Pipe Installations, Repair & Rerouting

With over 40 years experience in the commercial HVAC services sector, we are able to deliver the highest level of quality for all your gas pipework needs. All of our pipework systems are tailor made for your property and the process is fully customisable in which we can add many additional components to help better your system e.g. UV water filters for a higher water quality, electrolytic scale inhibitors and catalytic limescale reducers to reduce limescale build up, gas booster pumps for higher gas pressure, solenoid valves for improved safety and circulation pumps to improve water pressure.  We always take pride in implementing cutting edge technology into our bespoke pipework systems such as trace heat cables that keep the water inside a pipe heated, reducing lead time on hot water and central heating and offering brilliant frost protection in a sub-zero environment. As a standard all of our pipework will be installed with full pipe lagging (insulation) as a basic measure of frost protection and heat retention.

All our gas pipework installations and repairs conform to the Gas Safety (Installation & Use) Regulations 1998 and are carried out by fully qualified Gas Safety registered commercial gas engineers, not just meeting but exceeding the regulatory standards set within the UK. The same goes for our water pipework installations and repairs, as these have and will always go through WRAS (The Water Regulations Approval Scheme). Our rigorous devotion to these regulations will allow you to sleep easy knowing that all of your pipework is to the highest standards available and installed with the utmost care and attention to detail when you have Flair Facilities at your side.

Steel barrel galvanised pipe and pipe threading

Many commercial properties including older properties continue to use steel barrel pipework as opposed to copper pipework, which is the most common type seen used within the heating and hot water sector.

Copper generally costs slightly more than steel pipe but is much more malleable than its steel counterpart and therefore much easier to work with. This explains why copper pipework is used much more often than steel barrel or galvanised pipe despite its increased price.

Steel barrel pipe threading and steel barrel joints require expensive equipment and specialist skills, because it is a much harder metal so requires a different set of equipment and expertise to install. Many younger plumbers and engineers simply do not have the knowledge to carry out this type of work as it is regarded as a rarity.

Steel barrel pipes and threading are also usually in imperial sizes but can be adapted to use with existing copper pipe work. This again is thought of as a specialty skill, but of course at Flair Facilities we undertake all pipework and implement the best solutions available on the market to make the improbable, possible whilst sticking to industry guidelines.

The reason steel galvanised pipe is advantageous over copper pipe is because it offers a longer lasting solution at a much lower material cost. Steel galvanised pipe in general lasts much longer because of the zinc galvanisation process. In laymen’s terms, forming the steel with zinc prevents corrosion as the iron inside the steel will not react with oxygen or water due to already being apart of the zinc. Normally the oxygen and water would oxidise the iron and cause the steel to rust, leading to pipe replacements at a much quicker rate. The galvanisation process also prevents other minerals from reacting with the pipes, stopping other forms of build up.

Pipe Installation FAQs

Your questions about pipework answered

Signs of an airlock inside a pipe are: no hot water coming from your outlets, hot water taps gurgling when turned on and cold spots in your radiators.

In general steel pipes are cheaper than copper pipes but are less malleable. As steel pipes are less malleable they are more durable, making them less prone to ruptures but they are also harder to install, leading to higher labour costs. Overall, you will most likely save money using steel pipes but if they are being used to transport hot or cold water they need to be galvanised to meet WRAS regulations. The benefit of copper pipes is that they are easier to install due to being more malleable and having a wider array of fittings available, steel pipes can only use a BSP fitting. Copper pipes are also less likely to corrode in comparison to steel pipes and they are more accessible, meaning they’re normally readily available in large amounts from suppliers. Steel pipes can be a bit more tricky to source, especially if you are doing a complete pipe refit and need steel pipes in large quantities.

The size pipes needed for a heating system depend on the system being used and the heating / hot water demands that need to be met, it also depends on what the pipes are transporting. The Gas Safe Register states that all gas pipes running from a meter to a combi boiler need to be a minimum of 22mm. If a higher flow rate of water in a system is needed then a larger pipe should be used, as it will allow more water to be transported at once. Another factor that affects pipe sizing is where in the system the pipework is; pipes running to a radiator are normally smaller (around 15mm), whereas other pipework is commonly done in 22mm piping. Pipes can range from 8mm to 35mm, each size having its own benefits and applications to specific circumstances. If the pipework transports gas then it is a legal requirement to have any work carried out by a qualified engineer a part of the Gas Safe Register, if the pipework is for hot or cold water we still recommend using a qualified engineer or plumber to ensure the right size pipe is used and the system works efficiently.

Pipework is generally replaced if there are frequent blockages and leaks occurring or if there is a substantial amount of corrosion, it can also be replaced if you need to reroute the pipes to suit new renovations made to a property. If you are uncertain on the health of your pipes you can have a water sample analysis performed, which will inform you of any particles in the water caused by blockages or corrosion, signalling whether they need to be replaced or not.

Legally plastic pipes can’t be used internally to transport gas, as they are classified as exposed and if damaged could have dangerous repercussions. Plastic pipes are allowed to transport cold and hot water but we recommend using steel or copper as they’re easily damaged and more prone to ruptures, in comparison to their more durable metal counterparts.

An automatic air vent or automatic bleeding valve is used to automatically release air trapped inside a heating system. They are attached to pipework and have the valve facing upwards, as the component uses a floatation mechanism to let air within a system out without letting any water escape. An auto air vent will usually be placed at a high point on a system to prevent any air locks from occurring within a system.
