How to Supercede a Galvanized Water Pipe

Galvanized plumbing pipes are not as widely used every bit they once were for two reasons. The first is that plumbers have come to realize that they corrode over time, creating internal blockages that inhibit h2o flow. The 2d is that copper and plastic pipes are much easier to install and maintain.

Former galvanized pipes eventually get clogged from corrosion.

• Hacksaw
• Bucket
• 2 pipe wrenches
• Teflon tape
• Galvanized nipple
• Galvanized union
• Measuring tape

To supersede a length of galvanized piping, yous will demand a wedlock, which is a special plumbing equipment connected by a large nut. This allows you to install a threaded pipe without actually having to plow the pipe itself.

1. Shut off the valve controlling the h2o to the pipe you want to replace.

2. Saw through the pipe with a hacksaw. Accept a bucket handy to catch the h2o that will spurt from the pipe as you cut through information technology.

3. Remove 1/two of the pipe from the plumbing fixtures it is screwed into with 2 piping wrenches. Concur the fitting with i wrench and the pipe with the other, and plow the pipe counterclockwise with respect to the plumbing fixtures. When you lot have removed this half, remove the other half in the same manner.

4. Inspect the fittings to which the piping was connected for signs of corrosion and supercede them if they no longer appear serviceable. If they are not damaged, screw a 6- to x-inch length of galvanized pipe, called a nipple, into one of them. Wrap Teflon record effectually the threads on 1 end of the nipple and screw it clockwise into the plumbing equipment. When you can no longer plow information technology past paw, tighten it with a piping wrench. Hold the plumbing equipment steady with the other wrench while yous exercise this.

5. Wrap Teflon tape around the other stop of the nipple and spiral on a galvanized matrimony. This fitting has 2 female ends joined by a large hex nut. When the spousal relationship is installed, measure the distance from the border of the nut to the ends of the threads of the fitting to which y'all will attach the replacement pipe, using a measuring tape. This measurement will tell yous the length of pipe you need.

6. Unscrew the hex nut on the union and remove the half that comes loose. Screw it on to one terminate of the replacement piping, subsequently wrapping tape effectually the end of the pipe, and tighten information technology with a wrench. Wrap tape around the other end of the pipe and screw it into the plumbing equipment in the water line.

7. Fit the stop of the pipe with the one-half of the marriage attached to it into the hex nut on the union, then tighten the nut with a wrench.

8. Turn on the water and cheque for leaks. If any fitting besides the union leaks, turn off the water, unscrew the union, and tighten the leaking joint. Screw the spousal relationship back together and turn the water back on. If the union leaks, tighten the nut with a wrench.

Tip

It is possible to replace galvanized steel pipage with copper. To do this, use a dielectric union at each steel/copper joint. This is to forbid corrosion produced by the electric charge that these dissimilar metals produce when touching each other.

Warning

E'er use two wrenches to tighten and loosen galvanized joints. If yous don't, yous can inadvertently loosen a connection at another point on the water line.
