Does anyone have experience with a C-tube pump?  What are your thoughts compared to an S-tube and do you clean out the same?  Thanks for your time.

Very good pumping system, what kind of pump? big boom or?. Very easy to clean if you know how to do.

32 meter boom, Putz.

Very good system , easy to maintain, but if the concrete is a bit sharp then you will have more problems than with a s valve, From pumping the last bit of concrete to driving off site the quickest washout will be 20mins(clean) by sucking back. Be careful of build up in the deck pipe. You will get more meterage out of a c/trunk than out of an s valve.

What size pump unit have you got with it? the long 2100(h) with accumalator change over was always better than the 1400 and how old?

Thanks for the helpful info, I think I've decided not to buy that one.  I'm leary of it since I'm not familiar with a c-tube.  I appreciate the help.
