Downspout Lines


HZG witness today one of the worst downspout line installations of all time. The homeowner wanted to blame the waterproofing for his wet basement. However, upon noticing water stains around the downspout leaders we popped the caps. Low and behold, standing water in the downspout line.


Upon digging the lines up and seeing the puddles of water around all the broken lines (standing water, freezing), we pointed out...the backwards pitched lines. It would matter if you had a powered pump discharging the water, it would roll right back.


Downspout lines should be pitch to drop a quarter of an inch every eight feet (or so). The only way to correct this situation (due to the run) is to raise the sump discharge above grade and have a portion of the line exposed...and then put a mulch bed over it...
