What water do you have access to? Many claim that spring water is the best to use to rinse the ro. Many, including myself, use well water because that is what we have available. If using well water and it is mineral heavy it is a good idea to use some type of filter. I use an RV water filter to remove as much iron as possible from my hard water...
I know some that use the first sap run to rinse with as well and then make permeate with the sap...

How much would you say it takes to rinse the membrane before you would start saving concentrate?

We used our well water because it was good. I think I ran about 250-300 gallons through our 250 gph RO. Most will probably recommend running atleast the capacity of your RO. More rinse is a good thing from what I am told.

Tapping since 1985 (four generations back to early to mid 1900s). 200-250 taps on buckets and then tubing in the mid 90s. 2013- 275 taps w/sap puller 25 gal. 2014-295 taps w/sap puller 55 ga. (re-tapped to vacuum theory) 2015-330 taps full vac. 65 gal, 2016-400 taps 105 gal, 2017-400 taps 95 gal. 2018-additional 800' mainline and maybe 400 new taps for a total near 800 taps. 2x6 Leader WSE (last year on it) supported by a 250 gph RO.
I was told by a membrane expert that you should rinse each 8" membranes with 600 gallons of water with low hardness and a low amount of iron and manganese. He told me "DO NOT RINSE WITH SAP!!" He said that if you rinse with sap, you will foul your membranes before you even get to use them. I tested the water in my deep well at my sugar house and at my house 3 miles away. The sugar house water was quite hard and had a lot of iron in it (of course) but my water at home is both low hardness and low in iron and manganese content. So I just haul 1,400 gallons (I have 2- 8" membranes) of my house water to the sugar house and rinse with that good water.

We rinsed ours in the fall with permeate that we saved. Our ro has 2- 8 incn membranes that were flushed with about 350 gal permeate, would that be enough, or should we run some well water thru still?

Sugarsand,
No offense ment here, but, why were you rinsing the membranes in the fall? If you only rinsed with 350 gal, that was not enough, IMO.
Did you have the membranes washed at Maple dealer or did you put preservative in the membranes?

I was told two things on rinsing RO before you fire up. One person told me just use 300 gallons of well water. The other told me to use my back up membranes and purify well water first and then rinse with that water. BTW... i have a lapierre turbo 250 and this will be the first year running it.
That depends upon the machine and size and # of membranes. Some use the rule of half the capacity of the machine so if it is a 600 GPH machine, 300 gal. is adequate. I'm personally of the mindset that more is better when it some to rinsing pre-season.... I also run a wash cycle and then rinse again as this is what is recommended for my machine.
Do you have a manual for your machine as it should specify the pre-season rinse and wash procedure that should be used. If it is a new machine, it should still be rinsed and washed...
To clarify, I don't recommend using sap to rinse, but was merely stating that some do this...

I have a 125 RO and fill one of my 275 gallon permeate tanks with well water for the initial rinse. I also use a new pre filter to catch anything larger than 5 microns.
