Jeanneau hot water tank pressure relieve valve

[Sailfree]

After buying a service kit for water pressure pump find its a leak via hot water tank pressure relief valve leaking.


Sure someone out there has had to replace this before can you point me to a source please. Boat is Jeanneau 43DS and only marking on fitting is TP 152 -1/2.

The TP152 is a Honeywell product, a combined temperature and pressure relief valve, with a 1/2" BSP screw thread. You should be able to get a replacement from any decent plumber's merchants. Most calorifiers only have a pressure relief valve, which would be a bit cheaper.

Screw fix for a similar T & P relief valve , (but with a 15mm outlet)

Also from Screwfix a simple pressure relief valve for less money ( 1/2" x 1/2")

If you do not have an electric immersion heater the pressure only valve is probably adequate

Thanks sounds right!

Apparently the valves come with various present relief pressures 2.5bar, 4.0 bar, 7.0 bar and 9.0bar.

Any idea what pressure a boat water system is?

Depends on your fresh water pump, you can find its cut-off pressure in the specs. 4 bar would cope with most pumps.
