Two semi-detatched houses. A shared downpipe. One house has the original fitting round guttering, the other has replacement square guttering. The "professional" who installed the square guttering simply laid the end into the existing round outlet, packed some (what looks like) bathroom sealant around it. He then saddled up and rode off into the sunset.
[ Time passes, House gets sold. New people don't know who did the guttering. The seal degrades tot he point where it is completely useless. ]Now, I know you can get round to square adapters, that will connect a length of round gutter to a square length. However, I've never seen a downpipe outlet with one square side and one round one. So the question is: Can anyone point me in the direction of one?
Plan "B" would be to cut back a short length of the square gutter, install some round stuff coming out of the outlet and then put an adapter between the two types. However, we'd prefer a "proper" fix, rather than this sort of makeshift arrangement,
