Estimate costs for Toilet drain installation in cement floor?

Question

Looking for budgetary cost of a toilet drain installed in cement 18 inches from the drain line leaving the house. The house is 2 years old, the plumbing is all PVC and the entire area is accessible(no walls installed yet). This is in the basement but the elevation is 6 feet above the septic tank so I don't need pumps or anything like that. Just need the cement hammered up, and a drain cut into the pipe.

Answer 1

You'll need a vent pipe as well a toilet connection. Without the vent, the water in the trap of your toilet will get sucked out, allowing gases in the septic tank to escape into your basement. The vent pipe should go all the way up through your roof, which may be a big problem. Perhaps you could tie it in to another vent pipe in the house, but this may require breaking into the drywall to make the connection. Also, underground pipes are not always where you think they are, and so the plumber will need to run a probe down the drain to locate the pipe.

You are perhaps looking at two men for 3-4 days, which includes cutting the concrete, breaking it out, installing the closet bend (toilet connection) and vent pipe, and patching the concrete and drywall. Around $4000, including materials. It might be a little bit more if you want the plumber to run a water pipe to the location for the toilet. Be sure to get several bids, and have the bidders spell out exactly what is included in the estimate.

It sounds to me like something was left under the toilet when it was reinstalled. In which case it is a simple matter to shut off the water, drain the tank, disconnect the supply line, remove the bolts securiing it to the floor (either two or four bolts), and pulling striaght up on the toilet set it to the side on a piece of plastic or cardboard (to protect the new floor). Once it is off you will most likely be able to see the problem and fix it. If it is a loose flange or broken bolt replace it. It something is between the floor and the bottom of the toilet, remove it. Remove the wax or waxless ring and toss it. Install a new one and reinstall the toilett by lifting and setting straight down over the bolts and press down using your entire body weight if necessary to ensure that the bottom of the toilet makes firm contact with the floor. If it still doesn't then the installer must have done something prior to putting the new flooring down, call your installers back to fix it. I have a feeling that from what they told you, they did something improper and expect you to pay for it. The people that Lowe's and Home Depot uses are not necessarily given the training they need to complete the jobs they are sent on. It is sometimes cheaper and quicker to hire someone else to do it.

The tech dude has the right idea but i think he is at the very, very, very high end of the cost. Depending on the water location, look for around $400 to probably no more than $1500 for this. I do this for a living as a contractor employee and would do it on the side for cash at a much lower cost. Its actually a simple task for someone who knows what they are doing. Good luck!
