I just installed a new water pump that was supplied by Shurflo at the GNR last week. All I can say is, WOW! The new pump is a 4008 RV By-Pass pump, and is standard in all new 2012 Winnebago's.
The new design is a 4 chamber design than minimizes pump noise and eliminates surging, even at minimal water flow. I had been using a standard 2.8 GPM pump with an accumulator tank to try to minimize the surging at low pressure. But the pump still sounded like a diesel exhaust brake coming on each time the faucet was opened and was fairly audible.
The new pump is 90% quieter, and delivers on it's promise of non surging. I don't think that this pump is on the retail market yet, but it is well worth it when it finally is. The motor is from an industrial pump so it is more robust and about 20% larger than the 2.8 model.
It is a big step forward in RV pump design, and much nicer to have on board. Now the only problem I have is that I have a nearly new 2.8 gpm pump and accumulator tank I don't need..............
