Since your's is new, this probably isn't the problem but I'll throw it out anyway. When we first purchased our pre-owned Scamp
19 several years ago, the toilet would flow very little water into the bowl. A closer review showed almost all the holes under the rim were clogged with a hard white calcium-like substance. I used an ice pick and clothes hanger to ream these out and its worked fine since. When was the last time your's worked properly?
