Mop sinks are usually found inside a janitor’s closet, but due to the convenience they offer, household owners are also putting one in their houses. Mop sinks can be installed in the laundry, mud room or garage. Since they are usually installed at floor level, mop sinks eliminate the need to lift heavy buckets of water.  They also offer convenience when cleaning unusual sized items.

Step 1 - Location

Before installing one in your house, bear in mind that mop sinks take up some space so it is important to decide where you want to install it. The location of your waterline is also important. Measure the area where you want to put the sink before buying one. Mop sinks usually come in different shapes depending on need and space constraints so that leaves you with some flexibility in your choice.

Step 2 - Handling

Before installing, carefully inspect the product. Check for damages by wiping the face with a wet cloth. When it dries out, any cracks will be noticeable. Remove mop sink from carton at installation point. Don’t place it on its edge or the corners will chip and become damaged.

Step 3 – A Large Enough Sub-hole

Make sure the hole in the sub-floor is large enough to accommodate the drain and that it coincides with the hole in the mop sink. The hole should be 6 inches in diameter; the drain pipe at least 5/8 inches below sub-floor surface. Set the drain body into place by making sure that screws or drain align with notches on drain opening. Place mop sink into place and level as required. Seal drain with lead and oakum.  eal all edges where wall contact is made.

Step 4 - Leveling

Level mop sink carefully by putting at least 1/4 foot clearance between the wall and the mop sink. Put a layer of mortar or sand on the desired area where you want the mop sink installed as support in case the sub-floor is uneven. Expose the grout along the edges.

Step 4 – Remove Drain Pipe

Remove the drain pipe first before putting in the mop sink. Avoid dropping it on the pipe. Instead, put the mop sink in before inserting the pipe through the drain. Secure and tighten with a wrench.

Step 5 – Lubricate Gasket

Use soap to lubricate gasket. Stretch the mop sink over 3 inch pipe with letters facing up. Push gasket as far as possible into the joint.

Step 6 – Hammer it in

Work around the gasket with a series of blows from a hammer or a piece of wood to drive the gasket into drain body until it bottoms. Check and see if the drain pipe is even with the gasket top.

Step 7 – Test the Connection

Before covering or concealing, test the connection first. Plug in 3 inch drain and fill receptor with water. Make sure to check for leaks. This must be done before finishing walls.
