Important Things to Consider When Buying No Clog Toilet

The following parameters will assist you in finding the right toilet:

Water consumption

Have you ever wondered about the consequences if 30 percent of residential water is wasted in the bathroom? The impact is not immediate, but it is a threat to our future generation. Well, Researchers showed that toilet systems used the same amount of water two decades ago.

Then, people finally realized that we had to find out better alternatives. A more water-efficient mechanism was invented, which requires 1.28 GPF or less water per flush. Such toilets save at least 20 percent more water than the 1.6 GPF companies. Always prioritize the units having EPA’s WaterSense certification.

Flush systems

When it comes to the flush mechanism, the pressure-assisted ones are unbeatable. They have secondary tanks situated in the main tank. It produces sufficient air pressure for flushing. Their power is exceptionally stronger than all other techniques.

The flow of bulk water cleans the toilet efficiently. It does not face clogging troubles anymore. Some drawbacks are there too. Loud noise generation and high cost are two of them. The gravity-flow flushes are stronger than common approaches but less than the first types. They depend on the world’s gravitational pulling force to empty the bowl. But they are more likely to be clogged.

Installation

Installation phases do not necessarily define the quality of a product. Nevertheless, it matters. Lots of customers neither want to go through a complicated process nor are interested in taking help from plumbers. They arrange the whole toilet setup following the instruction book.

If you are one of them, look for a simple and straightforward product. Some toilets only require the basic arrangements and bolt fittings. We can do this with the right tools. The finished result is the same as the work of an experienced person. On the other hand, if you don’t mind calling a plumber, you don’t have to be bothered about the installation.

Materials

First of all, check the material list. It indicates the basic characteristics and durability of the toilet. Most modern toilets are made of ceramic or a special clay named vitreous china. They are very long-lasting and more costly than other items.

You will notice the differences just by looking at the toilet wall. Non-porous coating leaves a smooth surface. It does not allow stains, molds, mildew, and germs to build up. So, the users don’t have to clean it from time to time. Contrarily, wastes on a porous platform take a long time to disappear even if the flush system is the best. Remember, they save some bucks indeed but cost more later.

Construction

The functions of an item mostly rely on it. The one-piece design offers more benefits than the two-piece. You can choose any style, though. Just make sure that it has a big trapway and flush valve. Without a big flush, quick waste removal is impossible.

Its high force and speed transfer the waste into the drain immediately. You no longer have to flush a couple of times.

Also, the size of the tramway is crucial because it moves everything to the outer lines. While getting a personal toilet, you have options between a round or an elongated bowl. The elongated shape offers more comfort and performs better in fall prevention.

Noise Level

Nobody wants to inform others while doing his private business. We can benefit a lot from a noiseless model. Plenty of toilets implement a flush system that makes loud sounds. If someone is using the bathroom at midnight, it can wake everyone up.

If it owns a rough-closing lid, the situation will be worse. Aside from the sound, it can break the toilet bowl. Therefore, the modern toilet industries discovered a quiet flushing setup and a soft-closing lid with the toilets. Some durable hinges secure the landing of the cover as softly as possible.

Price

It is usual for sellers to demand high prices for good models. For example, toilets consisting of good-quality elements are the best. As the cost of these materials is high, the toilets are expensive. If they have additional beneficial features, it will be more costly.

Once you purchase them, they will serve for a long time without degrading their performance. We never recommend crossing your budget for getting them. Just be sure of getting the best within your price range. Poor-quality toilets can break after a month of use. Then you will have to buy a new one. Don’t be a victim of the trap.

Frequently Asked Questions

Question: What causes my toilet to clog?

Answer: Clogging is the result of multiple things. If excess tissue papers are stuck in the trapway, water can’t go down. Again, people mistakenly drop hard objects on the toilet, such as kids’ toys, toothbrushes, plastics, etc. Every time they flush, it won’t move to the drain line. Instead, more debris wraps around it. These incidents eventually lead to clogging. Low-flow toilets and sewer line issues cause clogging too.

Question: Why does my toilet flush take time to eliminate debris?

Answer: Sometimes, our toilets flush slowly, even though it does not have a clog. However, it is not okay. The toilet may be fine, but the problems can be in some other places. Usually, clogged drains fail to manage the draining procedures and end up affecting the flush system. We suggest taking help from a qualified plumber as soon as possible. Late actions may make the situation worse.

Question: What is the difference between a normal toilet and a dual flush toilet?

Answer: About 20 years ago, studies proved that Americans’ toilets take 1.6 gallons of water per flush. The vast amount made everyone worried, and the manufacturers brought 1.28 GPF versions. An innovative idea came to reduce water usage.

A single flush valve uses the same water for both liquid and solid wastes. But dual flush systems employ different valves for them. One operates for shifting the liquid wastes using less water. The other consumes 1.28 gallons to remove solid particles.

Question: What are the benefits of one-piece toilets?

Answer: We can divide all toilets into two categories based on their formation. A two-piece toilet has a separate tank and bowl. Conversely, they are placed into a solid piece in a one-piece version. Its sleeker design looks nice while offering some benefits.

It hardly takes some minutes to install. Less dirt gathers on it because of not having hidden places. You can wipe off the dust with ease. It does not suffer from leaking or breaking. Overall, it has a long lifespan. Don’t expect the same flushing as well as water-saving opportunities from a two-piece toilet.

Question: How can I be sure that my selected toilet won’t lead to clogging problems?

Answer: A few features mainly determine whether a toilet is more likely to get clogged or not. A clog-proof toilet generally arrives with a wide flush valve. Check for larger valves than standard 2-inch flush valves. Secondly, focus on the trapway size. If it is bigger than 2-1/8 inches, it can remove more dirt at once.

Question: What makes a good flushing system?

Answer: Some exceptions are more potent than regular flushing systems. The most popular option is the gravity-feed model. They operate by the coordination of tank pressure and gravity. It results in a strong flushing action, which raises their demand in both the home and industrial sectors.
