Poe Leaks Through Nib

[bbs]

Hi All, is this likely to be a failed piston seal? It happens as soon as it's filled. The pen is new to me and as I flushed it to check it I also noticed that water is expelled via the nib hole as it fills.

 

Is this likely to be fairly easily remedied in Hamburg? It's a lovely pen but unusable at the moment .....

It should be a service level 1 flat rate price, but with WE pens that they might not have parts for that's not 100% certain. They would probably need to see it. I would hope that all internal piston parts, feed and feeder case should be covered under a service level 1 flat rate price.

 

I would advise you to ask someone I know at a boutique, but he's not there this week.

 

I can't visualise how water is expelled via the nib hole as it fills. Once it's filled with water, does water just drip out of the nib all of the time?

Thanks Chrissy, I can't get to New Bond St till next week anyway!

 

It didn't seem to drip water when filled as I was flushing it, but full of ink .... Well, disaster! Just glad I hadn't moved far from the sink.

 

Filling it while flushing, as it approached being 'full', water was expelled from the breather hole. Can't quite understand how it was happening either other than that the piston isn't working as it should.

I have no idea what you are meaning as well, but I don't think it would be the piston. When the piston is full retracted as when the pen is full it would not be putting pressure on the water/ink to make it leak back out the nib. When the piston is an issue it means you would not get a full fill or ink/water would make it behind the piston and worse case it would make it's way down to the filling knob.

 

It seems like your issue is in the nib or feed.

it makes sense... when piston seal is working the only way for the ink to exit and air to enter the ink chamber is through the feed. as feed does not allow the air to enter freely the ink flow is controlled

 

when the piston seal is not working the air enters through the back of the pen in an uncontrolled manner and the ink exits both through the nib and the feed.

Have you ever removed a piston from a Montblanc 146 FP? If you have a piston tool, it might be worth having a look at doing that.

Thanks again. No, don't have a piston tool and with my level of mechanical competence I'm not sure it would be a good idea to get one! I wouldn't like this pen to be my test run either ...

Send it in, have it repaired. As an owner of this model I can confirm it is worth holding on to and having in working order. It's definitely a keeper.
