I took apart and cleaned my DE filter for the first time and had a question about draining the water from the filter. My filter sits on a concrete pad very close to the property line of my neighbor. When i removed the drain plug the water drained onto his property and flooded his flower bed killing some of his plantings there. Can anyone suggest a way that i can drain my filter and control where the water drains? The drain plug is about four inches above the concrete pad so it would be difficult to catch the water with a bucket due to low clearance and a tight space. Because of the orientation of the drain plug Its natural path is right into his flower bed. If i put the backwash valve in the backwash position would some of the water drain from that valve just from gravity with the pump off? I don't understand the plumbing of the filter very well so that may be a dumb question.
