Planning gutter installation to reduce basement moisture.Live in a high snowfall area (shingle roof so snow won't slide taking gutters with it)Having trouble deciding which way to discharge gutters.I can either discharge towards driveway or towards side yard.(or both, but the length of just over 30' makes that seem unnecessary)Side yard: due to snow blockage I'm concerned that in early spring the downspout extension will collect the meltwater and then freeze at night causing water to back up the gutter and possibly burst the downspout.Driveway side: The driveway is kept clear of snow, so the downspout extension won't be buried by snow, but adding water to the driveway seems like a bad idea since it does sometimes ice over already.Would appreciate Anon's insights.
>>2996515collection system.
>>2996515gutter should typically drain out both sides like your arrows show, but the gutter in rear of house could be directed down hill to instead of sideways. The front gutter could be piped a foot underground to daylight in the same area in rear and shouldn't freeze. And if it does downspouts aren't expensive
>>2996515side yard discharge use the big gutters, 6 inch, and downspouts 4x5if you're concerned about freezing invest in some open top extenders or just use gutter pieces in the winter/spring thaw
>>2996548there's an idea... if discharging to side yard I could install diverters on downspout and switch them to divert in winter. Even If I'm not collecting in a barrel or whatever, a foot or two of tube would drip water away from house. Since it's above the snow and exposed to warm daytime thaw temperatures it shouldn't dam up.
>>2996550>the gutter in rear of house could be directed down hill to instead of sidewaysThe slope away from house to side yard is also decent
>>2996604don't have your extensions laying flat on the ground like in that picture. That has to be the dumbest thing I've ever seen people do, mount the elbow at least a foot off the ground for good slope
>>2996646>mount the elbow at least a foot off the ground for good slopeI think too steep is not good either, same as with sewer pipes:>too little slope and waste sits in the pipe creating clogs and odors; too much slope and liquid outruns solids, leaving waste stranded to dry and block the pipe.>https://plumbercalc.com/how-to/how-to-calculate-drainage-slope
>>2996773rain is/can be hundred of gallons flowing through the pipe, when you poop it's 2.5 gallons
>>2996773also your extension should be a 10ft piece, resting on one of those little T things to keep it off the grass
Is the moisture in the basedment from the snow melting adjacent the house?
>>2997561No, it's mainly a problem in summer after heavy downpours.
>>2997676That reads like you need to raise the grade near the front of the house to shed water to the sides as it comes down the hill.
>>2997688Grade is decently sloped away from house at the front for several feet. No ponding at foundation wall. Also the dampness is similar at the rear where it slopes away continuously. It seems like with the heavy summer rains the ground gets saturated and then it dries inward towards the basement because the geniuses around here don't bother waterproofing foundations.or putting poly sheets under slabs.
