Waste tank inspection port

[Brett Caldwell]

I have a Bavaria Vision 44 2010. I can't remove the easy ta l inspection port.. assuming it unscrews.

Any advice?

They seize in place due to them not being removed very often.
Tap in an anti clockwise direction with a block of wood and hammer/mallet.
Don't go ham!! 
Hope that helps.

Sincere thanks for the advice..I'll let you know how I go.

I made up a tool based on a large water  Emersion heater tool with two shaped blocks of wood to fit the grooves. Found had to have leverage low down, tapping was not successful in my case.

Persevering with a rubber mallet and a piece of wood worked for me. A bit of a pig. I cleaned and then greased the threads with a silicon based grease  prior to reinstalling which is great for the next time.
