While preparing food, grease accumulates on dishes, pans and utensils. When cleaning these items, the grease runs off into the drains. When it combines with other debris, it can clump together and solidify. This will clog the plumbing. Clumps may have to be removed chemically or with other devices. In extreme cases, you may need professional help to clear the pipes. A grease trap is one way of ensuring this will not become a problem.
- Skill level:
Things you need
- Large plastic barrel
- Tape measure
- Hard plastic sheet
- Silicone caulking
Consider where you want to place the grease trap. Remember that you need easy access so it can be cleaned. Usually, the cabinet under the sink is the best place for the grease trap.
Take a large plastic barrel, at least 35 inches tall. Saw the top of the barrel. Keep the top to use as the lid.
Measure the diameter of the outflow pipe to the sink. With a marker, draw circles about halfway up both sides of the barrel. The circles should be the same size as the outflow pipe.
Using a sharp knife, cut out the circles. Cut just outside the circles to ensure the pipe will fit.
Measure the width and height inside the barrel. Cut the hard plastic sheet to fit the width, but six inches short of the height.
Place the plastic in the middle of the barrel, between the two holes you cut, even with the top of the barrel. Seal the vertical edges with silicone caulking.
Put the barrel in place. Redirect the outflow pipe from the sink into one side of the barrel. Cut the pipe to the size to fit into one side of the barrel. Cut the rest of the outflow pipe to fit into the other side of the barrel and connect it so it continues through the outflow pipe. Use the silicone caulking to seal the pipes where they enter and exit the barrel. The waste will flow into one side of the barrel. As the water sits on the entering side of the barrel, the grease will float to the top and the water will flow under the wall into the other side.
Tips and warnings
- After installing the grease trap, it is important to clean it regularly. Depending on the amount of grease you put through it, you may have to clean it biweekly or monthly. You do not want to neglect it and let it build up. That will cause other problems with draining the sink.
