The showers have very small water traps. There is a spray you can use to squirt down after a shower and also the overflows on sinks. It is made for this purpose and comes with a plastic straw (like WD 40)
Another way (which I did) was to but the drip feeders that fit onto old soft drinks bottles, then set the drip on the plug and let it drip every few mins to keep the trap water level.
