My other post is pages back so I'm reposting this topic.
I have a sag in my drain line under the toilet. I currently have 4 gpf going into the line so I think that by going to a 1.6 gpf model it won't displace the water as well and will flush even slower.
Also, the water going through the drain line is what clears it. If I put less water through it (1.6 gpf), won't that cause solids to accumulate and worsen the problem?
I already clear the line with a water hose periodically but don't want to have to do it MORE often.
