Ask Dr. HOG
In the spirit of brainstorming and problem solving we will be sharing some of the queries that come to us about installed HOGs or planned HOG installations. Our first is from Frank Katz in New Mexico who has two HOGs installed on their sides, and buried at the back of a raised garden bed.
ISSUE: HELP! Heavy rain is causing my filter to block and my garden may wash away in the next big storm!
Frank installed his HOGs in summer 2012 to water his Santa Fe garden. The HOGs form the back of the raised garden, and a retaining wall at the front completes the installation. The water in the HOGs can go two ways: either via a spigot to a hose on the porch for watering potted plants, or via a drip system to the front garden. Ingeniously, Frank is using an RV pump to circulate the HOG-held water.
SOLUTION: Frank plans on installing a larger filter. And he’s right: a larger filter would mitigate the heavy storm water flow. A large vortex filter, which uses cyclonic separation rather than a physical mesh to filter roof water is ideally suited to the heavy rainfall and hail of the Southwest. (Watch a video of a vortex filter at work here.) It is also important, with only 100 gallons of water storage, that the overflow from the HOGs is plumbed using larger diameter pipe (the same diameter as the downspout is best) above the level of the HOGs and the vents, and is routed away from the raised garden.
Backed up debris filter? No water pressure? An unorthodox install that works like a dream? If you have questions or solutions to share, talk to Dr. HOG!
