Hmm - didn't know they did that...

Their AAVs are good - as they only require to be mounted 200mm above the
highest junction (eg the tee below them) rather than above all local
flood lines, which could mean the basin. In practice this means you can
have them just a bit above the bog rim and box them in easily.

Not too noisy when they operate either.
