Separate rusted galvanized pipe by heating with a torch, applying a plumber's candle, tapping with a hammer and turning with pipe wrenches. If necessary, place a length of pipe over the handle of the pipe wrench to increase torque.Know More
Use a propane torch to heat the joint. The expansion and contraction helps to break through the rust.
While the joint is still hot enough to melt wax, rub a plumber's candle around the intersection of the two pipes. As the joint cools, it draws the wax into the joint, providing lubrication to reduce friction from the rust.
Hit the joint with a hammer to help loosen the rust.
Attach a pipe wrench to each of the two pipes that have rusted together. Hold the pipe stationary, and turn the fitting counterclockwise to loosen it. If the pipe refuses to budge, use a larger pipe wrench or apply more leverage by placing a length of pipe over the handle of the wrench. If the joint does not loosen, heat the joint and apply more wax. Continue the process until the joint breaks free.
To solder copper pipe, polish the joining surfaces, apply the flux, heat the joint and apply solder. Each joint requires a few minutes to complete, but the time for the overall project depends on its complexity.Full Answer >
The three most common causes of a leaking overflow pipe are increased water pressure, an overused washer or a faulty float valve. It is important to fix a leaking overflow pipe immediately, as it can lead to structural damage to a house and mold formation.Full Answer >
A homeowner can find a sewer pipe in his yard by contacting the local sanitation or sewer district and determining where the main sewer line and connection is or by contacting a prior contractor of the home. It is also possible to dig in different parts of the yard to find the sewer pipe by trial and error, however, this method is inefficient.Full Answer >
A pipe offset is calculated when a pipe is altered in both the vertical and horizontal planes of a piping system. This type of occurrence is known as a "rolling offset." Following Pythagoras' theorem, the first number, or true offset, is calculated by taking the offset squared and adding the rise squared to obtain the true offset squared. Take the square root of the answer to obtain the offset.Full Answer >
