More ballcocks

“Seacocks are a semi consumable item, so you should plan to replace metal ones every five years.”
I do get fed up reading this twaddle, this in the latest YM.
I have no plans to get rid of my excellent 44 year old bronze seacocks!

There was a time when Yachting Monthly highlighted the scandal of substandard rubbish being put into new boats. If your information is correct now they collude with it.
Such is progress, but not much to be proud about there.

Like cars …..after sales and replacement where the money is

It's true-ish; brass, DZR or not, will degrade when exposed to salt water and need close inspection at haul-out, 10 years might be a more accurate 'book' life for DZR provided they're not subject to dodgy stray currents or defective anode protection. Bronze fittings should be inspected(as should all underwater fittings) but generally they should last the life of the vessel.

Plastic ones should last 1000 years, so long as they are kept in the dark...

I beg to differ. The DZR Blakes seacocks on our previous Sadler 29 (1984 vintage) were a) original to the boat and b) still fine when we sold her a few years ago. The exception to this was the heads outlet, which I replaced at around 30 yrs old, as the plug had got pitted (too deep to grind out) and wasn't sealing properly. I'm guessing this was due to nasties in the toilet outlet...
