The Gleco Trap provides you with an economical plumbing trap that is both easily installed and maintained. It is connected below the sink and collects solids in a bottle, which has a fine line. When the solids reach the fill line, the trap is drained through a valve, the bottle is exchanged with a replacement, the valve shut and then the trap is back in service.
The second best part with this product (the first being it prevents your drain from clogging of course) is that changing the bottle is fast and done without any tools! Most of all, there is no mess and less chance of water spilling out.
