cast iron

Hello everyone! Working on a Florida block home built in the 60s that most of the cast iron drains have been replaced in but still a bit lingering around in places we're working to replace. The toilets in the hall bath and master bath are back to back and drain into a 4" cast iron double...

Hi I am remodeling a bathroom and I noticed my cast iron pipe might need to be replaced before I tile. Should I replace this? Or should I leave it alone. This cast iron leads to the basement and the toilet and sink as well as the kitchen sink drains into it. Also, if I need to replace I am...

Hello, I have a house that was built in 1962, and we're re-finishing the basement. The current cast iron toilet flange (shown in picture), is 4-3/4" at the opening, and then 3" down it reduces to 3-3/4". I purchased an Oatey Twist-N-Set replacement flange, but it doesn't quite reach down to the...

Greetings. I have a cast iron drain pipe in the corner of my basement that appears to the corroded and getting worse over time. The lower three feet or so of the drain pipe is cast iron. The upper part is PVC. There has been no leakage or unintentional discharge up to now to my knowledge. My...

I was removing the lead seal in the cast iron hub right above the concrete slab and the hub ending up breaking off entirely. Now I have the pipe slightly below the concrete slab (see pictures). How to I go about connecting to pvc with this now? I was thinking of removing the surrounding concrete...

We discovered a leak at a joint where the tub drains. House was built in 60s and the drain lines under the slab are cast iron. Not sure what going on where the leak is.. Looks like maybe copper to cast iron. The pipe with the weird flat flange must be part of a trap - holding water. Any...

General contractor working on bathrooms knocked my stack out of alignment. This caused a leak from shower and toilet drainage. He tried to realign and tighten the connection but some tests proved this wasn’t the best fix. The stack is cast iron transitioning into PVC before it heads to each...

Hey Everyone! I'm new here and a homeowner not a professional so take it easy on me :) I'm looking to have my old cast iron radiators replaced with new ones from Paladin Radiators in the UK. Price wise even including shipping these come out quite a bit cheaper than anything I could find in the...

Hi there! First time posting here, Id appreciate any advice you can give me. Im installing a new sink in my bathroom and I can't figure out how to connect the ABS to this 1 1/2" cast iron drain hole. It looks like it's both venting and draining. I'd rather not tear open the drywall and replace...

A house I am potentially buying was built in 1955 (Florida). Given the vintage & location, the house was very likely built with cast iron plumbing. The house is ranch style on a crawl space. Sometime between 2005-2008 there was a brand new septic tank put in & then sometime between 2009-2015 the...

Today I finally caved and had a plumber replace my main 4” cast in the basement. On top of being very messy and not cleaning up, they left me with a leak. I assume they caulked this with lead and oakum. Is this the preferred method? Why not just cut it slightly before the wye and use a Fernco...

Could anyone provide an estimate to replace a rusted cast iron fitting and waste pipe? Is PVC suggested? What is the likelyhood that the cast iron runs out to the street under the house? My thought is it was likely converted to PVC when the area converted from septic to city. Any input is much...

Hi there, I recently bought an older home, and I am planning on having the basement floor repoured. Before I do, I want to make sure the plumbing buried in the old concrete is good to go. There is a slop sink in the basement that I would like to keep there. It drains into an old cast iron...

I'm a DIYer remodeling an existing bathroom. My plan is to use Schulter's system for waterproofing including the appropriate Kerdi drain. The old shower drain flange might be hard for me to remove. In large part, because I don't know how it is attached. I looked at the Kerdi Drain with...
