Plumbing Problems

09/07/2012 10:47 PM

We recently moved into a new house and have a unique plumbing problem. The toilet backed into the bathtub in the bathroom. Got a plumber to snake and somehow the problem felt solved...

A month later, now we hear some 'bubbling' sound on the bathtub when we flush the toilet, implying the same problem is imminent (similar symptoms happened earlier)

Surprisingly the toilet does not show any hint of backing up (even earlier) simply overflows into the bathtub

Is it a plumbing design mistake? I would not expected the bathtub and the toilet to be connected tied into the same drain line until it is way further into the street drain?

any ideas? we are trying to get the build plans from the previous owner.. but is MIA

Thanks

Kumar

"Is it a plumbing design mistake?"

Yes! Indeed it is.

Odds are you either have a undersized sewer pipe going out from the bathroom or a partialy plugged one or more often than not the previous owner put it in at too flat or long of horizontal run.

More than likely the previous owner had no clue how to properly plumb this and now you have inherited his problem. In addition to the previous answers I suspect that there is no vent line common to the drain, or the vent line has been obstructed by a furry or feathered creature building a smelly but otherwise safe nest.

Despite what you think the toilet and the bathtub usually share a common line if they are within the distance specified by your local codes. This line has to have a properly sized vent line going up and through your roof, the vent relieves the pressure that occurs when there is a sudden flow of water (like when you flush) in the sewer line, without it nearby openings to the atmosphere (like your bathtub drain) are where the pressure is relieved. Check your roof for this pipe, and if it's there and accessible, see if it is obstructed.

Consider your toilet habits. Does the lady of the house use a huge wad of tissue twice per sitting? Modern low-flush toilets don't always clear the line, and can leave a small dam to dry out and act as a barrier. This obstructs the flow, causing back pressure and forcing flow to the bath drain. It would back up into the sink, but the tub drain is lower than the sink. And, yes, do check for a roof vent. If there isn't one, check for an in-the-wall vent, a horrible idea. There are small snake-mounted cameras available now to check the plumbing without dismantling anything more than the sink drain.

Thanks for the responses. I will get a licensed plumber to snake with a camera, after I figure out the vent on the roof (if I have any).

Its a low flow toilet though I don't believe the 'wad' problem doesn't exist. Maybe I will have to change it to a high pressure system if I find it clogged.

Will let this thread know what I discover.

Best Regards

i think your problem is a clogged drain. do you have city sewage or a sepic tank with a leech field? tree roots clogging the drain pipe is the most common problem, but you'll need to hire a plumber that has an optic-scopic scope to pin point the problem. it will save you money in the long run.

I've seen this problem where a nappy (diaper) was the issue. A plumber managed to push the blockage out of the residential waste pipe, but it got caught in the municipal sewer feed - needed the municipal plumber to work from his end while the other worked from inside, as either could only push the offending items to the others' 'domain'. This was in a block of flats, where the upper floor tenant had caused the problem for the ground-floor occupier.

I hope the tenant got the bill for that.

The things people put down the drain.....and then not content with demanding a toilet seat in a default down position they'll toss their tampons down the loo.

Grubby really.

The plumbers worked together to resolve the issue, and both sent their bills to the owner of the block (local council). Costs would be aggregated into the following year's rent increase.

Guys, from Sleepy.

Until we moved house about 24 yrs ago we lived in a house which had regular blockings in the sewers. Fortunately this never gave us internal problems but we alway had to deal with the external ones- regularly.

One neighbour had a set of drain rods so was the expert! I provide a little brawn - so when there was a problem( the local area consisted of about 20 houses) we just got down to it.

The problem was nealy always a disposable or otherwise nappy. What people did not realise was that we could generally trace which house the offending object came from a quietword went to the householder and it did not happen again, for a while and from that house.

Why did we not have an internal problem? Simply because the interior plumbing did not allow the sewage to travel backwards and vertically up our own pipes. We picked the problem up quickly and fixed it, before it became a real problem.

Good luck with fixing yours!

Sleepy

You have received good answers if you are on city sewer. If you have a septic tank, then it needs to be pumped out. You can buy anaerobic bacteria to revive the system. When I was on one, I revised the drain to separate the clothes washer from the rest of the system. It drained into a small ditch outside the yard. That helped a great deal.

i seperated the grey water from the sewage line too, but i ran the grey water pipe around the tank and ran it back into the leech bed.

i have'nt had a problem in 30 years except i had a section of pipe collapse because i used drain pipe when i should have used schedule 40.
