Should oil tanks be fitted with sludge cocks/valves?

No oil tank should be fitted with sludge cock or valves – UK regulation rules out this option for a multitude of reasons. The primary reason for this ruling is the added risk of spillage caused by the addition of any openings below the maximum level of oil and fuel tanks. Spillages and leaks can be highly detrimental to the environment surrounding a compromised tank, and very costly, so all necessary steps should be taken to avoid them.

When inspection or contaminant removal is required, this should be done through the inspection aperture, and by an OFTEC licenced technician.
