Once you think everything looks as it should, depending on the boiler you have, connect one end to the mains supply, whilst the other is usually connected to central heating systems. r/Plumbing I want to say THANK YOU to all you plumbers out there who save DIYers, like myself. The boiler filling loop is a small braided hose with a valve attached. Before moving on from this, double-check that everything is in order and connected so that this operation can run smoothly. How often should boiler pressure drop? You can check the pressure of your boiler and re-pressurise it yourself without having to call an engineer out. Baxi Potterton. Topping up your boiler pressure is a simple fix and can be carried out without a heating engineer. Open the valves. The volume of your system is fixed, so adding more water increases the pressure. If the pressure is too low or keeps dropping. Tighten the knob (clockwise) and turn the key to the open padlock position. If the pressure reads at 2.75 bar or above, you may need to bleed a radiator to release the pressure and bring it back down to a suitable level. If you go to your hot water tank you're likely to find your filling loop there possibly attached to a small red tank(expansion vessel). Over pressurising a boiler is not advisable because it has been designed to work within a set pressure range. Heres what to do if thats the case. Keep an eye on the pressure gauge you are looking for pressure over 1 bar. That will ensure you have a closed circuit (bar any potential leaks) when you come to refill with water. Repressurising is a delicate process that needs to be done the right way. You need to find the hot water cylinder Opening this valve while monitoring the pressure on the boiler will add extra water to your hot water tank. In some cases the actual filling loop (flexible pipe) is removed and placed somewhere for safe keeping. Our Purpose: We create living space for generations to come. You need to make sure you have the right end on its designated terminal. Bosch Thermotechnology Ltd, Registered Office Address- Cotswold Way, Warndon, Worcester, WR4 9SW Company registration number in England 1993294. You need to find the hot water cylinder Opening this valve while monitoring the pressure on the boiler will add extra water to your hot water tank. How do you Repressurise a boiler without a filling loop? Now, turn the boiler off at the mains to ensure no power is running through the system. If it is not, water will continue to enter the boiler and drip down. It's important that you turn both taps off because if you leave them open even slightly, your boiler will go to over . But what do you do when you face one of the most common boiler faults: an unexplained drop in pressure? Fit the end with the stop valve near the main lines. In some cases, you may find that your filling loop issues actually lie with bigger issues for your boiler that need to be fixed. Watch the Pressure Gauge. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/b\/bf\/Repressurize-a-Boiler-Step-1.jpg\/v4-460px-Repressurize-a-Boiler-Step-1.jpg","bigUrl":"\/images\/thumb\/b\/bf\/Repressurize-a-Boiler-Step-1.jpg\/aid9295602-v4-728px-Repressurize-a-Boiler-Step-1.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"
