Can I Replace Drum Trap with P Trap?
Hi there! My house was built in 1960 and has a slab foundation. I have removed the old master bathtub that I plan to replace with a shower. I have a couple of questions concerning the drum trap on the floor next to the master tub. First, the drum trap is so close to the bathtub that the new style showers are considerably larger and would mostly cover it up--so what are my options? What happens if I just cover it up (is that a stupid "girly" question? He he) Is it difficult to replace it with a P trap (I had read similar postings concerning ventilation)? The other concern was that there is no visible drum trap in the front bathoom--does the drainage from the other bathroom tie into this trap, or WHAT? Do I need to be on he lookout under a cabinet for another drum trap?
Thanks, Kristin. |

Hi Kristen:
In my experienece with drum-traps you will usually want to replace a drum-trap for a drum-trap. Most of the systems using drum-traps do not have individually vented fixtures which is OK with a deep/wide drum-trap but a p-trap could end up getting siphoned and that could allow sewer gasses to enter into the home creating a health hazard for you and family! If you can find a vent associated with the drain then you could definitely swap out drum-trap for a p-trap... :) It is certainly not a bad idea to relocate the drum-trap. You could install the drum-trap so the cleanout is faced up and accessible through the floor (access plate) or in a closet behind the tub. I'll need to know what the pipes are made of to recommend the proper fittings/clamps for this job. A shower will require a 2" pipe so if you have an 1.5" pipe under slab you will need to increase the pipe just before it enters the shower pan. Just FYI PS: If that tub ever drained slow, when you have the drum-trap removed take the time to SNAKE the drain line now as it is simply very easy to do so now. If problem is present you want to know NOW...not later. Let me know more... MARK |

Hi, I have a large crack in a cast iron waste line. The line at that point serves just the kitchen sink and is vented to the roof.

I am in need of some suggestions. I just tore out my 82 year old upstairs plumbing to my bathroom. I have converted over to copper plumbing and want to finish with PVC drainage.

I have a drum trap attached to the drain beneath my bath tub. It's easy to get to in the basement. Never had any problems with it, but the cap is really corroded - it has about a quarter inch of green gunk all over it. I'm going to be replacing the waste line from the tub soon, so I was wondering...
I have a drum trap below the bathtub that's leaking. I have complete access to it in the basement. It looks like the bottom of the trap, where you would crank on it with a wrench, is corroded and that's where the water is leaking from. Does any place sell replacement parts for these or am I stuck...
Hello, For the second time in a year, our bathtub drainage has become very slow. After the first incident, the plumbers snaked the line, which helped. Now, about a year later, the same problem persists, and a new plumber has told us we have a drum trap that needs to be replaced with a P trap. ...
