Step 7: Assemble the Valve

Install the bulkhead fitting by removing the nut and friction washer, then passing the fitting with the rubber gasket attached from the inside of the barrel through to the outside. Install the friction washer then thread on the nut. Finger tighten the fitting.

Note: The left-hand threads of the bulkhead fitting will provide counter-rotation when tightening the right-hand threaded valve assembly into the fitting.

Attach the nipple to the valve, applying Teflon tape to the male threads. Use slip-joint pliers to create a tight union.

Apply Teflon tape to the male threads and join the valve assembly to the bulkhead fitting. apply the pipe wrench to the bulkhead fitting washer and tighten the valve assembly. Tighten the valve assembly firmly and rotate the valve handle to the top. Then use the pipe wrench to tighten the bulkhead fitting.

It's easy to over-tighten this connection and deform and possibly weaken or damage the barrel, so wait until the barrel is filling with water to determine how much torque is needed to keep water from leaking through this joint. Adjust the tightness of this fitting to be just tight enough to keep water in when the barrel is full. Hold the valve in the desired position and turn the large nut with the pipe wrench. Remember, left-hand threads tighten the opposite direction! The nut on my fitting actually depicts the direction to rotate (counterclockwise) to tighten.
<p>To add extra storage you connect the over flow to the the new barrel right and the create an new over flow for that one you just attached it will also need its own exit to get water out?</p>
<p>Good idea!</p>
<p>I'm building my rain barrel with that same style barrel and I'm concerned about it being unstable due to the tapered base. Have you had any problems with that?</p><p>Thanks for the unstructable. I will copy many of your ideas.</p>
Glad you like it, I have 2 I've made and have had no problems at all. Remember, these barrels are designed to hold things like pickles and olives, so they hold liquids by design. The base is smaller than the overall diameter, but plenty stable. Keep it on a stable, level surface that can support the weight of 55 gallons of water and you should have no problems.<br><br>I have made one modification since this was posted. I have inverted the strainer on the lid, so it points up instead of down, This has eliminated clogging of the strainer almost completely. <br><br>Let me know how your barrel turns out!
nice. <br>can we used a 19 ltr tube also for the same method?
Great 'ible. Also, remember to check your local code on rain barrels. Previous city I lived in had a law that stated the rain barrel must be disconnected during winter months, and drained completely. Plus, rain barrels were not allowed to be visible from the street. (Since I lived on a corner, this was difficult.) The exception was detached garages - there was no ordinance covering these units, so they could be left in place year round.<br> <br> My question on the previous model you referenced with the flexible hose: did the water ever run fast enough to dribble over the lip of the top of the barrel? &nbsp;With the concern locally over West Nile, I'm wondering if the water will pool and puddle (even splashover) or if it all drains in.
Thanks for the comment. I haven't heard of local ordinances regarding rain barrels, so that's interesting information. I did mention removing rain barrels during winter months, to keep them from getting damaged by freezing weather. <br><br>What did you mean about detached garages and leaving them in place year round, I'm not sure what the &quot;they&quot; referred to in your statement. Is sounds like the garages could be left in place, which makes sense to me... ;^)<br><br>I have never had a problem with water overtopping the barrel, even during really heavy storms. It is important to clean the screen from time to time to keep it clear of debris, but with a 3&quot; opening there is plenty of room for the water to enter. Interesting point about mosquitoes; I do find that the top pools a little bit, so I drill 2-3 small weep holes through the top on the low side, to allow those pools to drain. <br><br>The screen on top keeps adult mosquitoes out of the barrel and prevent egg laying. It also keep adults in that happen to wash in as larvae and mature inside the barrel. The concern is exposed standing water for mosquitoes to reproduce, so no exposed pools means no habitat for larvae to mature.
