We are members of St. Gertrude's Parish and we experienced a sewer back up in our basement. I saw BEST Plumbing listed in the bulletin and I decided to give you a try. The appointment was made between 2:00pm and 4:00pm. I received a call from our plumber at approximately 1:30pm that he was in route to our house. BEST Plumbing cleared roots out of our sewer line and operated a camera in the sewer line. They discovered a riser installed improperly, which was broken at the lateral connection. BEST Plumbing made proper repairs, placed sand and backfilled the area. Our plumber was extremely courteous, helpful, and very professional throughout the entire process. We will be BEST Plumbing's biggest fans and appreciate the service. St. Gertrude's Parish

Plumbers may not go out of their way to let you know that a toilet or sink can be moved. But if you’ve been working with them on a renovation, and they tell you something can’t be transferred to a new space, ask them to explain to you in detail why not. Speaking of things people don’t want to tell you, here are 10 things your neighbor isn’t being up-front about.
Wall thickness does not affect pipe or tubing size.[20] 1/2" L copper has the same outer diameter as 1/2" K or M copper. The same applies to pipe schedules. As a result, a slight increase in pressure losses is realized due to a decrease in flowpath as wall thickness is increased. In other words, 1 foot of 1/2" L copper has slightly less volume than 1 foot of 1/2 M copper.[citation needed]

The projects we've laid out here are particularly simple, but plumbing can be tricky, so if you're ever unsure, don't be afraid to ask for help. These projects are all pretty straightforward, but you never know what will come up, especially with older homes. We've selected some pretty good videos, but do some research and find some other videos if something about your setup looks a little different. The Internet is a wonderful thing.

If nothing inside the home was altered you should not be getting a smell. Personally I'm confused as to why the repair person would have left the original line there and ran another one through a new hole. I would have pulled the old line up, ran the new line (in PVC) and used the same hole in the septic tank instead of creating a new one. Did he seal up the hole in the tank from the old line?


For many centuries, lead was the favoured material for water pipes, because its malleability made it practical to work into the desired shape. (Such use was so common that the word "plumbing" derives from plumbum, the Latin word for lead.) This was a source of lead-related health problems in the years before the health hazards of ingesting lead were fully understood; among these were stillbirths and high rates of infant mortality. Lead water pipes were still widely used in the early 20th century, and remain in many households. In addition, lead-tin alloy solder was commonly used to join copper pipes, but modern practice uses tin-antimony alloy solder instead, in order to eliminate lead hazards.[13]
