Can you run a Gas Pipe Externally
Anonymous user 15 May 2019 - 12.28 PM
Hello All, I have discovered a Plastic Gas Pipe under the floorboards while renovating my Bathroom. I have had a Gas Engineer confirm the Pipe is not suitable for Piping Gas and it requires changing immediately. Although the Pipes running from my Gas Meter into my Flat and connected to the Boiler are both suitable for piping Gas, the unsuitable Pipe has been used to connect both ends in the middle. As the Pipe extends a long way under the Floorboards, I am unsure of where the Plastic Pipe requiring replacing starts and finishes. The Gas Engineer has therefore suggested, cutting off the flow into my flat from its current point and installing new pipes which will flow around the side of the Property from the Gas Metre and into the Rear of the Property. My Freeholder claims this is unsafe though but I have conducted some research of it appears pretty common on most properties. Can anyone please point me in the direction of the legislation/regulation which permits Gas Pipes to be safely run externally at the Property? Thanks in advance.

There is no problem with running a gas pipe externally its a perfectly acceptable practice. However you may require the freeholders consent to do this in any case. Also if you have had a gas safe registered engineer round he/she should have declared your gas Pipework as immediately dangerous and with your consent disconnected the supply at the meter and issued a warning notice and do not use label, until remedial work had been carried out Plastic pipe is not suitable or allowed to be used for gas pipe work in the property and is also notifiable under RIDDOR as an illegal gas fitting to the HSE.

The gas pipe can be run from outside of the property but must fitting by Gas safe registered engineer. Pipe work runs internally or externally must be protected from corrosion. Use standoff pipe clips not nail clips. Pipe work run in a wall. Run in a vertical duct or pipe chase be secure and keep joint minimum. 450mm minimum depth required if pipe work buried below open ground 40mm if below concrete slab with pedestrian traffic. In multi-storey pipe run vertical ducts must be ventilated high and low level , fire stop and sleeve required,AECV and test point required in multi story building. Conduct tightness yes before and after the installation To run pipe from meter remove meter cap off and keep in safe and clean place use temporary earth bonding minimum 1.2 meter long between upstream and downstream. After completion installation install meter back remove temporary earth bonding do tightness test , no pressure drops allowed in new installation

No plastic pipe work allowed on a gas installation although you can find external pipe work below ground wrapped in a plastic / poly sleeving. Installation should be classed as Immediately Dangerous and left turned off and capped. Possibly Riddor reportable. An external pipe run is permissible when adequately supported and wrapped in corrosion protective material

The gas pipe installed around the outside of the property would be acceptable, but first check with the owner of the property. All gas work in domestic properties in the UK can only be carried out by A GasSafe registered Engineer, it's the LAW. This will ensure that the work is done properly and to the correct standard. GasSafe registered Engineers are qualified, trained and have lots of technical knowledge this will also make sure that the gas installed in your home, wether its for cooking in the kitchen, or running your central heating and hot water, keeps you warm in winter, and is SAFE.(The plastic pipework in the tenants' flat has been fitted by a person illegally and is dangerous, always use registered Engineers, to keep it Legal and Safe).
