How-To Make a PVC Pipe ReservoirFormer staff writer - June 24, 2004

Today, I'm going to help you keep a little bit of money in your wallet by showing you a step-by-step guide on how to build your very own reservoir for your water cooling system. Store bought reservoirs can cost $20, $30, or even up to $80 and they all serve the same purpose. They serve as a fill point for your water cooling system and an easy way to bleed the system. Building an entire water system is beyond the scope of this guide but we may update it later to include such information. Today, we're going to build a custom made reservoir for less than $8 bucks. Let's get started!
What You Need
I used 2� diameter PVC pipe purchased in a 6� length. I don�t have the exact cost but it was only a few dollars. As I have used pieces of this PVC pipe for several other projects, the cost is next to nothing. Cut out a 4 �� length of PVC pipe for the body of the reservoir. You can use any length you please.
Building the Reservoir
I dry-fitted the cap and screw adapter on either end of the PVC pipe to insure that all pieces would fit together. Next, I used a variable size drill bit to drill holes for the PVC female adapters. It is important to not make these holes too big or you will not get a water tight seal. I drilled the hole close to the size I needed and then tried fitting the female adapters and then drilling the holes slightly larger until the adapters fit snugly.
Next I dry-fitted the adapters to insure a tight fit. After doing that, I disassembled all the parts and cleaned them with PVC pipe cleaner making sure that the parts are as clean as possible. Now, follow the directions on the PVC cement and apply it to each piece and re-assemble. DO NOT try and use glue other than PVC cement. I have tried and I can vouch from experience that other glues will not work. PVC cement (available at your local hardware store) is designed to actually melt the pieces of PVC together creating a fully water tight seal.
Attach your tubing, fill with water, put the cap on, and you are all set. Here is the final Result:
As you can see the total cost was about $7.50 for all the parts and about 10 minutes of labor, not including the hour I allowed the glue to dry. Not only did this save me a substantial amount of money over a store bought reservoir, I have the sense of satisfaction of building something myself. Overall this was a very easy project well worth the time and effort.
