When you are installing a toilet, you’ll want to know how far it sticks out from the wall. Generally, toilets need 15 inches of clearance from the wall, plus the thickness of the wall, if you are adding tile. For example, a drywall wall with 3/8″ mosaic tile would need one inch of thickness. This would leave a toilet flange with a 16-inch front clearance, and the back clearance would depend on your local plumbing codes.

Installing a toilet with a rough-in

When installing a toilet with a rough-in, you must first measure the area to be flanged. The measurement should start at the bare wall above the baseboard and extend to the center of the toilet flange. Make sure the measurement is within standard limits, otherwise you may make an expensive mistake.

The rough-in should be easy to locate; the pipes will usually stick out from the wall by about 12″ to 14″. The pipes for water should be against the wall, about nine inches above the floor. The water supply pipe should be behind the drain and to the left. Most of the time, the rough-in piping is installed before the house is finished.

Before beginning, be sure to read the installation manual carefully. You will also need to know the local building codes for the area where you are working. It is important to note that you must remove the old fixtures and repair the water supply and the toilet flange before starting the installation. It is also essential to shut off the water supply lines and mark the length of the rough-in.

Identifying a toilet’s bolts

To properly tighten toilet tank bolts, you must first know where they are located. These bolts are usually located between the tank and the seat. Locate these bolts by using a non-permanent tool and turn them to the left until they are loose. Once you have identified the location of the bolts, you can proceed with tightening them. Make sure the bolts are snug, but not too tight to risk cracking the porcelain. If you notice any damaged bolts, you may need to use an extra tool to remove them. Otherwise, you can use a mini hack saw to cut them off.

Another way to tell whether toilet bolts are loose is by watching for leaks. If you notice a leak around the base of the tank, it’s likely a leak caused by the bolts. To determine if you need to tighten the bolts further, you should make sure that the washers are intact and are not deformed by the tightening. If you find that the rubber washers are squashing under the pressure of the bolts, then you have overtightened them.

Identifying a toilet’s flange

The first step in installing a new toilet is to identify the flange. The flange sits at an angle of 90 degrees to the wall, providing stability and a connection for the toilet. The flange also anchors the toilet to the floor, using three retaining screws. A straightedge can be placed on the top of the flange to help you gauge the angle.

The flange’s outside diameter is four and a half inches. The inside diameter of the flange should match the outside diameter of the pipe. If the two measurements are different, it’s important to get a measuring tape or other measuring tools to ensure that the flange is properly installed.

If the flange is placed on a corner, you may be confused about which wall the flange is on. If the flange is on the back wall, look for a small knob sticking out of the wall. This is likely the supply line.

Identifying a toilet’s water supply line

If your toilet is leaking, you should first try to identify the source of the leak. If you can’t determine its source, you may be able to diagnose the issue by checking the water line connection. This connection connects the toilet’s water tank to the wall. You will likely see either a plastic compression nut or a threaded connection. Compression nuts are easy to identify, as they are ring-shaped with a curved edge. If the nut is a threaded connection, however, you will need to remove the supply line first.

When you remove the old supply line, you may have to remove the water valve. It is possible that the valve is soldered onto the pipe, in which case you will need to use a tube cutter to cut the pipe close to the valve. Once you remove the valve, you may notice a little bit of water dripping from the old supply line.

A leak can be hard to detect, so it is important to know exactly where it is coming from. If you can pinpoint the source of the leak, you will prevent unnecessary damage to the bathroom and unnecessary charges to your water bill. Supplies lines don’t last forever, so it’s important to replace the leaky fittings and hardware to avoid further damage.
