About your watchman sonic product
The Watchman Oil Monitor acts as a level sensor to indicate how much home heating oil is left in your oil tank. The oil level sensor continually monitors the oil level and when it is below 10 per cent, the fuel dispensing pump symbol appears on the receiver as a reminder to order more oil.

Top FAQs for replacing your oil tank
Q. What should I understand before I buy a replacement oil tank?
Firstly, you should be aware there are two types of oil tanks available. A single skin tank is made up of just one tank wall, where as a bunded oil tanks consists of a “tank within a tank” design. Bunded tanks are proven to be more reliable than single skin tanks. If in the event the inner tank splits within a bunded tank, the outer tank offers that additional layer of protection. In addition, the risk of pollution can be minimised by installing a bunded oil tank.  Choosing between a single skin or bunded oil tank can be difficult, however in the event of an oil spill the clean-up costs can be considerable and may not be covered under your house insurance.

Oil tanks should always be installed by a trained technician or preferably a OFTEC approved installer.
