Looking at possibly getting a hydrovac system-input needed from owners

[Bruce L]

Our old sihi pump(19 years old),I believe is getting outdated and needs some work,new packing,seals etc,so I am considering moving it to the new smaller bush we just set up,and installing a hydrovac system in the main bush where we also have to use a separate pump to pump the sap up to the sugarhouse.Hydrovac looks like the way to go?,but would like input from owners or reccommendations.
Thanks.Bruce
