How to Attach a Hose Bib to a PVC Pipe
PVC pipe has become a useful and versatile plumbing source which makes for very simple do-it-yourself projects such as connecting a hose bib. Through cutting and fitting the PVC with joints and elbows, the hose bib can be routed almost anywhere affordably and easily.
Step 1 - Select Hose Bib Diameter
Larger spigots have a higher flow rate, so assess the needs of the individual project to determine the correct diameter. Turn knobs can either be 3/4 turn and have a large degree of adjustment or hand cranks to allow for micro adjustment.
Step 2 - Select Coupling
The coupling is the adaption piece which fits over the PVC pipe and over the hose bib allowing the two to be attached together. It is important that one end fits the PVC pipe diameter and the other fits the hose bib. The end which will fit the PVC is not threaded; however, the hose bib side will need to have adequate threading.
Step 3 - Turn Off the Water Source
Whenever working with water, be sure to turn off the water source. Allow the pipes to drain and dry so the PVC pipe cement will set.
Step 4 - Route PVC to Desired Location
Use elbows, joints and small PVC sectional piping to route any piping from the water source to the desired location of the spigot. A hacksaw is the best to cut PVC pipe to individual needs. Using the PVC pipe cement coat both the inside and outside of the pieces being jointed to insure adequate seal. PVC pipe cannot be removed once it is cemented without permanently cutting the pipe.
Step 5 - Test Fit the Coupling
Due to couplings being mass produced, the individual connection with the PVC pipe may not be an ideal fit. Test fit the coupling onto the PVC pipe to be sure the connection is smooth. Firm pressure will be needed to push the coupling through on the PVC end; however, wrenching should not be required. If the coupling will not fit on ideally, use the utility knife to slightly bevel the edges of the coupling. Test fit again. If still not smooth, sand the outside of the PVC pipe slightly until the coupling will fit.
Step 6 - Gluing the Coupling
Clean both the inside of the PVC coupling and the outside of the PVC pipe with a water and a paper towel to remove any residue. When clean and dry, use PVC cement to coat both areas and attach the PVC pipe into the coupling. Be careful with the glue as once the pipes are cement, only hacksawing will remove them.
Step 7 - Fitting the Hose Bib
Clean and dry the interior threads of the hose bib. Wrap the threads four times with Teflon tape. The hose bib should fit so snuggly it must be forced onto the PVC coupling as this is the only way the Teflon tape can adequately seal. Plumbing tape, thread tape and Teflon tape are all basically synonymous for this project.
