Types of Toilet Water Supply Lines

Types of Toilet Water Supply Lines

A toilet supply line connects the water in your wall pipes to the toilet tank. It is usually a flexible tube with a nut on each side.

There are two major types available:

  • Plastic/Rubber
  • Metal

1. Plastic/rubber supply lines

These are usually white. They are quite common because of their inexpensive nature, but more and more homeowners are turning away from them because of their vulnerability to leaks and failure to last.

Advantages:

• Lightweight and easier to install.
• Inexpensive and budget-friendly.

Disadvantages:

• Can result in great losses in case of water leaks.
• They don’t look great.

2. Metal supply lines

These are usually silver in color. Though they are a little more expensive, they are increasingly becoming common due to the high level of safety they offer against water leaks and damage.

You can save a few bucks by getting a plastic supply line. However, by getting a metal line, you can save thousands by avoiding water leaks.

Advantages:

• They look more elegant and appealing in the bathroom.
• They last a long time.
• They offer greater protection against leaks and water damage.

Disadvantages:

• They are a little costlier (but well worth it).

Our Recommended Product of The Best Toilet Supply line in 2022

1. Fluidmaster B1T12CS CLICK SEAL Toilet Supply Lines

A perfect seal is one that is not too tight or too loose. The best thing about Fluidmater’s Click Seal connector is that it lets you know when you have the perfect seal. Working just like your car’s gas cap, this product prevents the fill valve shank and the connector nut from overtightening or cracking.

What most people find great about this connector is how seamless it is to install. You only have to twist it. Once you’ve done that, you will hear a click, and that tells you that your toilet water hose is sealed.

Another benefit is that you don’t need too many tools. You only need an adjustable wrench. Let’s now talk a bit about the design. The Click Seal is made of a tough polymer that is covered with braided stainless steel, so you can expect it to last decades.

On both ends, the hose is fitted with a female-thread nut. One of the ends has a 3/8 compression thread that’s to be installed on the shut-off valve. On the other end, the connector is fitted with a 7/8 ballcock thread that is to be connected to the fill shank.

The hose is 12 inches long, which is ideal for most toilet installations. Owing to its high quality, durability, and ease of use, the Fliudmaster Click Seal is a good quality toilet hose connector to purchase.

Highlighted features:

What to Look for Before Buying The Best Toilet Supply Line

flexible toilet supply line

A toilet water supply line moves fresh water from the pipe in the wall to your toilet tank for flushing. However, not all supply lines work properly.

A bad line will leak or burst and flood the place, or cause you to run into other undesirable issues. If you’re seriously looking for the best toilet connector, here are a few considerations to make.

i. Hose size

water supply connector

This is perhaps the first thing most plumbers and homeowners consider. Is the connector size suitable for the fittings? To know the answer to that question, you need to measure the distance between the fill valve on the toilet tank and the angle stop on the wall.

The common hose lengths are – 9, 12, 16, and 20 inches. There is an easy way to get the right size – simply check the length of your old supply line and replace it with a similarly sized line.

That being said, some folks want to get a longer hose for various reasons. Perhaps you want to create a longer loop or you want to introduce a new toilet fixture that will need a different size.

The pipe diameter is also worth considering, although it is not as important as the hose length. Usually, the smaller the toilet supplies pipe diameter, the more pressure, and vice-versa.

ii. Nut diameter

Ever bought a supply line with nuts so small or so large that they couldn’t be used? That’s a blunder you want to avoid. You can check your old line’s nut sizes and get a new supply line with identical nut sizes.

Or, you can use a tape measure to check the correct diameter. When talking about the nut diameter, there are two nuts to consider here. There’s the smaller nut that will connect to the wall, and there’s the larger nut that will connect to the toilet tank.

Common sizes for the smaller nut include 3/8 inch and ½ inch. Conversely, common sizes for the larger nut include 7/8 inch and 1 ¼ inch.

iii. Material

Before purchasing the product, check the material it is made of. There are three major options – plastic, rubber, and metal. Plastic is very cheap but it doesn’t last and it is prone to leaks. Rubber is better, but it is still vulnerable to leaks.

If you want the best option, go for metals such as stainless steel and brass. Supply lines made of metal can last decades. As you’re dealing with water, an agent of rust, it is ideal to get a line made of stainless steel as this material is resilient against rust.

Normally, the tube inside is made of rubber but it is enclosed with braided stainless steel for longevity. The nuts can be made of plastic but metal ones are better as they last longer.

FAQs

1. What is the purpose of a toilet supply line?

A supply line is a tube structure with a nut on each end. Its purpose is to carry freshwater from the pipe in the nearby wall to the toilet tank to be utilized for flushing.

5. How long do toilet supply lines last?

The durability of a supply line mainly depends on its material. Plastic and rubber lines hardly last 10 years, and as a rule of thumb, they should be replaced every three to five years to protect your home from leaks.

On the other hand, metal lines, especially those made of stainless steel or brass, can last decades. It can be 50 years before these high-quality toilet supply lines need to be replaced.

3. What sizes are toilet water supply lines?

Supply lines come in a variety of sizes. There are two main sizes to consider – the length and the nut sizes. Hose lengths vary from 6 inches to about 20 inches although you get bigger sizes. In contrast, the nut size ranges from 3/8 to 1 ¼ inch.

4. How do you install a toilet water supply?

These days, it is quite easy for anyone to install a toilet supply line. With a good line like the FluidMaster Click Seal, you don’t need tools. You simply use your hands to turn the compression nut and connect it to the angle valve on the wall.

Then, you turn the ballcock nut and connect it to the toilet tank inlet. A wrench might come in handy for making the connection tighter.

Final Word

If your water supply line is worn, or if it’s been in use for a long time, there is a need to replace it. Fortunately, there are many options to choose from as I have illustrated above.

Furthermore, gone are the days when you needed a plumber to do the job for you. Now, with the best toilet supply line, such as the ones from FluidMaster, you can do the installation in minutes.

You don’t even need tools except perhaps for an adjustable wrench. As you choose your next supply line, remember to look for the right size for your fittings.
