This saves you the expense of frequent coolant replacements and possibly the expensive cost replacing a radiator or other components of the cooling system. However, a radiator coolant overflow tank can prevent this problem before it even starts. When rust has formed inside the radiator, you will have no choice but to flush out the system and replace the antifreeze. That air will result in the formation of rust in the cooling system when it comes into contact with the metal in the system. Related: Overfilled Your Coolant? (What Can Happen) When the coolant cools after the engine has been turned off, it contracts in volume which will result in a drop of temperature and pressure inside the radiator allowing the air to enter the radiator through the radiator cap. This information would help you understand the reasons behind the overflow of your cold water tank or hot water tank, and know how you can get the issue resolved.Click Here to chat online with a verified mechanic who will answer your questions. Seek the assistance of experienced technicians specializing in fixing hot water tank/water heater issues to get your TPR valve checked and replaced. This would also eliminate the risk of any major hazards like explosion of the water tank. It’s crucial to check your TPR valve annually and replace it when necessary. This may also happen if mineral deposits build up within the valve. This may happen if the valve has become weak over time. If TPR valve begins overflowing and has a constant drip, it’s a sign of malfunction of the overflow valve. If TPR valve malfunctions, pressure within the tank may lead to explosion of the tank, resulting in serious damages to your home. TPR valve is fixed with a discharge pipe which targets the overflow at the ground or floor where the water heater is located. At times when pressure builds up within a water heater, it is released by the TPR valve. Overflow of a hot water tank (also called a hot water heater) should be taken quite seriously to prevent any major hazards (like explosion).Ī water heater includes a safety feature known as “temperature pressure relief valve”. The solution is fitting a quality non-return valve at hot feed pipe to shower or tap.Īs the solution, hot feed pipe to shower or tap should be fit with a quality non-return valve. Alternatively, the reason may be a pre-existing mixer shower or mixer tap that has developed an internal leak. In case the cistern overflows only when a certain mixer shower or mixer tap is open, this is certainly the cause then. The mains water at high pressure displaces the water at low pressure from hot water cylinder, forcing it back into cold water cistern. If you have recently installed a shower with mixer valve or new mixer tap which is fed by mains, this might be the reason behind the issue. This situation depends largely on your plumbing system’s configuration. A good quality, brand new valve will be reliable, cost-effective, and will offer you the peace of mind of getting the problem fixed.Įven when the ball valve works correctly, still a cold water cistern may overflow. General wear & tear may lead to chipping or splitting of the valve seating edges, and cracking or splitting of the washer.Īlthough it’s cheap to replace the valve seating and washer, it might be easier and simpler to replace the complete valve. Water flow into the cistern is stopped by this.įoreign materials like limescale, dirt, grit, or damage to the washer or the valve seating may prevent the water tight seal. As the cistern’s water level rises, a washer is pushed onto valve seating by the float – a plastic nozzle within the valve body. This ball valve is responsible for controlling the water level in the cistern through a plastic float sitting on the water surface. The cause most commonly leading to overflow of a residential or industrial cold water storage tank is an erroneous ball valve. The most common cause – faulty ball valve This may be the smaller feed & expansion cistern putting water into central heating circuit or it may be the storage cistern for cold water supplying the cold water bathroom taps and hot water cylinder. If you find water pouring or dripping from a pipe pointing out of the building or from eaves of roof, then a cold water tank is overflowing. 9 Summing Up Overflow of Cold Water Tanks
