What to Consider Before Purchasing the Best Pressure Assisted Toilets

1. Flush Rating

Every pressure assist flushing system comes with a flush rating, and this indicates how fast the pressure-assist toilet will perform; therefore, you always need to check the flush ratings. The flush rating depends on the flushing technology, with some of the most popular technologies being power flush and pressure-assisted siphon jet.

For homesteads with low water pressure, you can use a battery or electric pump to increase the tank pressure like most pressure-assisted toilets. The best pressure-assisted toilet will have a flush rating of between 1.1 and 1.3 gallons per flush (GPF), but some of these flash ratings go up to 1.6 gallons per flush which is still the ADA compliant range.

2. Noise Level

While pressure-assist toilets work effectively, they produce a lot of noise in the process, and the noise is the small price you have to pay to get the powerful performance. However, some companies like American Standard and Kohler usually make quieter models, and as time goes by, the technology continues to advance. Therefore try to choose a pressure-assist toilet because it will produce less noise during operation.

3. Convenience

The best pressure assists toilet can have a few things that will improve the experience from a toilet kit; for example, a soft-closing lead will close behind and slowly avoid banging that will give elderly folks and kids some shock. Also, for convenience, there is a dual flush mechanism that helps in conserving water, and some toilets have a single unit.

However, when a toilet kit comes with a complete set, it causes less hassle and considers a stain-proof and scratch-proof vitreous china bowl, and in this way, your toilet will remain spotless with a powerful flush.

4. Type of Flushing

a). Gravity Feed Toilets

These gravity-fed toilets use a flush valve that functions depending on the gravity, and then water is released from the water tank to the toilet bowl and then flushed the solid waste to the drain. Notably, the gravity toilets can perform with low water pressure of 10 psi, and some of these toilet models feature a narrow flush valve ranging between 2 and 2.5 inches. The gravity feed toilet is popular because it generates less noise when it's in use than other pressure-assisted models, but they also come at a very high price.

b). Pressure Assisted Toilets

These pressurized toilets function by compressing water and pressurized air together in the tank compartment, which will generate pressure, and this mechanism pushes the waste down to the drain. These pressure toilets are a suitable fit for large families and they very noisy yet more expensive, but they are quite effective.

5. Water-Saving Technology

Your choice of the best pressure-assist toilet should have optimal performance, and it should use the least water, reducing your monthly water bills, and you should ensure it stays below 1.6 gallons per flush to help save energy. So choose pressure-assisted toilets that will maximize efficiency and flushing performance with a minimum amount of water.

6. Shape and Color

The shape and space are important because a round bowl may be difficult to fit than the elongated bowl shape. Still, the elongated toilet seat is ergonomic and will offer maximum comfort and ample room when in use. Also, when it comes to the one-piece vs. the two-piece toilets, the two-piece toilet is a sleek option with the bowl and the tank and two separate parts. Even though it might take a while to install them together, they give flexibility and are cheaper than the one-piece pressure-assist toilet.

On the other hand, for color, choosing the colored pressure-assist toilets gives your design and space some class, but most pressure-assist toilets can be found in white colors with the best resale value when selling your home.

7. Flushing System

Different flushing systems work with both one-piece and two-piece toilets. However, a single flush toilet and a dual flush toilet have varying water consumption amounts, and in some states, you can install dual flush systems for solid waste or liquid waste.

While single flush systems only use a specific amount of water with each flush that minimizes monthly bills, you can purchase the water-saving single flush systems to minimize your water consumption and have efficient flushing. In addition, other systems allow you to change the flush mechanism if your cistern breaks, which will save money, time, and water usage compared to replacing the whole toilet.

8. Warranty

Since purchasing a high-pressure assist toilet is an investment and some companies are still a new technology, you should consider getting one that packs a long warranty. On top of the long warranty, you should have policies in the document favoring you more to avoid worrying about breaks.
