Pipe Repair And The Tricks Associated With It
Last week, we wrote a great article about pipe repair here. What we described was the professional way to fix a pipe leak that is underground. But what if you your budget is tight and you need to do it yourself with a temporary fix? There are many tricks you can do to fix a sprinkler pipe, but be warned, a temporary fix for underground sprinklers is NOT RECOMMENDED. You really should have a professional fix this or do it the correct way before you put the dirt back in. Common sense, right?
Anyways, there are 3 types of pipes. PVC (plastic), galvanized (hard metal) and copper pipes (soft metal). Almost all of the underground sprinklers systems for residential and business use PVC. Why? Because it’s cheaper. Most farms use galvanized steel pipes. Copper is more expensive but doesn’t corrode or rust like galvanized piping. It’s also lead free which makes it way safer. Copper is also soft and easier to shape and join by soldering or brazing but can be terrible for winter freeze like in Central Oregon.
Our last article explains how to dig up the pipe and fix with metal, but you really can add metal to pvc and pvc to metal and many people do not realize this. We don’t recommend it, but there is a way to add plastic to metal and vice versa using the exact same techniques as described in our last article. Whether it’s glue, adaptors or pressing, there are several ways to get a tightly sealed joint to achieve pipe repair. Unfortunately, you cannot glue pvc pipe directly to metal. PVC cement creates a solvent bond with plastic only. But adhesives, fasteners and pressure sensitive tapes are the way to go.
Fasteners
Fasteners clinch into the metal which hold two panels together. Generally, this is with a threading type bond. You can screw the pvc into the metal pipe however, you will need to thread both the metal and the pipe which requires certain tools. You can also use oekem (rope type material) and pour lead to make the connection as well. And finally, rubber bushings. Fit the rubber on the outside and at least six inches while using metal clamps fasteners to tighten the fittings.
Adhesives
Tube based epoxies like J-B Weld need curing and requires time and fasteners. Clear like silicone, this odoriferous stuff can be deadly so use ventilation with a mask. Epoxy putty looks like clay and feature two sticks which when applied together form the adhesive which is called kneading. Pressure sensitive tapes could be its own category but it really acts as an adhesive. These tapes have threaded like material that help gum the different surfaces together. Sometimes water or heat are used to fuse the tape into the surfaces.
