none of the pipes are/is damaged

One of the textbooks I currently teach states that though none should be followed by a verb in the singular form, many native speakers used the plural form. So I tell this to students and they´re more than happy to know that whatever form they put will be correct!

Good plan Avalon, but be careful to tell them that this does not hold when 'none' refers to a noncount noun, such as water.

None of the water has leaked out of the pool.

Oh yes, you´re right there...I don´t remember mentioning this, but I guess( not good enough to guess, I know) that they´d notice that it´d be wrong to say none of the water have leaked, cause it´s uncountable in our native language too, and chances are that they´d translate from our native language correctly...but thanks for the reminder, nonetheless!
