6 Proflo Toilet Problems & Solutions

Proflo toilets are water-efficient, comfortable, flexible, and highly affordable toilets hence a great addition to your toilet. However, like other toilets, they can develop issues, so before getting yourself one, know the common Proflo toilet problems.  

You may experience clogging, continuous running, and the toilet bowl emptying slowly if you have a Proflo toilet. To restore the toilet’s functionality and efficiency, you must fix these issues should they arise. 

This post offers a comprehensive guide to troubleshooting and fixing Proflo toilet problems. 

Proflo Toilet Problems 

The table below gives an overview of Proflo toilet problems and how to fix them. 

Problem Possible Cause Recommended Fix
1. Clogging Toilet paper and other foreign items Use toilet auger
2. Clogged toilet jets Accumulation of mineral salts and bacteria Use vinegar solution and diluted bleach
3.  Toilet always running
  • Dirty or damaged flush valve
  • Leaking in the float ball
  • Faulty lift chains
Clean or replace the flush valve

Replace the float ball

4. Bowl emptying slowly
  • Partial blockage of the flush handle
Plunge to clear the blockage


1. Clogging

Clogging is a prevalent problem among toilets, and Proflo occasionally becomes a victim too. It stems from stuffing tissue paper and other foreign materials in the toilet drain. 

The objects accumulate in the sewer line and cause other problems, such as the Proflo toilet not flushing properly. 


  • Use a toilet auger or plunger to unblock your toilet and sewer line. 
  • Alternatively, contact a professional plumber. 

2. Clogged Toilet Jets

The accumulation of mineral deposits and bacteria on the toilet openings will impede flushing by reducing its power to force waste down the drain. 


  • Use a toothbrush to remove mineral deposits. 
  • You can use vinegar solution and diluted bleach to dissolve mineral deposits and kill bacteria. 

3. Problems With The Chain And Toilet Handle

Apart from clogged toilet jets and clogging, defects in the chain and the toilet handle can cause flushing problems. A too-long or too-short chain will lower your toilet’s flushing power. 

The chain connects the flapper to the toilet handle, thus implying a disconnection between the flapper and the handle resulting from a broken chain will cause problems. 


  • Replace the broken flapper chain and reconnect the toilet handle and the flapper.
  • Adjust the chain length. 

4. Proflo Toilet Keeps Running

A toilet that keeps running wastes water and inflates your water bills. This problem could arise from a defective flush valve. 

The flush valve allows water into the tank after flushing the toilet. Therefore, a defective (dirty or damaged) valve will cause your Proflo toilet to run continuously. 

An overflow tube regulates the amount of water getting into the tank. However, it can only do this when you set it at the correct height; otherwise, water will flow continuously into the tank. 

Moreover, faults in the lift chains, fill valve, float ball, and pressure-assist valve will keep your toilet running. It is also worth mentioning that a running toilet doesn’t stop independently, meaning you have to address the problem as soon as you detect it. 


  • Start by examining the lift chains. 
  • Replace the float ball if it is leaking. 
  • If the solution doesn’t correct the problem, check the water level in the tank and adjust it. 
  • Clean or replace the dirty or damaged pressure-assist valve. 
  • Check the height of the overflow tube and make necessary adjustments. 

If the problem is with the flush valve, follow the procedure below to correct it:

  • Cut off the water supply to the toilet. 
  • Soak the remaining water with a towel or piece of cloth. 
  • Disconnect the flapper and remove the tank-to-bowl bolts. It will help you remove the flush valve. 
  • Take the tank off your toilet to expose the toilet-to-bowl gasket. 
  • Get a partner to help you loosen the flush valve nut. 
  • Next, restore the tank-to-bowl gasket after putting in the new flush valve and tightening the flush valve nut.
  • Place the toilet tank back in its original place and reassemble the tank-to-bowl hardware. 
  • After this, check for water leaking at the bottom of the toilet. 
  • Test the replacement flush valve by flushing the toilet. 
  • If your Proflo toilet keeps running, then chances are you didn’t install the flapper or tank-to-bowl gasket correctly. 

If the fill valves cause your toilet to run continuously, the steps below will help you curb water wastage:

  • Turn off the water supply to the toilet tank. 
  • Flush the toilet to drain the tank. 
  • Clean up and dry the remaining water using a cloth or a towel. 
  • Disconnect the water supply line with channel locks. 
  • Remove the old fill valve by loosening the locking nut on the toilet tank’s bottom and drawing the fill valve mechanism out.
  • Place the old fill valve in a bucket or sink. 
  • Set the height of the replacement fill valve to fit the Proflo toilet tank and the recommended water level. 
  • Plug the valve’s threaded end into the toilet tank bottom. 
  • Establish a watertight seal by securing the threaded end of the valve to the tank. A locking nut can serve that purpose. 
  • Restore the water supply and turn on the water.

5. No Water In The Tank

After relieving yourself, the next course of action is flushing the waste down the drain. That may be difficult if your Proflo toilet tank is waterless. 

If you are experiencing this, the issue could be with the float ball, the trip assembly, or the fill valve. Let’s take a look at each of them and their solutions. 

a) Problems With The Float Ball

The float ball prevents water from rising above a recommended level, especially in older toilets. You need to check the fixture regularly to ensure the ball doesn’t sit too low since that will mean the toilet tank gets insufficient water. 


  • Remove the lid of your toilet tank. 
  • Make a slight upward bend in the float arm. 
  • Set the float ball at a higher level after raising the float arm. 
  • Replace the float ball if it remains in a lower position. 

b) Misaligned Or Blocked Trip Assembly

Manufacturers attached the trip assembly to the toilet handle to aid in the flushing. However, a blocked or misaligned trip mechanism won’t perform as intended.


  • Lift the toilet tank cover. 
  • Examine the trip assembly. 
  • Repair or replace the mechanism, depending on the severity of the damage. 

c) Issues With The Fill Valve

The fill valve’s role in modern toilets is similar to the float ball in classic models. A malfunctioning fill valve can also deny your toilet tank water. 


  • Remove the toilet tank cover. 
  • Locate the adjustment screw on the float cap. 
  • Turn it clockwise t raise the water level. 
  • Flush the toilet and check the water level after refilling the tank. 

6. Proflo Toilet Bowl Emptying Slowly

A faulty toilet handle and partial blockage are the main culprits behind this problem. While flushing the problematic toilet, cross-check it with other fixtures in the apartment, paying close attention to gurgling sounds. 

Gurgling sounds signify your waste lines lack air to enhance water flow, which carries waste to the sewer line. 

The toilet bowl emptying slowly can also arise from flushing valves. 


  • Plunge the toilet to clear the partial blockage. 
  • Adjust the length of the flush chain. 
  • Climb the rooftop and clear the vents.
