What is the standard size of a tub drain?

The standard size of a tub drain is typically 1 1/2 inches in diameter. If you are installing a new tub, it’s important to make sure that the drain size corresponds to your existing plumbing system. Not doing so could lead to improper drainage, potential flooding, and other costly issues.

Generally, most existing residential bathroom tubs have a 1 1/2 inch tub drain, though there are some older homes with drains that are 1 1/4 inch in diameter.

Are bathtub drains a standard size?

Generally speaking, most bathtub drains are a standard size. The drain is typically 1 1/2 inches in diameter, and the plumbing will be the same size except where a strainer is used. The standard drain size is typically referred to as a 2-inch drain, which includes both the strainer and the drain body.

This size is standard in the United States, though other countries may use a different standard size. When purchasing a drain for a new bathtub or shower installation, you should make sure it is compatible with the existing plumbing.

Most drains are made of plastic, but they can also be found in brass, chrome, and other materials.

What size pipe should a tub drain be?

The size of the pipe used to drain a tub will depend on the size of the tub itself. Generally, a 1-1/2″ diameter pipe should be used for most bathtub drains. If the drain opening for the tub is located further away from the tub (such as in the floor or wall), then a 2″ diameter pipe may be necessary.

It is also important to make sure that the pitch of the drainpipe is sufficient to allow it to drain properly; the pitch should be at least 1/4″ per foot. Additionally, it is advisable to use a P-trap as close to the tub drain opening as possible to prevent sewer gasses from getting into the room, and for added safety.

Can you use 1 1 2 pipe for tub drain?

No, 1 1/2 inch pipe would not be suitable for drain pipe for a tub. It is recommended to use 2 inch pipe for tub drains. This is because a 2 inch pipe has a larger diameter, allowing for greater air flow when draining.

Additionally, a 2 inch pipe is more able to handle the large volumes of water which a bathtub can produce. The larger size also allows for the possibility of adding a clean-out trap adapter in the future if need be.

Overall, 1 1/2 inch pipe is simply not big enough to handle the job that a larger diameter pipe such as a 2 inch pipe can provide.

What are the rough in measurements for a bathtub drain?

The rough in measurements for a bathtub drain will vary depending on the type of drain and bathtub that you are installing. Generally, the drain will be centered in the tub and typically between 5” and 6” inches away from the outside edge of the tub.

It is important to ensure that the rough in measurements of the drain fit the existing drain flange in your wall or floor. It is beneficial to measure the existing drain flange to ensure the proper size for your new tub installation.

Additionally, if you are installing a new floor drain you will typically need to measure from the face of the finished wall to the center of the proposed drain location. It is also important to be sure that the drain opening that you choose is the correct size for the tub and the drain assembly.

How do I know what size bathtub drain to buy?

When purchasing a bathtub drain, it is important to make sure that you are getting the proper size for your tub. To do this, you will need to measure the dimensions of the existing drain in order to find the correct size.

Start by measuring the diameter of the drain up to the opening. This measurement will provide the diameter you need to match when buying a new drain. Next, measure the drain’s total height, including any sections that stick out of the floor, such as a long tub overflowing tube or a lift and turn mechanism.

Once you have these measurements, you can compare them to bathtub drains that are designed to fit standard tubs with round or oval openings. You may also need to measure the height of your tub’s floor if you’re working with a tub that does not have a standard size.

Finally, you’ll need to find a drain size that matches both the diameter and height of your tub. It is recommended that you purchase a drain of the same size as your current drain, but you may need to buy a drain of a slightly larger diameter in order to fit the height of your tub.

Are all tub drains the same?

No, not all tub drains are the same. The most common type of tub drain is a “pop-up” style, which is characterized by a lever or knob which can be used to open or close the drain. These types of drains are relatively easy to install and are very common in bathrooms.

Other popular types of tub drains include “toe-taps” or “trip-lever” drains which feature a handle or lever located behind the faucet. These are often used in larger bathrooms and require a bit more installation time and effort.

Other types of tub drains may allow for direct connection of the drain to the P-traps eliminating the need for an overflow pipe. Specialized drains such as hair-catchers or shower assembly drains may also be installed depending on the type of tub and its usage.

How far off wall is tub drain?

The ideal distance from the wall to the tub drain depends on the type of bathtub you have and the layout of your bathtub. For example, if you have a freestanding tub, you will want the drain to be 7-9 inches away from the wall.

If you have a built-in tub, the drain should be about 6-7 inches away from the wall to allow for adequate water drainage. Additionally, if you have a drop-in tub, the drain should be no more than 6 inches from the wall.

It is important to have the proper distance to ensure that the bathroom floor will not flood or cause any other major issues.

Can you put a 90 in a drain line?

No, you cannot put a 90 degree elbow in a drain line. Instead, a 45 degree angle fitting should be used in the majority of drain lines. This is because the angle of a 90 degree elbow restricts the flow of water down the drain line which can cause clogs and backups.

Additionally, the 90 degree angle can increase the chances of a blockage forming by allowing debris to settle in the corners of the curve. An additional issue is that the sharp turn of a 90 degree elbow increases the risk of damage to the drain line from add-ons and bends during installation.

For these reasons, a 45 degree angle should be used instead.

How far can a drain pipe run horizontally?

The maximum length of a horizontal drain pipe run depends on the pipe diameter, pipe material, and the drainage system, as well as elevation and number of fittings. Generally, the maximum length for a pipe run should not exceed 50 feet for 1.

5”, 23 feet for 3” and 33 feet for 4” drain pipes. Pipes made from ABS can run slightly longer distances than those from PVC due to their smoother inside surface. However the maximum absolute lengths should not be exceeded due to the increased risk of clogging and other problems.

When deciding on the length of the pipe run for a drainage system, it is important to factor in other aspects such as the size of the water fixtures and the drainage capacity needed and make sure that the combined total length of all the drain pipes in the system is within the permitted length limits.

Additionally, the distance of the horizontal run should also be taken into consideration when calculating the necessary slope needed for the water to flow effectively. In cases where the total length of the drainage pipe run exceeds the allowed maximum limit, the line should be divided into multiple smaller lengths with a vertical offset at midpoint between them.

This will help to ensure proper drainage.

How do I measure my bathtub drain?

Measuring your bathtub drain is an important part of replacing or upgrading an existing drain. To get the correct size and measurements for the new drain, it’s important to measure the current drain correctly.

Begin by looking at the sides of your drain. You should be able to see a visible outline of the drain. Measure the width of the drain. You will want to measure from the furthest point of each side. Place the measuring tape at each point, and then measure straight across the widest part.

Next, you will want to measure the length of the drain. Do this by measuring from the furthest point of the left side to the furthest point on the right side. Again, use a measuring tape and place it at each farthest point.

Finally, measure the depth of the drain. Start by removing the drain stopper and inserting the tape measure into the drain pipe. Measure from the drain’s highest point to its lowest point, before the pipe curves away.

With your measurements complete, you can go ahead and purchase the correct bathtub drain for the size of your tub. Make sure to double-check the measurements before purchasing and installing the drain.

What size tub drain do I have?

The size of tub drain you have depends on the bathtub itself. Different bathtub sizes require different drain sizes, so you should measure your bathtub to determine the size of drain you need. To do so, you should measure the drain hole first (the hole in the center of the bottom of your bathtub), and then measure the distance between the two drain holes.

This measurement will help you determine which size of drain will fit your tub. Most standard bathtubs have a 2-inch tub drain, but this could vary for other models. Once the exact measurement is obtained it is important to match your drain size to the specific bathtub model so that the installation process can be done correctly.

Is drain pipe measured inside or outside?

When it comes to measuring drain pipes, it really depends on the type of pipe you are dealing with. If you are dealing with an ABS pipe, the measurements are taken from outside diameter (OD), meaning the width of the line from one side to the other.

However, if you are dealing with a PVC pipe, the measurements are taken from inside diameter (ID), meaning the width of the inside of the pipe.

So when you are measuring out a drain pipe, make sure you check what type of pipe you have, and measure accordingly. If you are not sure, you can use a ruler to measure the pipe, and then use online calculators to calculate the OD or ID depending on the type.

Can you replace an old tub drain?

Yes, you can replace an old bathtub drain. It is a relatively straightforward project that should take no more than two or three hours, depending on the type of drain and the condition of the existing drain assembly.

You’ll need a few tools, such as a basin wrench, adjustable wrench, and a drill. First you’ll need to remove the old drain by turning off the hot and cold water supplies and disconnecting the drain. Once disconnected, you’ll need to use the basin wrench to unbolt the drain from the tub.

After the old drain is removed, thoroughly clean the area around the drain opening to make sure it is free of debris and dust. Now you can install the new tub drain. Be sure to put the gasket and washer included in the drain kit around the opening in the tub.

Apply plumber’s putty along the edge of the drain, then place the new drain into the opening. Tighten the bolts, connect the drain line, and then turn the water back on. After checking for leaks, you are all finished!.

Does bath water and toilet water go down the same drain?

Yes, bath water and toilet water generally goes down the same drain. In most homes, the water from toilets, sinks, showers and baths are all connected to the same plumbing system and eventually run into the same drain.

This is because the wastewater system needs to be able to accommodate a large volume of water at one time and the only way to do this is by them connecting to one drain. Furthermore, the water from each source is treated the same way by the sewer system before being emptied out into the sea or a waterway.
