    Plumbing advice- tap seat replacement

    The faucets in my place are rather old. I'm burning thru a washer in the bathroom every few months, and it doesn't seat very well at all. I've tried just about every brand and composition washer with the same outcome.
    I've reground the seat, using the valve seat grinding tool, but it appears the brass seat is well beyond saving (there is a crack or corroded section which allows water to leak past the washer, and chews it out in no time). The joys of hard water.
    Is it worth going the next step and drilling / tapping in a new valve seat, with one of the valve seat repair tools, or is it best to get a whole new tap body brazed in? Hoping to keep the standard faucets if possible.

    Over the years since we've bought this place, I've changed almost all of the taps to have ceramic inserts. In most cases, have kept the original taps / valves and just installed inserts. Kitchen and bathrooms though, I have replaced the entire taps with new ones with ceramic internals (old ones were pretty crappy looking, and we have renovated both bathrooms).

    I have found that, though initially expensive, the ceramics pay for themselves in the longer term. I think I have only had to replace one ceramic insert.

    The other good thing with ceramic inserts is that you don't have to turn the taps off "tight" which is usually what buggers conventional seats and washers. The inserts I have used only rotate through either half a turn (in the kitchen) or three quarters of a turn in the showers and outside from fully on to fully off. The action is very "light" and there is no force or pressure at all required to turn fully off.
    Cheers .........

    I think this is what I need.
    By the looks the ceramic 1/4 turn jobs eliminate the washer and seat altogether, as the sealing happens within the spindle?

    Pending sizing I think one of these should do the trick. Do the old rip it out and toddle off to bunnings trick

    I've tried teaching the Cook how to lightly turn taps off! Doesn't work... huge amount of force necessary to turn them on again and that's where the flattened washers come from. Grrr.
    My old mum used to be the same......must be a female thing where they have no sensitivity.

    No mechanical sympathy, i use the yellow poly washers and they hardly ever need replacing.

    Yep, no tap washer known to man can withstand being turned off by the females in my house more than a few times. Going to have to get me some of those ceramic gadgets.

    I wore the yellow poly ones out in about 6 months.
    Thought I'd get fancy and try the hydroseal ones with a brass mating face and an O ring that seals under hydraulic pressure from the water behind it, but it lasted 4 days. The valve seat is just too far gone.
    Missus has the strength of the devil, I swear...

    I also looked at those ceramic jobs at bunnings, about 20 clams a side, but I also need to get new tap handles to match the different spindle spline type (the joys of a 60 year old building). I need to pass this by the boss before I make a bloke's decision- "It works, it'll do... it doesn't need to match the curtains"
