Hi all. need to tie into existing septic for rv dump. House has 3 inch abs. My sanitary tee is 4 inch so it can go a short distance and turn up to a flip door style at ground level which was also 4 inch. So. If I use the 4inch to 3 inch bushings when tieing in the tee apx 4-5 feet before tank. Will that cause any clogging / flowing issues ?
