Hi,

I have a large tree in the wetlands behind my house where my sump pump water
gets drained to, Roots from the tree get in and clog the pipe and it is an
annual ritual to clear it using powered snake. I saw a root killer in home
depot which is not safe for sump pump parts and so needs to be applied
where the the waters gets drained. Is that a good solution? How effective
is it? Is there a root killer which is safe for the sump pump and so can be
applied into the sump.

Any advice is appreciated,

TIA

The last root killer I saw was just a couple pounds of copper sulfate
in a box.
If it's still available you might just be able to pour it into the
pumps discharge pipe and temporarily direct the sump pump out via a
hose so that it gets a day or two to work without being diluted. The
downside is it is not gonna be very good for the wetlands. It really
sounds like you have to re-engineer your discharge piping to do things
right.
