trv

TRV Tuna (801) was one of three Torpedo Recovery Vessels operated by the Royal Australian Navy (RAN) and Defence Maritime Services (DMS). Ordered in 1969, the vessel, originally identified as TRV 253, was completed in 1970 and assigned to the torpedo firing range at Jervis Bay. The ship received a name and the pennant number "TRV 801" in 1983. In 1988, the three vessels were sold to DMS. Tuna was assigned to the naval base at HMAS Creswell in Jervis Bay. Tuna was active in DMS service as of 2007.

    How to fix leaking trv

    Hi, Just moved in to a house and the radiator is leaking where the trv meets the feeding copper pipe. I’ve drained the system and had the trv off, it looks like when they’ve changed them they’ve made a small cut on the pipe under the olive. I can only guess this is what’s causing the dripping...
