Some time ago I tarted a thread and all of the pictures came up missing.
So I am starting it here again hopefully with the same pictures and and some new ones.
The first one here is a homemade water hammer arrester.

If you have a lot of flow and pressure going to you garden the simple use of pipe and fittings will stop the hammer.
This hammer effect can cause problems such as fittings coming apart.
Since air compresses the pressure is absorbed by the air pocket in the chamber.
