So I have heard that you guys are great for service and price so here I am with my inquiry. I have a Kent marine maxxima RO/DI HI-S 35gpd system and would like a full replacement kit and flush kit for this system? Looking for price along with shipping rates please.

Assuming you are on city water without chloramines, without any particular issue with heavy sediment loads, and that you need a new membrane, and that you already have a refillable DI cartridge:
BFS-378 Filter Kit - Premium RODI - $27.48
BFS-52 75 gpd Filmtec RO membrane - $39.99
BFS-217 Capillary flow restrictor, pre-trimmed for 75 gpd - $4.00
BFS-81 Standard flush kit - $9.79

That should be all you need!

If you haven't done it in the last year, it would be a good idea to sanitize the system when you make this filter change.

Our sediment filters are true depth filters, in that they have four layers of graded density which results in a much higher capacity than typical sediment filters.

Our 0.5 micron carbon blocks that come in the kit above have a chlorine capacity of 20,000 gallons.

We recommend against reversing the flow direction through the membrane.

thanks for the great info but I do have one question. What is the reason to upgrade the restrictor to a 75 gpd vs. the current 35 gpd or even 50 gpd. I am using well water for my system which is a bit hard with sediment.

You'd jump up to a faster membrane like a 75 gpd if you want water more quickly than you get it now. The flow restrictor needs to be matched to the capacity of the membrane so that you maintain an approximate waste to purified water ratio of about 4 to 1.

Russ,

Thanks for all of the support with my order. The guys here in reef central were right. You guys are good and very helpful. Can't wait to receive my shipment.

Russ,

Finally got the stuff today that I ordered from you and added the pressure gauge. Looks like I am running between 40-50 psi on brand new filters. My TDS measurement before filtration was 139 and 1 following filtration. Would love to hear your thoughts.

What is the tds reading of your RO water. You provided 2 of the 3 measurements that are important to check:
Tap: 139 ppm
RO: ??
DI: 1

40 to 50 psi is ok. Would be better if it were higher.

I will work on the RO TDS measurement today. How can I get the pressure higher? Can I increase the pressure slightly in the cold water tank on the house. It's currently at 50 psi. It's been at 60 psi before.

The most common way to raise the pressue is with what's called a "booster pump." We carry these and all the add ons for them you might want.

those are a bit out of my price range at this time. Can I just run it like it is for now until I can afford one?

Sure. Pressure between 40 and 60 psi isn't a situation screaming for a booster pump.
