In many homes, gas columns are a necessary appliance because they supply hot water for a variety of domestic requirements. Performance problems with an appliance can arise from a gas column’s membrane wearing down or getting damaged over time. Even though changing the membrane might seem difficult, it’s a task that can be completed with the correct information and resources. We’ll show you how to replace the gas column membrane in this guide, giving you the tools you need to effectively maintain the heating and hot water system in your house.
Understanding the function of the membrane in a gas column is essential before beginning the replacement procedure. An essential part that controls gas flow and guarantees secure and effective operation is the membrane. Wear and tear on the membrane can cause issues like low water pressure, irregular heating of the water, or even gas leaks. You can avoid possible risks and restore the functionality of your gas column by replacing the membrane as soon as possible.
Getting the required instruments and supplies is one of the first steps in replacing the membrane. Typically, you’ll need a screwdriver, wrench, replacement membrane kit (which contains the membrane and any accessories), and if visibility is poor, a flashlight. To prevent any mishaps or injuries, make sure you cut off the gas supply to the column and let it cool fully before beginning the replacement procedure.
Once the column has cooled down and the gas supply has been cut off, you can start disassembling the unit to get at the membrane. Using the right tools, begin by taking off the gas column’s outer shell. After removing the casing, find the membrane assembly, which is typically located close to the burner assembly. Remove any screws or other fasteners holding the membrane assembly in place carefully, being cautious not to harm any nearby components.
Once the old membrane has been removed, carefully check the surrounding parts for wear or damage. Cleaning up any buildup or debris that may have accumulated inside the gas column is also a good idea at this time. You can install the new membrane in accordance with the manufacturer’s instructions once the area has been thoroughly cleaned and cleared of debris. To guarantee optimal performance, take care to precisely align the membrane and firmly secure it in place.
Reassemble the gas column in the same order that it was disassembled after the replacement membrane is in place. Before resuming the gas supply, make sure that every part is firmly in place. It is crucial to test the gas column after reassembly to make sure it is operating properly. Examine the area for any leaks, strange water heating patterns, or other problems that might point to a problem. If everything appears to be in order, you can relax knowing that you have successfully replaced your gas column’s membrane, guaranteeing your home’s continuous supply of hot water.

How the membrane works in the column – what it is responsible for
The gas water heater’s water regulator is essentially its brains. The rubber gasket (diaphragm) installed in the node controls the supply, opening and closing the gas supply to the burner. The membrane in the gas column functions according to the following principle:
-
The water regulator is a metal unit with an empty cavity divided into two parts by a diaphragm.
Depending on the water heater model, the membrane device on the gas column may look different, but the fundamental working principle is always the same. The diaphragm ages, loses some of its elasticity, or tears over time, which causes the heat generator to fail.
In a flow gas water heater, the burner device’s automatic ignition and gas supply are handled by the diaphragm. The equipment’s performance is immediately impacted when the water regulator (frog) fails.
Types of diaphragms for columns
The gas water heater’s diaphragm is a circular gasket composed of silicone or black rubber. The column manufacturer may have used metal or hard plastic components on the diaphragm. A few diaphragms are shaped differently.
European manufacturers of gas water heaters use difficult-to-fake diaphragms. For instance, the so-called "eight" is installed in the Vaillant MAG diaphragm or the Electrolux GWH, and it is installed in the Ariston Fast GIWH. Such a gasket will only be available for purchase from an authorized service center. The diaphragm for the European water heater’s frog costs between 200 and 500 rubles. In contrast, the cost of a repair kit plus plastic parts for a domestic NEVA Lux 5013 (5016) is only 150–200 rubles.
Regarding the substance used to make diaphragms, there are various varieties:
-
Black rubber membrane – the classic look. Most manufacturers prefer to make gaskets specifically from black rubber. This diaphragm will last 7-8 years, provided that it is not defective.
The diaphragm that is used can be determined by looking through the technical documentation that comes with the flow heater or by disassembling the water regulator.
Signs of a faulty diaphragm in the column – how to check it
Diaphragm wear is fairly simple to assess. There are indicators that suggest the diaphragm is failing. When performing maintenance on the water heater, masters take note of the following:
-
Water regulator leaks – in normal condition the gasket completely covers the part of the unit where water circulates. Drip starts only if the membrane is torn.
-
Membrane leaks – provided the leak is small the column will work for a while. Over time, water will start to drip out of the regulator.
Low water quality causes the heater’s membrane to break down. The surface loses its elasticity and becomes rough. Microcracks that let water in are created over time in the material.
Can you make a membrane yourself and from what?
Make sure that a failed diaphragm is the cause of the burner device’s poor performance before beginning any repairs. Dead batteries and igniter issues can be the source of a water heater malfunction. Repairing the water regulator should only be done after ruling out any other malfunctions.
Frequently, diaphragm issues come on suddenly. A suitable gasket takes a few days to arrive. You can make or repair the diaphragm on your own in order to use hot water during this period.
Rubber with a thickness of 1.5–2 mm works well as a temporary gasket. Some use thick household gloves or an old car camera as a billet. A punch, which can be easily made from a metal tube, is used to create holes for bolts and bypass channels.
Using the old diaphragm as a template, the new diaphragm is cut out. You can use a patch to seal the diaphragm as a temporary solution. Following the repairs, the column will function for a while, long enough to obtain the factory diaphragm.
Although replacing the gas column membrane may seem like a difficult undertaking, you can do it yourself if you have the necessary skills and equipment. You can make sure that your gas column keeps working effectively and safely by following these steps.
Prioritizing safety above all else is imperative when handling any gas appliance. Make sure the column’s gas supply is turned off and that it has had time to cool fully before starting. Furthermore, make sure you have the goggles and gloves you need on hand in order to shield yourself from any potential hazards.
It’s not too difficult to replace the gas column membrane once you’ve taken the appropriate safety precautions. To access the internal components of the column, start by removing its outer casing. You might need to consult the manufacturer’s instructions to ensure proper execution of this task.
Find the old membrane inside the column after removing the casing. Remove it carefully, paying attention to its placement and any connections it might have with other parts. After that, just slide the new membrane into its designated spot, making sure it is seated firmly and correctly aligned.
Reassemble the gas column’s outer casing after the replacement membrane has been installed, then turn back the gas supply. Make sure the column is working properly by carefully testing it after everything has been put back in place. If problems arise, review your work again and seek professional assistance if needed.
You can replace the membrane in your gas column on your own, without the help of a professional, if you follow these instructions and use caution at all times. You’ll save money and time by doing this, and you’ll feel good about yourself for being able to take care of simple home maintenance.
