PVC 90 degree elbow pipe fitting can change the direction of flow by 90 deg. Two ends are connected the same size PVC pipe plumbing fittings.
Multiple elbows pvc pipe fitting can be used together in combination. For example, the following situation: pvc pipe fixed, pvc pipe and tee pipe fiting at the junction of damage, moving range is small.
There may be many ways to solve this problem of pipeline and pipe fitting damage，such us mechanical joint couplings is a solid way to join pvc pipe, but this is much more expensive, then the following describes pvc elbow fitting to repair the pipe.
Prepare materials: four 1inch pvc 90 degree elbow pipe fitting, one meter 1 inch pvc plumbing pipe, cut, pvc pipe glue
The above materials can be bought to the building hardware store, there are many brands to choose from, such as SAM-UK, etc.
Step 1: cut off the damaged parts of the pvc pipeline, including PVC pipe tee fittings.
In the pvc pipe damage at both ends of the appropriate location of the cut.
Step 2: Install two PVC elbows pipe fitting.
First of all, the original PVC pipe at both ends of the installation of a pvc elbow pipe fittings, there is a note to note that the two elbows parallel to the same direction.
Step 3: Connect the pvc 90 degree elbow pipe fitting to the new pvc pipe
First saw the ends of the same length of the pvc pipeline. The other two pvc elbow pipe fitting installation, to parallel counterparts. And then check the pvc pipe again to determine the required length. Finally, to determine the pvc pipe and pvc pipe fittings elbow connection, the use of PVC glue fixed molding.
If you want to install the nozzle or branch water in this position, you can use PVC reducing tee or equal tee pvc pipe fitting, as shown below.
Some people may think that this method will make water pressure loss. In fact, using four 90 degree pvc elbow pipe fitting, certainly more friction than the use of coupling, the pressure loss is also more, but in practical applications, the nozzle performance did not lose pressure.
But we also have to consider the issue of water pressure and flow rate, velocity needs to be less than 8 fps. pressure is <80 psi as per code, can be used.
This use of PVC 90 degree elbow pipe fitting method, there is a benefit, because the temperature difference, PVC pipe there is hot and cold shrinkage phenomenon，this will additionally allow for some expansion and contraction in the piping run.
