Rusted Toilet Flange
« on: April 14, 2019, 06:18:13 AM »
On the last trip I noticed a discoloration in the grout in front of the toilet and some random wetness around the base of the toilet.  Couldn’t pinpoint a leak though.  Once home, I disassembled the toilet and found that the metal flange, around the plastic sewer pipe, had rusted through an many spots.  It had been leaking, or at least getting wet, for a very long time.  So, toilet rebuild and hoping to find a retrofit toilet flange that will work without too much work/demolition.  I’ll try to post the progress.

Also, since I’ll be replacing most of the toilet parts, I want to eliminate the overflow drain in the Sealand Traveler 511.  I got the ball seal kit WITHOUT the hole for the overflow, as suggested.  But do I need to fill/cover the hole under the rim if the toilet?  If any water gets in there, it will be trapped.  Any suggestions?

You may need to replace the flange with a "Universal Flange Kit" *as recommended in the Sealand 511 manual) such as this https://pdxrvwholesale.com/products/sealand-toilet-universal-mounting-flange-kit-white-385310139

I recently went through this ugly repair and would caution you that the rusted flange may only be the tip of your problem(s). I discovered the issue after I felt and heard the tiles around the base begin to move. Once I removed the toilet, I soon discovered that the water had seeped below the tiles and that a considerable amount of the subfloor was wet, soft and moldy. The tiles just lifted out.  I tediously removed 3/8” deep area of subfloor and glued/screwed in a plywood floor patch on which I could remount a complete new ABS flange and drain pipe assembly that extends into the black tank below. Attached is a picture of the damage found.

    As far as the overflow holes in the toilet bowl you need to get some rubber plugs.  I got mine from Lowe’s.  I pushed them and cut of the protruding part using a razor blade.
