The Combination Valve, sometimes called the Pressure Reduction Valve or Cold Inlet Valve has a number of functions and combines different valves into one fitting. A combination valve contains the following components:
If the water flow at the tap reduces, it could be caused by one of the following:
Please Note: We do not recommend that anyone without the right experience and training attempt to diagnose and repair valve leaks or water pressure problems with an unvented cylinder. Only a trained professional should handle these issues, as dangerous situations could occur, causing serious injury. We highly recommend that you contact a professional provider like EasyFlow to handle all diagnoses and repairs.
In addition, you might notice water dripping into the tun dish. If the drip is cold, this will be from the expansion valve and might be a result of either a fault with the valve, caused by over pressure as a result of the heater not being serviced. Or by the fact that the unvented water heater is overdue for a service. In the latter case the drip is being caused by the water expanding as it is being heated and as the air gap or the charge I the expansion vessel has depleted the additional volume of water has nowhere to go and forces the valve to open under pressure.
Combination Valves come with a manufactures warranty of 12 months, but typically last for between five to seven years if they are serviced on a regular basis. When Combination Valves / Cold Water Inlet Valves are fitted with a new water cylinder, they should be installed above, or at least near to the top of the cylinder. This helps with servicing, replacement and reduces the risk of leaks if there is a fault with the valve. If the valve is leaking and the water supply is turned off, the valve will continue to leak if it is positioned near to the bottom of the cylinder.
If the valve needs to be replaced it must be replaced with a valve which is rated at similar pressure setting as the once prescribed by the manufacturer. This is for safety and for performance. With older cylinders, the original valves are often either not available or extremely expensive, due to the fact that they are no longer made. It is acceptable to use an alternative valve, providing the sizing and the pressure settings are consistent with the original.
The Benefits Offered by the Right Maintenance Plan
As mentioned, while these valves come with a warranty of just 12 months, a little bit of professional care each year could extend that many times over. Just one instance of professional maintenance every 12 months could extend the lifespan of a Combination Valve or Cold Water Inlet Valve by up to seven years. That does more than just save you time – it also saves hassle and money. It provides a significant amount of peace of mind, and ensures that you have a constant store of hot water that you can rely on for bathing, washing dishes and more.
At EasyFlow, we offer professional Maintenance Plans designed to ensure that your hot water heater lasts as long as possible and that you are able to reduce the number and cost of potential problems you experience with yours.
If you have an unvented thermal store, you already know that your insurer requires an annual inspection of the system in order to provide you with cover. Failure to do so can put your protection in jeopardy. Our Maintenance Plan includes an annual inspection that satisfies insurer requirements, ensuring that you are able to protect your home and belongings.
Our Maintenance Plans also include professional service from some of the most experienced professionals in the industry. We carry spare parts for the most commonly installed hot water heaters in our vans, ensuring that if there is a part failure, we can make an immediate replacement.
However, if your hot water heater is very old and has begun to corrode, it may not be serviceable. We cannot service or inspect unvented water heaters that have begun to degrade, as they present safety threats. Our professional service representatives can inspect your system to determine its condition and then make recommendations if a replacement is needed. We can even install the new hot water heater for you, ensuring that everything is connected and working properly and that you have a constant supply of hot water.
We also cannot service any hot water heaters if there are no available spare parts. This situation is more common than you might think, as many hot water heater manufacturers only design the cylinders, not the components that the cylinder houses. If the manufacturer of a component stops manufacturing it or goes out of business, and there is no comparable alternative, we cannot service that water heater. However, we will be happy to speak with you about your options.
