New Symbol

Not sure if this is in the right section so please move if incorrect.

At present I'm looking at buying a new Symbol but I've read a lot of negatives regarding the internal Whale submersible pump fitted in the water tank.

Is it as bad as painted or just because more people tend to post on a forum when they have problems?

I suppose what I'm looking for are comments from current owners who've had no problems to give a bit of balance.

This is the main thing that's putting me off from buying.

If that is all that is putting you off then I wouldn’t worry at all. Mine has been fine since I bought my van over 4 years ago and even if it failed, upgrading to a Shurflo is a fairly straightforward job.
If it is a brand new van you are considering then it will also be covered by warranty.
Also, might be worth an introduction in the relevant section 

The same for me. The van is 7 years old this year and the submersible has not been a problem so far.
