and valuable service is still our number one priority seven decades later.
Commercial
Industrial, commercial or institutional installations require inspections of the oil-burning equipment on a frequent basis by a TSSA certified technician. Generally, equipment refers to emergency generators, boilers and fire pumps which are regulated by the B139 Ontario Code.
If there will be a change of energy type to run this equipment, for example from fuel oil to natural gas, the existing storage tank will have to be removed by a TSSA certified firm.
Residential
Eventually, your fuel supplier and/or insurer will ask you to provide a written inspection report completed by a TSSA certified technician as to the integrity of your fuel storage tank and the health and safety of your oil-burning furnace or hot water tank.
Or you have decided to change your home heating from oil to another form of energy. This will require your existing fuel storage tank to be removed by a TSSA certified company.
You have a water well from where you draw your residential water. You turn on the tap and…OH NO! No water!

"The guys were great and super responsive on the phone and communicated very well with us on what we needed to do. I couldn't be happier with their work and I highly recommend them to anyone replacing an oil tank."

"I called Mannion Petroleum to remove the fuel oil tank when I converted to propane. The work was done quickly and professionally. I would certainly recommend this firm!"

"We first had Sean in to do an inspection of the property we ended up purchasing. He gave us sound advice and identified and corrected a potentially dangerous issue. The install was quick, clean and professional. If only all contractors were like Sean! Highly recommended."
