I recently moved into out new home. We now been it it for about 6 months and discovered when we use the Master shower the drain smell of sewer. All other drains in the house are fine except this one. We have flushed it out with scalding hot water for 5 to 10 minutes and the smell is not there. After waiting a nother 30 minutes and useing the shower the smell returns. Our Plummer has checked the drain and it appears in fine working order. We are despertly seeking some answers to our problem. Question is the plummer still required to fix the problem after living in the home for about 7 months? If so he is searching for answers as well. We now pour bleach in the drain evertime we use the shower and cover it. This gets to be quite a hassile. Please find out what can I do to fix this problem.......

If there is sewer gas coming up. Its one of two problems.

The first is there is no trap seal. Each trap under a fixture has about 2 cups of water inside to keep the sewer gas smell from coming back up into the home. the way it works is, there is a U shaped pipe under the fixture with a vertical riser on one part that goes to the shower and a horizontal pipe that goes to the waste line. Since the U is below the pipe, it traps water and stores it so the air can't come through. There are a number of things that can cause a trap seal to fail. One of them is that the technician didn't install the trap with the right length on the horizontal branch. If it is too long, it will siphon the water out of the trap each time you use it. If he didn't put a vent on the branch for the shower, it will siphon all of the water out of the trap and you will have sewer gas coming back up into the home.

The other reason is there is no trap on the shower. Without a trap, there is nothing you can do to prevent sewer gas from coming into the home. You can find out by removing the chrome drain and using a dry stick or other straight piece of wood, sticking it down till it stops, bringing the stick out and checking the height of the water on the stick. If its 2 inches or more, you have a trap. If the water is only on the end of the stick, you don't have a trap that is properly installed. By the way, if the trap is over 24" down from the bottom of the shower, its improperly installed and you will constantly have problems with sewer gas.

Another problem happens when plumbers forget to remove the test cap on the roof of the house. When this happens, there is no vent and every time you flush any other fixture in the house, you will get sewer gas out of the shower. This happens alot. Especially with a toilet flushing in the same room as the shower. This same problem can happen when birds build nests inside the vent for the plumbing.

Your reply was greatly appriecated. However the plummer checked the seal between the shower and the to of the drain. It seem to be ok. He resealed it. Also he checked the water level in the drain and said they were enough water present for this odor not to be present. (Provided you don't use the shower the smell is not there. We stuck our noise to the drain and can't smell it.) The moment you shower and let the water run the odor is present. We have check both vent on top of the house for each bathroom and the seem to be clear. I do not know if the shower is connected to a vent. Surely a good plumber knows better. Do you have any other possable answers? We apprieciate you helping in this discussing situtation.

Off-hand I would say your problem is with the hot-water heater....the anode rod in the heater is typically made of magnesium and will transfer a "rotten-egg" smell to the hot water. Test by running the "cold" only in the fixture. If the smell is not present youve isolated your problem. erik

Once again we thank you for your reply to our problem. However, we did what you said. We ran cold water into the drain for about 3 minutes. Waited a short time..... and again could smell the smell of sewer in the room. Our plumber was here and I showed him our corrospondances concerning this. We even took a pitcher and filled it with water comming from this shower. We could not smell nothing in the water!! We went up on the house to where the vents for the system are and ran water down each them for at least 3 to 5 minutes, each drain well!! They are running freely. They are not pluged up. We check the "P" trap once again and it is holding approximatly 4 inches on water! We have a garden tub right next to the shower in question and we can't smell no sewer from it when we use it or after we use is. Neither can we smell sewer from anyone of the two sinks we have in that bathroom. In the 1st bathroom we have a shower/tub. Then we use it, we can't smell nothing. The sinks in the 1st bathroom when in use they don't smell. Kitchen sink they are no smell of sewer when in use or not in use!! We are simply at wits end. Something is wrong!! Oh.... We can not smell any sewer in where the hot water is either.

Only one that gives out a foul odor is this shower in the master bath room. And this only happens when running water hot or cold in it! Please, Please find a answer to our problem. This one is for the record books, you can't tell the world about. Make a T.V program about. Thank you for you time and expertize.

Have you tried running a smoke test will all of the vent sealed?

Possible a missed joint or a vent pipe that has was penatrated by a nail.

Im not quite sure what do you mean by a smoke test. What does this apply. Explain please. Running water in to the vents was not good enough to asure the vent pipes were open and clear? And "Y" is the smell just in that one drain?

To perform smoke testing all of the vents are sealed off and possibily the sewer connection.

Then a blower is used to blow smoke into the drain vent system.

If there is a leak in the vent system then smoke will start to come out at those points.

That leak can be from a pipe that is cracked, a joint that was not properly glued or a nail/screw that penatrated the pipe.

The vent part of the vent/drain system is dry so it does not have water in it to leak.

But it can allow sewer gases to come out.

Your last corrospondance said to use smoke to find our leak. It confuses me. We ran water in our vents. No water came into the house! We have 2 sinks and a tolet plus a nother bathtub in the same room and on the same line as our shower that smells of sewer then water runs through the drain! This is whats confusing? Why only this drain causing the problem and not the others!! Like I said earler .... "This is for the record books. Movie should be make on this one for plumbers going to school.

A crack in the pipe or joint will allow gases and smoke to excape. However if they are in a "dry" part of the system water won't come out.

For example the top of a horizontal pipe will not be full of water. And even a hose down the vent won't fill it up.

However, you could seal of the sewer connections and all of the drain and then fill the system up to where water the top of the vents are full of water.

That will probably show the leak, after a while. But it might not as there can still be very small gaps that gases go through, but liquids won't.
