Looking for a quick PVC repair? Need to quickly cap the end of a pipe? Tired of getting blue glue all over your hands?
You might consider using push-fit fittings for a quick repair on PVC pipe. Push-fit fittings are an easy alternative to traditional solvent-glued fittings for use in PVC installations and repairs. While they can also be used for other types of plumbing pipe, including copper and CPVC, they are especially useful for PVC irrigation pipes and are now readily available in many hardware and home improvement stores.
There are various advantages to using PVC push-fit fittings. For starters, there is absolutely no solvent glue required for installation, so you have one less thing to purchase. Also, no glue means there is no drying time, which will save you time on the job. Unlike traditional glued PVC fittings, you can install push-fit fittings when the pipes are wet, so long as the pipes are clean, which can be a huge advantage in situations where the water does not shut off completely.
Frequently Asked Questions
Now let us take a look at some common questions and concerns regarding PVC push-fit fittings.
Q. How do they stay in place?
A. Push-fit fittings have metal barbs that allow one-way pipe access. The end of the pipe is pushed in, and then the barbs grip the surface of the pipe and hold on so that it cannot be pulled back out.
Q. Are they really watertight?
A. Yes. Push-fit fittings include a rubber O-ring that fits tightly around the pipe. The compression fit of the rubber ring on the pipe creates a watertight seal.
Q. How are they removed?
A. The push-fit mechanism is not removable, so, like glued PVC fittings, to remove these fittings you must cut the pipe on either side of the fitting. Please note that this type of fitting cannot be dry-fit for measurement purposes, as you can with glued PVC fittings, so don’t push them onto the pipe until you are ready to make the joint.
Q. Can they be used with water in the pipe?
A. Since there isn’t any glue that can be affected by water, PVC push-fit fittings can be installed in wet conditions. While it is still necessary to shut off the water, you don’t have to worry about a small amount of water in the pipe. The main things to look out for are clean conditions and full engagement. So as long as the pipe is clean, these fittings can be installed. Just make sure to push the pipe all the way into the fitting to ensure that it is fully engaged and that the joint seals properly.
Q. How much PSI pressure will PVC push-fit fittings withstand?
A. The PSI and water temperature thresholds vary for PVC fittings. Check for manufacturer specifications and usage when you purchase fittings. If a fitting is labeled for irrigation use only, it is likely to meet the same usage specifications as other PVC irrigation fittings, but it never hurts to double check.
Q. What sizes do these fittings come in?
A. PVC push-fit fittings are available in many of the same standard sizes and configurations as other PVC irrigation fittings. The availability can be limited in some stores based on popularity, but the most commonly used fitting types and sizes are usually readily available.
