Water pump

[freewill2008]

ShurFlow pumps have treated us well for many years, but their quality
seems to have gone down the drain (sorry .

In our Bird, we replaced the Jabsco with a 4.0 gallon Smart Sensor
(no accumulator tank) ShurFlow last year. It lasted less time than
it took to install the pump and remove the accumulator tank.
Shurflow replaced it with a 5.7.

The 5.7 quit first time out while my wife was in the shower.
ShurFlow doesn't know why it quit, but give them credit for no longer
claiming the Smart Sensor pumps are trouble free.

We were out of patience with Smart Sensor so ShurFlow sent along a
Pro Blaster 5+ GPM Extreme Series model - same pump at the 5.7 but
without Smart Sensor. This meant re-installing an accumulator tank
so I shoe-horned the big stainless ShurFlow tank under the sink.

We like this system better because the pump doesn't start every time
we take a few ounces of water from the faucet. Trouble is, the Pro
Blaster 5+ pump has a problem with the check valve at the inlet (the
one that keeps water from draining back into the fresh water supply
tank) so this one will apparently need to go back to ShurFlow also.

Customer Service at ShurFlow has been great, but unless you really
like working on your water system over and over, I'd hafta say that
another brand would be worth considering.
