Some experts say that the most important part of a crawlspace sump pump system is the pump. That makes sense, right? You can't keep a crawlspace like the one under this Owensboro home dry unless you have a reliable, powerful pump. There's something else to consider when drying out your crawlspace--where is the water going that the pump is pushing out?
It's a common problem when trying to do it yourself, or when dealing with inexperienced installers--they often don't make the discharge line long enough. Part of the reason that they short-change homeowners on proper discharge line length is that their sump pump isn't powerful enough to force the water out far enough to keep the water from flowing back into the crawlspace.
Healthy Spaces crawlspace waterproofing experts recommend that a minimum of 10' of discharge line with proper grade be installed. That's a minimum and it's better to go further than that. It's also vital to make sure that you have an IceGuard where the discharge line exits the house, so the discharge line doesn't freeze.
