Fitting the replacement nut

Wave pumps differ in thread size, so check the model of your pump before ordering, and compare the new nut with the old one or a photo of it if you still have it. To fit it, unplug the pump, take it out of the water and hold the body steady while you start the nut by hand, turning it gently until it catches the thread cleanly. Tighten it until firm but stop there, as overtightening can strip plastic threads or crack the housing. Before switching on, check that the bracket, suction cups or magnet holder sit securely against the glass, then listen for rattling once the pump is running, which can mean the nut has worked loose. In marine tanks, limescale builds up on threads over time; soak them in a mild vinegar solution and rinse well during routine cleaning so parts come apart easily next time.
