The actual plumbers here will understand the use of a wet/dry vac to clear the remaining water from the tank of a toilet to do repairs such as replacing the fill valve. My 16 gallon unit is just two big and bulky to drag into some baths. I have one of the small 2 gallon "Stinger" vacs from HD. So weak on suction as to be virtually useless. Can't someone make a vac with good suction but manageable size even if frequent emptying is necessary? Do you have a good alternate method to clear the water remaining after flushing?
