TIP: Clean The Garage
TIP: CLEAN THE GARAGE and check the drainage. Sweep it. Spray it. Inspect it. Clean the drain if necessary. Replace covers as needed.
If you smell foul odors coming from your floor drain, it’s because the traps have dried out. Floor drains have U-shaped P-trap pipes just like your bathroom sink drain. The pipe is designed to hold water, which stands in the pipe and prevents sewer gases from coming up through the drain.
If you smell sewer gas, grab a bucket of water and start pouring it into the floor drain. Go ahead a dump a gallon or two or preferably a whole five gallon bucket of water into the drain. This will not only seal off sewer gases, it will also let you see if the drain is working properly. If it’s clogged it won’t be able to do its job when called upon.
