The plumbing rough-in for a toilet is the plumbing setup that occurs before the toilet is installed in the bathroom. This includes the basics of the toilet drain, which consists of a waste line, a supply line, and a vent pipe.
The waste line carries waste to the main drain or sewer pipe; the supply line brings water to the tank of the toilet; and the vent pipe allows air to move through the system as necessary. Each of these pipes should be connected according to local building codes and then run through the walls or floor, up to the necessary height where the toilet will be located.
The rough-in should also consider the height of the person who will be using the toilet, as well as any special needs that may require additional plumbing. The rough-in should also take into account any fixtures, such as a sink, shower, or bathtub, that are located nearby.
After the rough-in is complete, the actual installation of the toilet can proceed.
Is toilet rough in from finished wall?
No, toilet rough in is not from finished wall. Toilet rough-in typically refers to the distance from the wall at which the closet flange (the fitting which attaches the toilet to the waste pipe) is located.
This installation measurement is important because toilets and their associated plumbing must fit within tight spaces. The rough-in measurement is typically 12 inches from the finished wall, but may vary depending on the layout and design of the bathroom.
A standard toilet is typically elongated and requires a rough-in measurement of 14. 5 to 15 inches. In order to accommodate additional space and set up for a comfort height toilet, a rough-in of 17 inches is typically used.
What does 12 inch rough in mean when installing a toilet?
The 12-inch ‘rough in’ refers to the distance from the wall behind the toilet to the center of the closet bolts. Installing a toilet with a 12-inch rough in means that the center of the closet bolts, which secure the toilet to the floor, is 12 inches from the wall.
It’s important to note that if the rough-in size is not compatible with the toilet being installed, the toilet cannot be securely mounted and won’t function correctly. It is necessary to measure the rough-in size prior to purchasing a new toilet.
Many toilets are designed to fit either a 10-inch or 12-inch rough-in, while other sizes, such as 14-inch, are available as well. It’s important to measure precisely as 12-inch rough-in toilets are not compatible with 10-inch rough-in models.
To change the rough-in size, the plumbing must be modified to fit the toilet.
Can a toilet drain be 3 inch?
Yes, toilet drains can have a 3-inch diameter. This size is the most common and comes standard with most toilets. In most cases, a 3-inch toilet drain is adequate to allow waste to flow freely and can handle a normal flush volume.
However, the size of the drain may need to be increased if you have a higher water flow rate, such as in a high-pressure toilet. In certain cases, this size increase may necessitate upgrading the entire toilet drain, depending on the particular plumbing system being used in the home.
The local plumbing regulations may require the water pressure to be reduced in order to properly use a 3-inch drain on a toilet, and a professional should be consulted to ensure the size is correct for the job.
How far does toilet need to be away from wall?
The minimum recommended distance between the centerline of a toilet and the wall behind it is 15 inches, though some require more space. This measurement should include the possible depth of the flange, which is usually between 3/4 to 1 inch.
This measurement also applies to any other obstruction or fixture that might be near the toilet, such as a sink, bathtub, or other plumbing fixture. The 15-inch requirement allows enough room for a person to sit comfortably and use the toilet without feeling cramped and it allows enough space for cleaners to perform routine maintenance.
How far from finished wall is toilet flange?
The distance from the finished wall to the toilet flange depends on a few factors, the most important being the type of toilet being used. Wall mounted toilets typically require a minimum space of 12 inches from the wall, while floor mounted toilets are usually flush with the wall.
When installing a toilet flange, it is important to measure the distance to the finished wall and add enough space to comfortably fit the toilet and other plumbing components. Some plumbers may require an additional 12-24 inches from the wall to accommodate any additional plumbing components and to ensure there is enough space for the toilet to be properly installed.
When installing a toilet, be sure to measure the finished wall to the flange and leave sufficient space to account for any additional components.
Can you install a toilet in a basement without rough in?
Yes, you can install a toilet in a basement without a rough in. You can use an offset closet flange with a wax ring to anchor the toilet. Select an adjustable flange, or an adjustable offset closet flange, or a toilet flange extension kit to fit in the bottom of the toilet that will fit over the existing pipe in your basement.
To install, turn off the water valve to the toilet and remove the old toilet. Cut your plywood subfloor to fit around the existing pipe. Place the adjustable flange or extension over the existing pipe, depending on the type of flange you use.
Put a bead of caulk around the underside of the flange for a water-tight seal. Install the toilet and rubber wax ring below the horn of the toilet. Add additional bolts if needed around the toilet flange, if desired.
Turn the water valve back on, and you’re done.
Does toilet need to rest against wall?
When it comes to toilets, there are a variety of installation options, depending on the type of toilet and the space available in the bathroom. In general, many toilets do need to be mounted against a wall but there are exceptions.
Wall hung toilets, often found in modern bathrooms, are designed to be mounted directly onto the wall and this may provide a more efficient use of space where there is limited floor space. There are also corner toilets and rounded models which are designed to be installed in a corner and may not require a wall.
For regular toilets, the right way to install them is to place the complete toilet against a wall and make sure that it is firmly and securely connected to the floor.
What is the difference between a 10 inch and 12 inch rough in toilet?
The main difference between a 10 inch and 12 inch rough-in toilet is the distance from the wall behind the toilet to the center of the waste outlet. A 10 inch rough-in toilet has a distance of 10 inches, while a 12 inch rough-in toilet has a distance of 12 inches.
Both are common toilet sizes and are available in several styles.
The 10 inch rough-in toilet is the more common size, and it is suitable for most bathrooms. It is important to note that the 10 inch rough-in toilet cannot be replaced with a 12 inch rough-in toilet, as the drain lines and waste outlet in the bathroom will not line up with the new toilet.
The 12 inch rough-in toilet, on the other hand, is typically used in larger bathrooms, commercial buildings, and some remodeled bathrooms, and it can accommodate both a 10 inch and 12 inch rough-in toilet because the drain and waste outlet locations are different.
When choosing a toilet, it is important to ensure you are selecting the correct rough-in size. If the wrong size is chosen, it can be difficult to make adjustments and the toilet cannot be returned. Therefore, it is important to measure the rough-in before purchasing a toilet.
Where should toilets not be placed?
Toilets should not be placed in areas that are exposed to extreme heat or cold, as extreme temperatures can cause toilets to break or malfunction while in use. Toilets should also not be placed in areas that are prone to flooding, as this can cause water damage or flooding to the surrounding areas.
Additionally, toilets should not be placed directly in front of a window or entryway, as this may create a draft for the rest of the home or compromise the privacy of those using the toilet. Lastly, in order to ensure proper air ventilation during and after use, toilets should not be placed near any exhaust vents, deep heaters, or other sources of heat.
Do and don’ts in toilet?
When using the restroom, it’s important to practice proper hygiene and follow certain etiquette. Here are some do’s and don’ts for using the toilet:
Do’s:
1. Close the toilet lid before flushing. This helps keep germs from spreading.
2. Wash your hands after using the toilet before heading out.
3. Disinfect the surface of the toilet seat and flush handle with a disinfecting wipe or spray before using the restroom.
4. Let other people in the house or business know when you are done using the restroom so they can use it.
Don’ts:
1. Don’t leave used toilet paper or paper towels laying around the restroom.
2. Don’t flush anything other than toilet paper, as this can cause plumbing problems.
3. Don’t smoke or vape in the restroom.
4. Don’t put your phone on the toilet while using it.
How high should a toilet flange be?
The height of a toilet flange should be adjusted so that the top of the flange is level with the finished floor surface or slightly above it. The American National Standards Institute (ANSI) recommends that the toilet flange should be set at a height of 12 to 15 inches.
This will ensure the flange is above the flooring material and allows for a tight seal when the toilet is installed. Some newer styles of toilets may require a slightly different flange height and it is important to consult your toilet’s installation instructions before adjusting the height of the flange.
As a general rule, the higher the flange is, the better, as any movement due to changes in ambient temperature may create a leak if the seal is not tight enough.
Does toilet rest on flange or floor?
The answer to this question really depends on the type of toilet being installed. If a standard or otherwise non-floating toilet is being installed, then it will rest on the flange. The flange is the metal or plastic piece that sits on top of the waste drain, connecting it to the toilet.
A good seal should be made between the flange and the base of the toilet in order for the toilet to stay firmly in place when it’s in use.
If on the other hand, a floating toilet is being installed, then the toilet will rest on the floor. This type of toilet is designed with a base, which sits on the floor instead of the flange. This base is usually made of a rubber material and is flexible so that it can move and adjust when someone is using the toilet.
This type of toilet installation allows for some flexibility in the installation process, as the flange must be perfectly aligned in order to be used with a non-floating toilet.
Regardless of which type of toilet is being installed, it’s important to make sure that a proper seal is made between the flange and the base of the toilet, or the toilet and the floor. If this is not done correctly, the toilet will come loose and can actually be dangerous.
It’s also important to ensure that the toilet is properly secured to the mounting bolts, as this will help to keep the toilet from wobbling when in use.
Does a toilet flange go inside or outside the drain pipe?
A toilet flange should always be installed outside the drain pipe. The flange is the rigid piece, usually plastic or brass, which is attached to the floor underneath the toilet and connects the toilet to the drain line.
The flange holds the toilet in place and it is sealed to the toilet’s drain pipe to ensure a water-tight connection. The lip of the flange should rest on the floor, while the hub of the flange slips through the drain pipe and is attached to the outside of the pipe.
To ensure a secure seal, the hub should be completely outside the drainpipe before any hardware, such as the bolts or clips, is installed.
How long should a supply line be from the toilet?
The length of the supply line from the toilet will depend on the layout of the bathroom and the existing water supply lines that exist in the home. Generally speaking, the supply line should be long enough to reach the water supply valve, which is usually located near the back of the toilet bowl.
This supply line usually needs to be between 8-12 inches in length. Additionally, if the supply line will be exposed instead of hidden beneath the toilet, it is important to ensure that it is long enough to reach around the base of the toilet, allowing for a more aesthetically-pleasing look.
To determine the exact length of the supply line needed for your particular toilet, it is best to consult a plumbing expert with experience in bathroom renovations or a manufacturer’s installation manual.
