Before we start gluing things together we need to figure out how high this needs to be. Tap the pieces 1 through 7 together. It is best if you place teflon on the connectors to make sure you can dismantle them after. For me the height was very important because it would be fitting under the ledge of the tank. If yours is totally in the open, then it's not
too important. And also note not to cut the main
PVC pipe thinking this will be the end height when it is only temporarily placed together. When you actually pound the connectors together, it will make the whole standpipe shorter. But remember, you do not want to pound it too well before you are ready to make a permanent connection because you may never get it apart again.
We also need to prepare the end cap (otherwise known as #1 in the above photo).
This is where if you have a drill with a 3/16 drill bit the job is very fast and precise. It can definitely be done with a dremel, it just takes a little more care while at the risk of not having the same precision.
