If you are planning to replace your sprinkler manifold and have never done it before, you may find it helpful to read up on a few mistakes people commonly make.

1. Forgetting About Backflow Prevention

One common mistake many people make when they are replacing their sprinkler manifold is failing to make sure they have backflow prevention.

This means the water from the system, often not as clean as you would like for drinking, can't get into the house's drinking supply.

This is often installed initially, however, if you are replacing it, you may take it out and not know to put it back in, resulting in irrigation water ending up in your drinking water.

2. Miscalculating Distance From Timer

Many times people don't think to place the manifold close enough to the timer and end up running long wires under the ground or around the yard.

While it certainly works to run wires, it can also prove to be dangerous and unappealing to the eye.

By placing the manifold near the timer you will be able to use a shorter wire and lower your risk of having electrical problems.

3. Not Having Enough Room

Many times when you are replacing the sprinkler manifold you will realize you have run out of room and didn't prepare enough for the size.

Because of this space problem, you are unable to line up the manifold and parts the proper way. An easy fix for this--instead of fumbling around and potentially damaging the system--is to just add more pipe.

By adding more pipe to the sides you can re-route the system back further and then you will have more room to line everything up efficiently.

The best way to avoid this mistake is to take your time in the beginning of the project and dig the right size hole. Digging a bigger hole is always your best bet as you can easily fill it in.

It is often much harder to increase the hole size when you are in the middle of this project than it is to go smaller, so always leave yourself enough room to work.

4. Using Crimp-On Fittings

While using the crimp-on fittings will prove great in holding them together, it will also be a tough task to replace later on.

If you are someone who does a lot of yard work, or are installing this system in a spot where it could potentially be hit by a lawn mower, then you want to make sure you have replacement parts and they are easy for you to change.

Before beginning this project it may be best to look for fittings you are comfortable with and you know how to remove in an easy manner.

Keeping maintenance in mind while you are installing or replacing any part of a sprinkler system is a must.
