NEISH TOOLS Gas Pressure Test Nipples 1/8" Pack OF10

Product Information

If you’re considering additional radiators to your system now would be a great time to have them fitted. Some of your radiators might be old, inefficient or have leaks. They might be clogged up with sludge and not heating up properly due to internal corrosion. You might not have a radiator in your usable loft space and want one there or you might want to swap a single radiator for a double radiator. Whatever your needs, your installer should be able to help you. What size radiator do I need for my room? Gas pipe sizing is a must for all new combi boiler installations and will ensure you are paying for and installing the correct sized gas pipework for your current setup and your future needs. The calculations and formulas used, however, are sometimes complicated and some installers, unfortunately, take a ‘guess’ that 22mm pipework will be OK. A system to combi upgrade

Powerflushing – probably the biggest and most expensive con going and a subject that really bugs me. I’ve never come across a system that ever needed a power flush and I have never power flushed a system and I doubt I ever will. What is power flushing? Measuring mains water pressure alone will not provide a complete picture of whether a combi boiler will work well or not, the flow rate is very important as well.

3. The current mains water pressure of your system

It’s worth noting that some manufacturers will only start a warranty as long as the boiler is installed within 6 months of leaving their factory. 15. Notifying building control The test is now complete! The only part of the installation not tested for Gas tightness is the test nipple itself. To do this have some leak detection fluid/spray handy and apply it to the nipple and open the gas supply once more. If there are any leaks the spray would bubble up. Turn the gas supply off for a final time and wipe of any excess leak detection fluid. One thing to stress is you mustn’t be afraid to ask questions if you don’t understand anything or if you disagree with anything. It’s your home and you’re the one spending the money – so don’t be afraid to ask what the process is and why the engineer is recommending something. Smaller combi boilers deliver 9-11 litres per minute – it’s not great but it is adequate for a smaller property and a decent enough shower. The bigger models will deliver 16 litres or more of hot water – enough for a powerful shower, and be able to handle a larger number of radiators on the heating side. Return to the gauge, if there is no movement outside of the 20 - 21 Millibar range then it is gas tight. This is great and means there seems to be no leaks or issues. Step Six:

Any respectable company will not ask for money upfront for work they haven’t yet done. 3. The current mains water pressure of your system The ECO grant was introduced to help struggling families. The Energy Companies that agreed to help with this scheme are: How to work out how long a company has been Gas Safe registered by their number? Here are some rough estimates of how long a company has been registered, it’s hard to know exactly without asking: Estimated time registered with Gas Safe. Gas Safe ID numberThis scheme was set up to help you reduce your carbon footprint by improving the energy efficiency of your home. The scheme also offers other measures you might be eligible for including help with improving insulation. Therefore, the first thing the installer should do before attempting to give you a quote is to test your mains water pressure. Gas meter nipple spanner: Fits meter test nipples perfectly, making gas meter tightness testing easier.

Moving furniture is usually the responsibility of the homeowner or their representative. With your permission, and agreement to accept responsibility for damage or breakages, a responsible company will move furniture and other objects out the way. The position of the new flue terminal should also be considered. It must be at east 30cm away from any opening such a sa window or door. Boiler pluming As of 1st April 2005, any newly fitted gas-fired boiler in England or Wals must be a condensing boiler with a SEDBUK efficiency rating of either A or B. This means that if your current boiler (the one you are replacing) was installed before that, it won’t be a condensing boiler and might need some pipework alterations or upgrades. A combi to combi boiler swap Boiler manufacturers who offer long parts and labour guarantees will attend your boiler breakdown and if they suspect your system has not been chemically cleansed, they can refuse to honour the guarantee in accordance with their terms and conditions. As mentioned above, it’s a simple test to prove or disprove the presence of inhibitor.If you have an ensuite bathroom as well as a main bathroom you’ll sometimes be using the two showers at the same time. A few combi boilers can just about handle the hot water demand but only just about. It’s likely you’ll have a system or regular boiler in your property. There have been lots of articles on the dubious subject of power flushing, here’s a link to a few of them: Effortlessly attach or detach the PlumbShark from your keyring using the included carabiner. Its unique shark design and premium materials make it a thoughtful and stylish gift for any plumber, heating engineer or DIY enthusiast. There is also now a legal requirement to ensure installers only fit (in England) domestic gas boilers which have a minimum 92% ErP – roughly a third of boilers on the market fall short of this requirement. Bleed key: A stronger-than-average bleed key for easier bleeding of radiators, saving time and hassle.

To counteract this, your installer should dose your system with a corrosion inhibitor. This is usually done once towards the end of the installation. This stops the inside of your system corroding and, on older systems, negates the needs for a magnetic filter. Why do I need a magnetic filter on a combi boiler? Older gas-fired combi boilers (those installed pre-April 2005) were non-condensing and required only a 15mm copper gas supply pipe to make it run efficiently and safely. Newer, condensing boilers (installed after April 2005) usually require a 22mm copper gas supply pipe to make them run efficiently and safely – this is because they require gas at a higher pressure to be able to run at their most efficient. The layout of your current system and whether you want to keep it the same or upgrade to a different system will have a huge effect on the final cost of the work. Upgrading your system The heat exchanger, one of the main components of the boiler, can become clogged and restricted which could mean poor circulation, poor heat transference, a noisy boiler and a higher risk of a boiler breakdown. The pump can also get filled with debris affecting its performance. If you want to size up your own radiator then you’ll need this BTU calculator, and the height, width, and length of the room, as well as the type of glazing in the room. 12. Power flushing your system or flushing your systemNatWest, Royal Bank of Scotland (RBS) and Ulster Bank, which are all part of the NatWest Group, will now shut at least 172 of their bank branches in 2023 and 2024. Not all of the points will be relevant to your particular installation but this guide will at least give you an idea of what to expect from your new boiler installation and what to expect from an installer coming to your house. Flue gases from condensing boilers are cooler than non-condensing boilers so you’ll be able to see the discharge, particularly in colder weather. This is called pluming. Pluming can be a nuisance if crossing neighbour boundaries so a pluming kit is used to eradicate the issue.
