Smart meter people said pressure loss and did not know if it was from pipe in floor or it could be fire value. Can these pipes be left in floor or will they have to be rerouted?
Check the meter if there is a different gas route to the fire. If so it could be cut of there. Or you might have to the room it is in floor and cut of from there
Post your job & get responses from local tradespeople. Read reviews before you decide to hire.
Hi, the gas pipe must not to buried in the concrete and have to be ventilated.
Get professional in and they will acess and advise
First of all the fire has an isolation tap, as should all gas appliances which could have been turned off and then the house retested. Having done that if there is still a pressure droip detected then the only possible cause is then the installation pipework.
If this pipework is in the floor, then ideally you would need to cap the pipework off before it enters the floor and rerun new pipework to feed you gas appliances
