Step 2: Preparation
PAY ATTENTION! This part is important
Cut your pieces according to the picture and the descriptions. These are just approximate measurements and you can customize them at will. Numbers indicate the PVC pieces and letters indicate the fittings. The measurements are all in cm. This is the list of pieces used. Make sure that before you cut them that you label them so you know which pieces go where.
1a: T shaped fitting
2a: Ball valve
4a: Elbow fitting
5a: Elbow fitting
6a: Elbow fitting
Mark lines on a long bit of PVC where your individual pieces will be. Then number each piece so that once you have cut them, you don't get them mixed up. To cut your pieces, use a serrated steak knife to make a large grove in the marked line you want to cut. Then once the grove is big enough, use a hacksaw to grind away. Beware, the hacksaw is not a precision tool. Don't be too messy or else your PVC pipe will be all rough. Once you have your pieces, it would be better if you sanded them to be nice and smooth.
Then arrange them in the order in the picture. You can lightly attach the pieces together but don't glue anything together yet.
Remember, use the picture!
