BWI Plumbing SR-1 5 Stage RO-DI unit

I have had the pleasure of procuring a new RO-DI unit for my fishies. This is all part of my quest for domination over the evil Hair Algae that has taken over my tank.

The SR-1 units all come plug and play. It took me just over a half an hour to get this hooked up. It was very simple.


1. Remove from box (VERY well packaged by the way): 5 minutes

2. Unwrap media (VERY important): 5 minutes

3. Main unit screwed to the wall above my set-tub in the basement. Make sure to use a level. : 10 minutes

4. Rinse out everything. You may not need to do this but I do it for everything I buy that goes in the tank. Often I use a vinegar/water solution.: 10 minutes

5. Screw in tanks. Comes with a handy tool to assist in this. Makes the job real easy.: 5 mins

6. Hook up water feed, waste drain and processed line: 10 minutes

7. Turn on water.

My output was dead on as expected with the first batch. After tossing out the first 5 gallons (to get rid of the residue from the filters that may have come through) the filters produced about 24 gallons in about 8 hours. that’s 3 gallons per hour or 72 gallons per day. A great first run for a 100 GPD unit. Most units will run short for a while until the membrane gets worked in.

After the test run above I took the advise of a friend and ran my water from the furnace’s humidifier feed line instead of from the sink. This required only that I buy a couple pieces of 1/4″ tube fittings for a T-junction and a on/off valve.

The process of hooking that up only took 10 minutes.

Overall I am very pleased with the product. If I had to make any criticism it would me to include some fittings and screws to hook it up.

I’ll include some pics of my unit and hookup. The image above is from the BWI website.

OH! Go here to view the entire line.

They also sport a good line of PVC fittings, tubes, bulkheads and Check out this bulkhead alternative.

Oh, and Join the Revolution!

    I thought it was for water filtration but it will work on aquariums as well, but it will take at least 2 months to change the filters?
