White PVC pipe is the current material of choice for most drain lines. Existing black ABS pipe can be replaced with PVC. If you use a transition fitting, you can connect PVC to galvanized drainpipe. Special fittings also allow you to attach PVC to cast-iron pipe. Using PVC for supply lines is not allowed by many building codes; check with your local building inspector before using it. CPVC is approved for many outdoor uses, such as lawn sprinkler systems. Plastic pipe is easy to assemble, but take care to do it right. Joints must be primed and glued completely or they may leak. If you install a fitting that makes a turn, such as a tee or an elbow, use alignment marks to ensure the fitting faces the right way. Mistakes can't be corrected -- if a glued joint points in the wrong direction, you must cut out the faulty section and start over. Before you tackle the real thing, practice cutting and gluing pieces until you feel proficient. About an hour to make a simple repair

PVC saw and miter box, utility knife, tape measure, felt-tip pen, PVC pipe cutter Spread a drop cloth to catch any spilled primer and glue. PVC pipe and fittings, primer, cement Cut PVC pipe using a PVC saw, a hacksaw, or most any saw with fine teeth. A miter box helps hold the pipe to make perpendicular cuts. Scrape the inside and outside of the sawed edge with a utility knife to remove burrs. Assemble the pieces in a dry run to make sure everything fits. Disassemble the pieces, keeping track of the order in which they will be reassembled. Apply primer to the pipe ends and to the insides of the fittings. The strip of primer on the pipe should be wide enough so that some can still be seen after the fitting is attached. Apply cement to the outside of the pipe, then to the inside of the coupling. Immediately insert the pipe into the fitting and give it a slight twist. Some cement should ooze around the joint. Hold the joint for about 20 seconds, then wipe away any excess cement.

Wait at least 30 minutes before running drain water through the pipes.Edit ArticleHow to Repair a Broken Sprinkler LineUsed Furniture Stores London Ky Loss of pressure, geysers, dry spots and overly saturated areas are but a few of the problems associated with broken sprinkler lines. Cheap Christmas Ornaments Balls In BulkSo cast off the yoke of overpriced landscapers, gather together courage and shovel, and fix it yourself. Hanging Paper Towel Holder IkeaYour wallet will be glad you did. Isolate where the leak is. Dig a reasonable work space around and under the break, as you will want a bit of "play" or movement in the PVC in order to achieve a rock-solid tight fit with your repair. Using purple primer and the brush that comes with it, prime the outside of both of the remaining sprinkler pipe ends by painting a 1–2 inch (2.5–5.1 cm) wide strip around the outside of each pipe end starting at the lip/edge.

Cut a piece of repair pipe to fit the length of the cut you made in the sprinkler line, minus approximately 1/2" or more for each straight coupler used (the coupler adds approximately 1/2 inch to the length of the finished pipe). Fit the cut piece into the couplers dry, to be sure that the fit is correct and that the resulting pipe is not bowed,from the replacement piece being too long. Disassemble and make any necessary adjustments, until the resulting fit is perfect. Prime both ends of your cut piece, wait 5 seconds, then apply a light layer of glue to one end of the replacement piece and inside one of the straight couplers. Alternatively, use a "repair" coupling which does not have the inside center ridge; basically an over-sized section of pipe. Alternatively, you can cut a coupling piece in half, lengthwise. Watch the area of your repair for a few minutes before you cover your hole back up. An easy alternative to bending the pipe to fit, is to use a "telescoping coupling"(slip fix is the common name) available at any irrigation supply house or Big Box hardware store.

As any nearby fitting to the leak can be cracked by bending the pipe, a "telescoping coupling" removes this problem. Instructions on how to use the product will be included. This is how the "pros" do it. Always wear gloves when working with PVC primer and glue. Consider using "wet/dry" PVC solvent (glue) versus primer. Primer can easily be over used and weaken the pipe. Never store PVC in the sun, it degrades and weakens the pipe structure. Make sure the inside of the PVC pipe that remains after you cut out the broken piece is as clean as you can get it. Even a little bit of dirt left inside can end up clogging your sprinkler heads or prevent your system from draining properly. Drying times for PVC glue varies based on humidity and temperature, longer drying may be needed. Don't get lazy when digging around the repair -- as hard as it may be to dig, you will need plenty of elbow room to work and must keep the fittings clean. As some valves will leak even when in the off position.

A good little trick is to use a piece of bread inside of the leaking pipe.This will stop the leak long enough for the repair to be made.And the bread will break down and not clog any of the lines or sprinkler heads up.Written When leaks or breaks occur, replacing defective fittings and/or pipes frequently requires only a few simple tools and readily available replacement parts.1.Locate the leak. Water can travel along the pipe a considerable distance from the source of the problem before falling as a drip. Wipe the area around the suspected leak dry with a clean cloth and look carefully for the source of the leak.2.Determine which pieces you need to replace. There is no practical method for removing PVC pipe from glued fittings. When the leak is located at or within 2 inches of a joint, the simplest repair method is to remove a section of pipe along with the adjoining fitting(s).3.Turn the water supply off to the affected pipes. If the house has an internal or local shut-off valve, use that.

If not, you may need to turn off the main water supply valve.4.Remove the defective section of plumbing. Use PVC cutters to remove at least 1 inch of piping on either side of the leak. The defect causing the leak may not be readily apparent with visual inspection. Removing a small amount of apparently sound material decreases the likelihood of the leak reappearing. Place the PVC cutters at the desired location, hold the cutter's jaws at a 90-degree angle to the pipe and make a straight cut through the pipe on either side of the leak.5.Allow the water inside the pipes on both sides of the removed plumbing to drain completely. Dry the ends of both pipes with a clean cloth.6.Loosely assemble the replacement parts and dry-fit them in position. Make any necessary adjustments to the parts before glue-up. Once all the parts are properly sized, disassemble them in preparation for primer and glue application.7.Apply PVC primer solvent to the inside of each fitting and the outside of each pipe. Use the applicator brush attached to the underside of the container lid to apply a thin coat of solvent to all surfaces to be joined.8.Start at one side of the exposed plumbing.

Apply a coat of PVC glue to the outside of the pipe and the inside of the replacement fitting with the applicator brush attached to the container lid. Insert the pipe into the fitting with a twisting motion. This helps spread the glue inside the joint and helps the pipe slide completely into the neck of the fitting. Hold the newly formed joint together firmly for 10 seconds to prevent slippage.9.Repeat this procedure until all missing pieces are replaced.10.Allow the glue on the repaired plumbing to cure for at least 15 minutes. In warmer, drier conditions, the glue may not take this long to cure. /prod...Written PVC pipe is a popular choice for residential plumbing. As per my point of view, leakages happens only if the two pipes meeting at a joint are angled with respect to each other, the joint is almost sure to leak, no matter how tight you make it.There is a time when an emergency PVC joint repair is necessary even as a temporary measure. Here are some PVC joint repairs, hope below points may help you to avoid leakages.
