Gas pipework testing is an essential step that needs to be done before a new installation of pipes can be used. Gas tightness testing is a way to ensure that gas pipework is tightly secure and no gas is leaking through. If an installation is successful and the pipework has been tested to confirm that it is gas tight, the mains gas supply will then be safe to access through your home. Existing pipework can also be tested annually to make sure that it is still gas tight. The gas pipes running through your property should be tested to make certain that there are no health and safety risks being created by loose pipes.
Importance Of Gas Tight Pipework
The tightness testing process is protocol for plumbers and gas fitters. Gas testing should be done by a Gas Safe registered engineer and you should ask for a Gas Safe ID card before allowing any work to take place. Because gas leaks are toxic if it is inhaled, regulations state that it is better to be safe than sorry with who you choose for the job. If the smell of gas or the presence of gas is detected, the pipework would have failed the test and would need to be taken care of before any gas appliances can be used. Tightness testing reduces the risks of carbon monoxide poisoning and fires or explosions.
Before the pipework is installed, repaired or extended, it needs to be purged. Purging gas pipework is the process of removing any contained gas within the pipes before decommissioning the structure. This prevents any gas from escaping and contaminating the air in and around your home. This must be done before any work is carried out because the risk of leaking gas is hazardous to our health. It also increases the risk of fires or explosions if you choose to skip the purging process.
The Gas Pipework Purging Process
Once the Gas Safe registered engineer has taken the nessesarry precautions to ensure that the pipes are ready to be purged, the purging equipment needs to be set up correctly. This means that the ratios need to be calculated to allow safe gas pipe work to take place. The first requirement for purging is to provide entry and exit points for the gas to enter and escape the pipe. The purge gas is then allowed to flow through the entrance and the through pipe slowly to displace all the oxygen inside the pipe and push the air out through the exit point.
