IF they will agree. They MAY insist that to drill the hole, you have to get the whole shebang from them.

Yeah.... good point. You can almost buy a whole-house filtration system for 900 bucks. I might just look at doing that if I were the OP and skip the reverse osmosis system.

I've done it myself twice, including drilling a granite countertop. I even used carefully shaped copper tubing instead of the plastic tubing. I thought the hole would be more daunting than it really was, but was just a matter of having the right gadget and working carefully.

I admit that I'm a pretty accomplished (ahem) DIYer, but it's not extreme plumbing science.

A plumber will want more than $100, but it's not more than a two-hour job.

Tools you will need:

Drill or grinder. No variable speed grinder, buy this

5/8-11 thread to 3/8" shank adapter

Contain water during drill - you could use plumbers putty to make a ring

Water Containment Suction Ring for Wet Core Drilling

Drill bit

https://www.rocketsupply.net/arix-s43-stone-core-bit/ - notice it has diamonds on the barrel to prevent binding.

How to do it.

A plumber should be able to install it in under 30 minutes. I installed mine myself and it did not take me more than 45 minutes. Installing this reverse osmosis system is very easy. I suggest you do it yourself and save some money.

Unwrap the pre-filter cartridges and install them in white housing sumps. There is no orientation for pre-filter cartridges.
Tighten sumps with hand. Membrane should go in membrane housing.

All tubings are color coded.

White-Inlet
Black-Drain
Yellow-Tank
Blue-Faucet

A small 1/4" hole should be drilled in to your drain pipe to fit the drain saddle.
Tank will initially take 1 hour to fill. Flush it completely and then you can use the filter.

Check TDS with a meter and make sure your water filter is working properly.

Even a whole house filtration system (unless it is a large ro) does not filter water this good.

I read through all the post but I still don't know what to do. We already have a hole drilled n the countertop plus extra faucet ( new construction )but I don't want to go with the company offering the under sink water service. I tested the water myself. 293 ppm and the hardness stripe showed 1.5 gpg/25ppm. It is in the soft range so I am not getting a water softener. Trying to find a good NSF certified 4/5 stage under the sink reverse osmosis water filtration system with or without mineralization ?? Top tier alkaline ph ? It is so complicated but I guess the minerals are important.

Which NSF certified reverse Osmosis could you recommend. Also....it must be easy to sanitize the tank every six months.
