Default need help on re-doing bulk head as it is leaking

Hi all,
siliconed my return and overflow bulkhead myself one year ago. Bullkhead are the one from haicheong with o-ring. Realised leaking (slow drip) from the base of one of the return piping.

did not realised that i siliconed the bulkhead wrongly till i read from another forum. basically i put silicon all over the bulkhead and the o-ring. anyway. it is bery diff to remove the bulkhead as i can only accessed to one side of the overflow even though my overflow is about 1ft by 1ft (i think).

So, can i remove the silicon of the bulkhead at the underside of the overflow and re-apply another layer of new silicon on it or do i really have to redo the whole thing. Of course will drain the ater from the over flow first lah.

thanks in advance.

Need to empty your overflow first.
Dry it and clear off all old silicon.
Then apply a new thin layer of silicon around the
bulkhead.
Wait for 24 hours and try leak test.
If pass leak test then ready to use.
If not have to start all over again.
Remember do not add silicon over
your old silicon.
This is not help you to solve the leak issue

Regards

Hi Sherman,
i was thinking of doing that just that i might have difficulty removing the silicon bcos of the spacing issue. in this case might as well be redoing the other return and durso at the same time. Thanks.
