RUN A WATER TEST

TO ENSURE WATER RUNS

TO DOWNSPOUT

TROUGH WILL PITCH 1/4"

PER 1' OR MORE

NOTE:

In extreme temperature swings, trough material

will expand and contract. Some wrinkling is acceptable but

should not impede the ﬂow of water.

To test for correct slope, pour a cup of water on

trough at ledger board ensuring water runs to

the downspout. (4G)

Follow above step for the remaining troughs.
