the photo correct or should the bottom of the flange be sitting on top of the tile with the tile and sub-floor supporting the flange?

    Did the vacation involve Zip lining in Utah ?

    Ahh, got you. Tape that darn pipe cutter to the drill. I would open the ceiling though.

    I've yet to remove the tile and backer around the flange but I think it may still be too low to cut from the outside so I was thinking I would need an internal cutter (unless I open the ceiling from below)

    Okay so I pulled the toilet today. It looks like the original flange was set too low and it looks like they have used at least a couple of spacers to get it to the correct height. The wing nut cap suggested by tool worked great for capping. The drain turned out to be 4". Plumbus - my home is about 15 years old so all the drains are ABS. So anyway it looks like I will need to cut out the original flange (I guess using an internal pipe cutter), add a riser (I assume using a coupling) and then cut to size once the new floor is ready as suggested. However, is there a risk that doing this way might end up needing to cut the coupling rather then the pipe in which case how will the new flange fit.

    Can anyone also guide me on the use of a wax vs non-wax ring. The original install had a wax ring. Also any tips on cleaning off the waxy reside off my putty knife that I used for scraping it off?
