For the second time this season someone in our family (“I think it was me”, he said sheepishly) inadvertantly left the rain barrel valve open and drained the barrels dry. Over 200 gallons of precious rain water lost, again! It’s amazing how quickly we’ve come to rely on the rain water for our garden and how reluctant I am to use our public water supply. It is such a waste of resources and money.
I think from this point forward I’m going to take advantage of the valve system I have. If you look at the photo, you’ll see there are shutoff valves between the two barrels to the left. The next time the barrels are filled I will close off these valves so that the two barrels are isolated. That way, if we once again leave open the tap, we won’t lose more than half the water. I am also hatching an idea to build a second backup system for my lawn and emergencies.
ADDENDUM
Several hours after posting we were blessed with a torrential downpour and my rain barrels are once again full — nearly 200 gallons. It’s amazing how much water runs off a roof. I have now closed the stops to the last two barrels in the series as a precaution. I will open them only if the first two barrels run dry.




I am seething with jealousy. Believe it or not, here in Denver it’s actually ILLEGAL to trap and store rain water.
Yes, I had read that somewhere. Do you get most of your water from wells? Is groundwater so precious that it must be allowed to percolate down to the aquifer? I thought your water was from snow melt. I read that reusing grey water is also illegal. Very strange thinking indeed. Sounds like a reason to start a campaign to repeal the law.
Nice setup . I just added a Shurflow 115Vac ParkModel(RV) water pump with prefilter. Has a 45psi auto shut off and is very quiet. I am really impressed with how well this setup works. I have (9) 55 gallon barrels all with manifold setup on my property and have not had to use city water yet.It has become an addiction but when I water I feel good knowing its good for my plants and good for my wallet.Keep up the good work. If you would like to see my setup which also uses Gardinia fittings I can email you.Take care Issac ikestyles@yahoo.com
Issac, yes please send along photos of your setup. I can post them to the blog and share the knowledge.
