Great no problem then. But I'm afraid I have no knowledge of your current filter, so can't advise. With my Eheims it's pretty simple and I just flick the lever to stop the water flow and then disconnect the pipes from the filter. Holding them above the tank and open the lever switch again will release the vacuum and the water freely runs out. Not sure if that makes sense and if your current filter has the same lever switches.
