5 Signs of Reverse Osmosis Tank Bladder Rupture

Reverse osmosis is a healthy drinking water system, but an issue with the tank’s bladder can be very problematic. Low water pressure, bad tasting water and water leaking from tank are often the most visible signs of a ruptured tank bladder.

In this article, we’ll go through the 5 most common signs of a faulty reverse osmosis tank bladder.

1. Reduced Water Pressure

The most common sign of a ruptured bladder is low water pressure. Low pressure can be due to a leak in the tank and an internal rupture of the bladder.

Suppose there are leaks on any part of the system. These will reduce how much pressure is coming into your home and how quickly it comes out after being treated.

First, check that all filters are clean. Then, check the pressure gauge on the tank. Use this gauge to figure out if the pressure is too low. It may be a good idea to replace the membranes if it is.

Ensure that you have enough storage space for your reverse osmosis system to hold enough water for its operations. If you don’t, you may need to increase the size of your storage tank so that there is more room for the water stored in it.

2. Foul or Salty Tasting Water

If you are experiencing a salty or foul taste in your drinking water, it could signify a ruptured tank bladder. Salty water is due to the water retaining the taste of previous contents within the tank.

The bad taste can arise from the dissolved minerals found within your reverse osmosis system’s piping system. This problem could happen from several factors. The bladder could have been punctured, so it will need to be replaced.

The bladder could have been old and worn out, so it was just time to fail. As the tank ages, the rubber tends to break down and cause the bladder to become vulnerable to damage. This wear and tear can cause a ruptured reverse osmosis tank bladder.

Also, there could be a leak in the line. Leaks won’t allow water to pass through, so you might want to check the connections on the rest of your plumbing.

The solution to this problem is simple: replace your tank bladder. If you find that replacing it does not solve the problem, then there may be something else wrong with your tanks, such as a faulty membrane or an incomplete installation of parts like valves and filters

3. Water Leaking From The Bottom of The Tank

Your water may be leaking out of the bottom of the tank. Leaks can signify that the bladder in your reverse osmosis system is ruptured and needs replacement.

It is crucial to address this issue as soon as possible to avoid running out of water or having mold grow in your home.

If there is a hole or crack in your tank’s bladder, there will be an immediate leak from that area. However, if there are no apparent holes or cracks on either side of your tank lid (or anywhere else), it may not be a problem with damage caused by age.

Instead, there might be something else causing these issues, such as poor installation.

If the tank is leaking, turn off the water supply first, then start the pump to empty the tank.

Next, remove the screws that hold the casing in place. Take a close look at the bladder to see if it is cracked or damaged. If it is, replace it and then reassemble the tank and reinstall it.

4. Excess Air in the RO System

The bladder has likely ruptured if you notice excessive air in your RO system. Air can cause a whole variety of issues in the reverse osmosis system. Air will cause excessive wastewater, depletes the water system, and causes harm to the membrane.

The first step to removing this excess air is to use a vacuum pump. This simple process can be done at home without any tools or experience necessary.

Simply remove the cap on top of your membrane housing and place a clear hose into the hole where water would typically come out.

Then, connect another clear hose to your vacuum pump and begin sucking out all of that extra air from within your RO system. Be sure not to suck too hard, though—you don’t need all of it removed! You just need enough so that normal flow resumes again from the faucet.

5. Slow-Moving or Stagnant Water

If you notice your water is moving very slowly, that’s a sign that the bladder has ruptured. The bladder is responsible for moving the water from one side of your tank to another, so if it’s not working or isn’t in place anymore, your system will be off-balance and may cause damage.

If you have a slow-moving tank, but no leaky cracks or holes are visible on either end, something inside has shifted out of place and could prevent proper drainage.

A quick fix would be to remove all components from inside your RO unit (such as filters and membranes). Then, reinsert them into their original positions to solve any problems caused by misalignment.

Prevention Tips

The first thing to do is to check that the tank is filled with filtered water. If the tank is not filled correctly, the bladder will stretch from the pressure of the water, and that can cause it to burst.

It’s essential to check that the tank is filled correctly before each use to avoid other issues. It’s also important to check that the filter will adequately protect you against the contaminants in the water.

If the filter is not going to do the job, then you might as well not even use the water and save yourself the hassle. Lastly, make sure that you turn off and unplug the machine when not using it.
