Standing rigging 20 years old

Why would I want to change a serviceable item ?

Think on this : Ships not only have large valves and seacocks .. but also many small ones ... they do not change every 5 years - in fact vast majority of them go the life of the vessel in far harsher conditions than your boats ...

5 years sounds a touch short, but when we had our boat surveyed last the surveyor - hardly a gorilla - managed to rip one of the seacocks off the through hull with his bare hands. Fortunately while on the hard.

They don't last forever. The boat is only 15.

There are seacocks and seacocks. Some last forever, some shouldn't be anywhere near a boat.

As another says - there are Seacocks and there are seacocks ..... I will not have plastic regardless of brand name.

I've only got one plastic one, and that's not corroded at least.

Problem with plastics is not corrosion ... its hardening and then cracking.

Indeed, they don't last forever either.

I certainly would not 'live' with plastics as I have with quality bronze fittings as my boat has for all its life since mid 70's.

I am only thinking to replace the bog outlet as the cone seized after winter and took care to free up again while still afloat.
But replace is actually not 100% decided as it will depend on strip down when lifted out. If its still as previous .... its a dismantle , clean, lubricate and refit.

Not just plastic, fibreglass. Any reason why the fibreglass skin fitting shouldn't last as long as the fibreglass hull that holds it?

Brass, on the other hand, shouldn't have been fitted in the first place. The 5 year reference comes from a poorly-worded paragraph in the RCD, which provided the "permission" for a range of builders (not just the obvious ones) to install brass.

If it's brass, or if you're in any doubt that it's brass, or even if the internal workings of the ball valve might be brass, it should go. If it's all DZR, or fibreglass, or indeed bronze, then I would be looking at 25 years (or more) not 5.
