Just because you have a bunded tank installed , this doesn’t mean you are safe from a environmental disaster , always get your service engineer to check the tank for its condition and its their job to make sure the oil storage tank feeding the appliance they are working on is up to current standards,,, simple checks like
can the fuel be isolated in a emergency ? has it rusted open, can the fire service easily turn a tap
have the the O-rings and filter replaced , a real must and all our responsibility’s as heating engineers
the picture shows a cheap bunded tank installed in Dorset is showing signs of leakage , the old saying ! you pay for what you get is the same in the Oil tank world ”
This tank was installed by a huge tank company ,who obviously like to keep their employees busy by installing rubbish , it only lasted 4 years , but the tank manufacturer has changed its trading name , so no warranty
good job we did a filter change !!!!
