How To Repair A Broken Pvc Sprinkler Pipe

Bert spent 25 years working as a home-improvement and residential construction contractor in central Florida.

Just as there is with many issues in life, there is more one mode to set a broken sprinkler pipe. The appropriate method depends on the damaged section's location. For instance, a clean break earlier the valve usually requires a hard pipe repair, while easier repair methods piece of work fine when the damaged area occurs later the valve.

This guide will suspension down five unlike methods to repair a buried sprinkler pipe.

Geysers often erupt when a sprinkler pipe breaks earlier the zone valve.

Locate and Betrayal the Damaged Pipe

Finding the leak is sometimes the about hard role of this project. Obviously some leaks are easier to notice than others, such every bit a geyser that rips through the soil. In less obvious cases, a homeowner may only notice a pressure loss at the finish of a zone. In this situation, plow on the leaking zone. Stand up back and compare the spray meridian of each sprinkler head. If you see a loss in water pressure between 2 sprinkler heads, suspect a leak betwixt these two heads. Go to the suspected expanse and look for overly saturated soil.

Remove the soil covering the broken sprinkler pipe with a shovel. When the tool'southward bract touches something hard, stop digging with the shovel and expose almost a ii-human foot-long section of the piping with either your paw or small trowel. Clear a four- to vi-inch deep trench under the sprinkler line. This gives the water inside the pipe a place to drain.

Identify the pipe size earlier shopping for repair fittings. The person at the hardware store does not know what size pipe you have. Manufacturers impress the pipe size on the side of the pipe. Unfortunately this is often hard to read when on older buried pipage. If this is the case, wrap a piece of cord effectually the pipe and make a mark where the end meets. Go the hardware shop and use the cord to identify the pipe size. If you lot feel the need to gamble on pipe size, cull 3/iv inch.

Saddle Repair Kit

Irrigation repair technicians utilise a saddle repair kit to set a cracked department of directly pipe, such as when someone punctures a sprinkler pipe with a shovel. The pieces in these kits hug pipe, non fittings; leaking fittings require a hard pipe repair. Some kits utilize a PVC saddle and cement, while others utilize a prophylactic gasket and metal clamps.

PVC Saddle style

1. Wipe the damaged area with a rag to remove mud and dry it. If h2o continues to seep from the break, plow off the water source and remove the closest sprinkler caput. This releases the water pressure from the pipe.
2. Paint the pipe with a PVC cleaner or primer. Using a PVC cleaner or primer helps ensure the repair kit bonds permanently onto the pipe.
3. Apply a liberal amount of cement to both the pipe and the repair kit.
4. Position the kit's pieces over the damaged surface area and snap them together. Let the cement dry, using the time recommended by kit manufacturer as a guide, earlier leak testing.

Clench Fashion

1. Make clean the surface of the damaged pipage with a rag. Remove all dirt and debris.
2. Slip the clamp over the damaged area of the pipage. Position the clench's rubber gasket over the damaged surface area.
3. Get together the clamp. Tighten the clench'due south bolts with the correct sized wrench. Turn on the water source to check for leaks.

A pre-assembled flexible coupling

Flexible Coupling

Many homeowners dear the copse in their thousand. Unfortunately, as the roots grow, they button up on any irrigation pipes running above them. Eventually the tension causes the pipe to crack and leak. The root'due south upward force creates uneven pipes that sit down at odd angles to each other, making a hard pipage repair difficult. To make matters worse, removing the offending root can damage or kill the tree. A flexible coupling solves this issue without cutting the roots.

1. Lay the flexible coupling on the damaged pipe and center information technology over the split in the pipe. Apply the coupling to determine where to cutting the pipage and marker the pipe with a pencil at the appropriate spots.
2. Cut pipage on the pencil marks with PVC cutters. Remove any burrs with a knife.
3. Let the water drain from the pipe. Dry and clean both ends of pipage with a rag.
4. Utilise a liberal corporeality of wet-or-dry PVC cement to the both ends of the flexible coupling and the sprinkler pipe. Quickly move to the next footstep.
5. Slip both ends of the coupling over their respective pipe ends. Twist the coupling back and forth about 1/4 to one/2 plow. Let the cement dry, using the manufacturer's instructions as a guide, then leak test the repair.

Some technicians apply a PVC compression plumbing fixtures every bit a no-cement repair plumbing fixtures.

Pinch Coupling

Irrigation repair technicians looking for a no-mucilage fitting often choose to use a PVC pinch coupling, sometimes chosen a dresser coupling. A PVC compression fitting uses prophylactic gaskets every bit a mechanical sealant. When the technician tightens the fitting'due south basics those nuts force the rubber rings into the void between the pipe's outer surface and the fitting. If the fitting leaks, the technician simply tightens the nut another half turn. Unfortunately, a PVC dresser plumbing equipment should not be used on a abiding pressure piping, such as the piping feeding the valve. In that case, choice a different repair method.

1. Remove nearly two inches of pipe. This cutting does non demand to be verbal, but shut.
2. Slide both dresser basics over their respective ends of the piping.
3. Work both rubber bushings onto their respective pipe ends. Button i rubber bushing about five inches abroad from the cut end of the piping. Position the 2nd rubber bushing about one inch from the end of its pipe.
4. Slip one cease of the dresser coupling over the piping with the bushing placed five inches from the cease. Go on to adjust the fitting until the free end clears the remaining pipage.
5. Position the stop of the compression fitting against the rubber bushing that sits one inch away from the pipe. This should center the coupling over the two-inch gap.
6. Slide the afar bushing toward the coupling until it touches the fitting. Both rubber bushings should now touch on the fitting. Tighten both nuts with a wrench.
7. Turn the water pressure level on and leak test. If the plumbing equipment leaks, identify one wrench on the coupling and a second on the leaking nut. Agree the coupling still and turn the nut approximately one one-half plow. Repeat equally necessary.

An expandable coupling works well in tight spaces.

Expanding Coupling

An expanding coupling, sometimes chosen a scope coupling, works well when replacing a leaking fitting located in a tight infinite, such equally inside a valve box. The stationary end of this plumbing fixtures attaches directly to a department of pipe and the plumbing fixtures'south movable shaft slides into another pipe fitting. Occasionally a repair technician completes a hard-pipe repair with an expandable coupling; nonetheless, this state of affairs rarely happens due to the fitting's high price.

1. Fully expand the coupling and measure its length. Subtract ii inches from the measurement and transfer the adding to the leaking sprinkler pipe.
2. Cut the sprinkler line at the advisable spot with PVC cutters. Let the h2o draining from the pipe absorb into the ground earlier continuing.
3. Wipe the PVC piping in the repair area with a dry rag. Removing all the dirt and debris from the piping helps ensure a leak-costless connection.
4. Attach a PVC fitting to the stop of the piping that accepts the expanding coupling'south shaft. The type of fitting depends on the repair. If the shaft connects to a threaded valve port, glaze a male fitting's threads with thread record before installing it on the valve. If the shaft slides into a coupling or other fitting, employ PVC cement to both the piping and plumbing fixtures. Install the fitting on the pipe, using a twisting move.
5. Fully compress the expanding coupling.
6. Apply cement to both the PVC piping and the expandable plumbing fixtures'south coupling end.
7. Mountain the expanding coupling onto the pipe, using a twisting movement. The twisting motion blends the cement.
8. Embrace the shaft'southward mating end and its fitting with PVC cement. Apace slide the shaft into the plumbing equipment. Rotate the shaft back and along slightly. Follow the cement manufacturer'south recommended curing fourth dimension before leak testing.

Hard Pipe Span

Occasionally it makes sense to build a hard pipe bridge using PVC pipe and fittings, such every bit when a sprinkler line passes over multiple growing tree roots or when the leak is located in an expanse too small for other methods. The exact type and corporeality of fittings needed depends on the state of affairs, however, most pipage bridges apply four 90-caste fittings and a section of pipe.

1. Dig a ditch across the entire repair area. This exposes all obstacles.
2. Cut the pipe on both ends of the repair with PVC cutters. Let the water drain from the pipe and soak into the soil. Dry out and clean the pipe ends with a dry rag.
3. Attach a xc-degree fitting to one buried sprinkler pipe with PVC cement. Turn the fitting until its open port faces up. Repeat this on the other cached pipe. Both 90-degree fittings must confront the same direction.
4. Cut two risers from a length of PVC pipe. The length of the risers depends on the amount of summit needed to clear the obstruction. It sometimes helps to lay a scrap piece of piping on the obstruction in the trench and measure the distance from the lesser of the bit to the peak of the buried piping. Try to keep the risers every bit minor as possible. Cement a xc-degree plumbing fixtures onto each riser.
5. Measure the length of the removed department of pipe. Transfer this measurement to a new piece of pipage and cutting at the advisable spot.
6. Attach one of the 90-degree fitting on i riser to the new piping with PVC cement. Cement the xc-degree fitting on the remaining riser to the pipe'southward other cease. Twist the ninety-degree fitting until the second riser'southward position matches the first.
7. Apply a liberal amount of PVC cement to both of the 90-caste fittings connected to the buried sprinkler piping. Position the bridge in the trench and slip a riser into each buried fitting. Press the risers into their respective fittings. Allow the cement cure completely before leak testing.
