Here I am with another problem that is causing me some sleepless nights....
My boat (steel) is equiped with 6 drainage pipes (steel, 3 on each side) that lead from the deck
to just above the waterline.
The boat has been lying alongside a jetty that is being populated each weekend by literally up to 35.000 (!) "kids" excercising "battle-drinking".
For some reason they think my boat makes a better wastebasket than those provided by the city and throw (to smash) empty bottles (and bubble gum and anything else they want to discard) on the boat.
The boat has been neglected for some 3 years - and you would not believe the amount of glass of any size that I have removed from the deck
2.: Problem 1
Some of that glass, + bubble gum + "natural environmental dirt" + flakes of old varnish
have washed into these drainage pipes, clogging them up effectively.
The pipes - for some reason unknown to me - are only of approx 1" diameter (even so there would have been plenty of room for twice that size!).
I have tried poking through the blokage with some strong steel-rods: invane.
I have tried to wash it out with a hose from top or bottom: invane
I managed that the water
does "trickle out" again, but am far away from "free flow".
So I now baught a special tube-cleaner for my pressure washer and will try that out today. Wish me luck! .... If that does not work, I really am out of ideas.
3.: Problem 2
The pipes being steel
, having been sitting with water
standing in them for a while, it is no surprise that they have started rosting.
This not only makes for ugly brown streaks flowing down from the bottom hole, but obviously includes the danger
that eventually they will rost through, spilling water INTO the boat.
So I am also looking for a possibility / idea how to get a decent amount of rost converter into these pipes (after freeing them of the blockage) to stop the rosting ... and ... how to best follow this with some possibiity to apply protective paint
to all of the pipe's inside!
Problem is, that I can not access these pipes from the inside. There is lots of interior
built which I would have to rip out first (naturally: I do NOT want to go that road!)
I am also not sure if it would be possible to weld new pipes as replacement (twice the diameter) from the "outside" without setting the insulation
and furniture on fire (?!) ... But, even if that would be possible, it's not an option because for some reasons we will not be able to drydock
her until next spring. So I have to find a solution that lasts at least one year.
Am grateful for any and all tips and advice!
