When to rebed thru-hull/seacocks

[Pavel24]

Hello, i am wondering when(how often) the thru-hull/seacocks need to be rebedet ?

My boat is on the hard , but the seacocks and tru-hulls look to be in good condition with solid backing plates. I put the rebeding on to do list but now i am wondering if i should.

Only when you replace them or they are leaking around the base (this shouldn't happen unless it was ignored or left from the initial install or major damage such as a collision). Outside that there should be no reason to re-bed thru hulls.

with mixed information online, i will check them all and service the seaocks but will leave the rebeding
