Cut the 2" PVC to the size you want for your chamber. We cut ours to 18", but this has been more powerful than we needed. 12" would have been better.

Use the PVC primer and cement to weld together these pieces:
2" cap
2" PVC pipe
2" coupler
2" to 1" bushing

That is the main chamber. Then you will be adding these two pieces in order to be able to connect to the modified sprinkler valve:
4" piece of 1" PVC pipe
1" threaded male adapter
