<br>
We have a tiny house project, and need to supply the pressure pump. My go to pump has been the Grundfos MQ series of constant pressure pumps.  They have no start up surge, and don't require an external pressure switch or pressure tank.  For small part time cabins, we've used the Shurflo or Aquatec diapraghm pumps.<br>
In this case, I fee that the Grundfos is overkill at 10 GPM, and that the RV pumps won't last very long in full time use.  Any other choices out there I should be looking at?<br>
I'm thinking 3 GPM max will be fine, but I would like something more reliable.  The pump would be preferred to be 120 vac, but I might consider a 24 vdc unit if it otherwise fits the bill.<br>
<br>
As always, thanks in advance for all your comments and suggestions.<br>
