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.

    TRV Valve is leaking out of pin

    Rad is leaking from TRV valve, seems to be seeping out of where the pin comes up. I tried tightening up the nut below the pin, but that didn't help. I then looked online and saw that removing the nut and packing with some plumbers tape may help, but whenever I try to remove the nut a load of...

    Hi, I need some advice. I am trying to replace the manual radiator valves on a towelrail with a TRV: I ordered a Myson 2TRV15SN, and the tail seems to be identical with the current setup, however I am not sure who to attach the copper pipe at the bottom. This doesn't seem like a standard...

    Honeywell 10mm TRV compression inserts wanted

    I have Honeywell Valencia TRVs 10mm pipe size, I’m making mods to accommodate larger rads and it looks like the 10mm compression insert is special to Honeywell as all available inserts are 15mm to 10mm which do not fit as the compression nut has a 10mm hole, not a 15mm. Anyone know if you can...

    Honeywell TRV low temperature

    Hi. I have all the rads in the house controlled with wireless Honeywell TRVs. This was done by an installer about 2 yrs ago. The kitchen TRVs are not working properly.

    TRV controlled radiators passing by

    Is it me or do others have the same. I have out of 23 rads in the house maybe 6 that pass by even when on the frost setting with the room temp at 10 degC. It is as if they need a small solid washer or similar inserted into the trv head to make it act a tad before it would alone. The rads do not...

    Are there any "Recommended" Smart TRV Valves for large houses?

    Hi All, I thought I'd come to the experts and see if anyone is installing and/or recommending the use of any Smart TRV valves? Particularly in large(ish) solid wall houses. I live in a 1920's arts and crafts house - it's about 2000sqft, not massive, but it's approx 25% larger on the...
