Penguin Toilets Reviews

The Penguin Toilet could come in handy if you have a toddler or an elderly family member who consistently blocks a toilet and keeps flushing, creating flooding messes. The facility provides exceptional defense against backed-up toilets overflowing.

The Penguin toilet has a secondary drain tube inside the bowl towards the top that permits water to flow from the bowl when it becomes blocked without going over the top of the toilet bowl.

This post delves into Penguin toilets, their pros, cons, and answers frequently asked questions.

Here’s an in-depth review of the Penguin toilet.

Are Penguin Toilets Good Quality?

Penguin toilets are good-quality pieces created to drain waste into a secondary drain route. The brand installed additional protection from overflow with the help of this secondary drain system. 

It may be installed during new construction or used as a direct replacement for all regular toilets. You don’t need to repipe or upgrade the current plumbing system. 

Place the new Penguin toilet after removing the old one.

The benefit of Penguin Protection Technology targets blind people and other people who are physically or mentally disabled. 

The units come in ADA-compliant and non-compliant heights.

Penguin toilets garnered massive popularity and cemented their place among top-tier toilets, and scooped the Best of KBIS People’s Choice Award for 2011 went to Penguin Toilets Model 524. 

As the only facility with integrated overflow prevention using a secondary drain mechanism, Model 524 stands out. With a Fluidmaster, a 3-inch flush valve, a 1,000-gram MaP test result, and a WaterSense rating of 1.28 GPF, the Penguin Model 524 deserve a spot among top-quality toilets.

However, some buyers question where the water goes if a blockage occurs downstream of the toilet. It may be inconceivable for you to imagine water going around the obstruction.

To counter this, Penguin toilets feature separate drains that feed into the closet bend at the floor level. Water will avoid most blockages in the trapway above the floor, thus affirming that Penguin toilets are good quality.

Penguin Toilets Review: Features

Penguin toilets employ the primary overflow holes, secondary drain system, overflow trap, and wax ring at the bottom of the toilet. Let’s look at each one of them:

Primary Overflow Holes

If there is a blockage and the toilet backs up, the water will rise until it reaches the main overflow openings. Water then enters the sanitary main after draining through the secondary system and avoiding the main trap.

Secondary Drain System

If the primary overflow holes get clogged, the water will rise until it reaches the holes beneath the rim. The water then flows through a concealed inlet into the secondary drainage system and drains into the sanitary main, yet again guarding against an overflow. The mechanism protects against overflow in two ways. 

Overflow Trap

To maintain your toilet’s hygiene, blast the secondary drain with water upon each flush. 

Bottom View

Insert the wax ring on the bowl’s bottom and place the bowl as directed. You won’t need to replace or repipe the current plumbing system. 


Penguin toilets come with a limited 5-year warranty. 

How Penguin Toilets Work

The tank of the Penguin Toilet features readily accessible Fluidmaster components. The distinguishing feature is a separate drain pipe cast in the bowl that resembles an overflow on a bathroom sink.

When the water level in the bowl gets too high, ready to overflow, three holes in the back top area of the bowl let water flow through them. The water drains down a fully independent, trapped drain and empties into the drainage pipe below the toilet.

If the three holes get blocked with paper or other waste, the holes under the toilet’s rim serve as drains. Even if the bowl is frequently flushed when blocked, this unique drain design will prevent overflow.

How To Adjust Water Level In Penguin Toilets

  • Turn on the water supply and immerse the float cup in water for about 30 seconds. 
  • Turn the water level adjustment rod to the desired level, then raise or lower the float cup. 
  • Flush the toilet three times to set the “No Overflow” mechanism once the water level is consistent with the marking in the tank. 

Toilet traps start self-priming when the prime forms. The unit won’t need additional priming. 

How To Maintain Penguin Toilets

When cleaning a Penguin toilet, use mild soap and water, followed by a good rinse in clear water and a soft towel to dry it.

Avoid using cleaning agents, detergents, or disinfectants in aerosol cans. Additionally, do not use abrasive pads or scouring powders to clean the toilet seat. 

The “No Overflow” provision on this toilet needs little to no maintenance. The back of the toilet bowl contains three holes through which water in the bowl will escape if the main trap ever becomes clogged. 

Put an inconsiderable amount of water into a reservoir with each flush to keep sewage gas from rising through these openings. The water could smell bad if you don’t flush the toilet for a long time (like during a trip). Flushing brings fresh water into the tank.

NOTE: Experts advise against using in-tank cleaners. Chlorine products (calcium hypochlorite) can severely hurt tank fittings, resulting in leaks and property damage. Penguin will not be accountable for tank fitting damage incurred by chlorine-containing cleaners (calcium hypochlorite). 

How To Troubleshoot Penguin Toilet Problems

Always keep sand and rust out of the system. Check that the water supply is off.

Lift the arm and rotate the top and arm 1/8 turn anti-clockwise, pushing down slightly on the cap. Turn the water supply on and off multiple times while keeping a container over the uncapped valve to minimize splashing. 

Cut off the water supply. Engage the lugs and turn 1/8 turn clockwise to reinstall the top.
