just read the tablet and make sure its ok for plastic and paint.... cause it might mess up your paint.... its not hair clogging it up like those tablets usualy disolve its just dirty... or maybe some tree debri..

 

I wouldn't use the tablet...

 

Yeh thats a good point.. didnt think of it like that..
Will try the air pressure next time my mate is about and i'll let y'all know how it went!

 

If you need to physically poke something thru to clear the blockage... Try some plastic weed-eater line. It's flexible for where the tubing curves & it won't poke thru the side of the rubber tube.

 

I would never have thought about that.. (the weed eater line)

anyway the air pressure is your best bet...

 

the weed eater line is a good idea BUT its not solid enough to do any good.....
you can use a coat hanger... just remember to keep spining it and dont just ram it thru the hole... poking thru the hose shouldnt be a problem BUT air pressure is the best route i think for most small clogs
