take the pvc pipe coupler and attach it to the back end of the pump. (where the hose would have gone)



cut the 1inch pvc pipe to the length of the original nozzle. if you dont have this, you can just eyeball it so that it looks about right.



i cut mine to about 20cm. if you are lucky you will be able to just screw this into the front of the pump. if not heat one end of the tube and when warm and supple you will be able to screw it into the pump.



make a hexagon out of the acrylic plastic and sand down the edges to make it look like a bolt. glue this to a circle the same size as the pvc coupler.







If your pump has an attachment on the rear of the pump you will have to cut it off so the pvc coupler will fit.
