Toilet just installed water keeps running

This question is from Wellworth Classic 2-piece 1.28 GPF Round Front Toilet with Class Five Flush Technology in White
Asked by
Bennington VT

July 1, 2016
I just purchased this toilet and had it installed by a professional plumber. The water comes on and keeps cycling to the point where we have to shut off the water after each use. The plumber came back and said that it is a defect in the toilet and that it should be returned. Plumber also said that it was a common problem with this toilet and it would cost more to try and fix which they could not guarantee rather than getting a new toilet. I do not see this problem mentioned here in questions or comments. Can you help me with this problem? Thank you.

Rated 4.5 out of 5 by 183 reviewers.
Rated 5.0 out of 5.0 by black toilet Everyone told me buying a black toilet was a bad idea But it looks great in our bathroom. Function is very good but why does a black one cost twice what a white one does? July 16, 2013
Rated 4.0 out of 5.0 by Fits right in with the decor completes the bathroom fitting in with the decor of the room December 9, 2015
Rated 5.0 out of 5.0 by Our new toilet is so BEAUTIFUL It's not only elegant looking, it's flush capability is wonderfully forceful. Now our toilet is not an eyesore but an accessorie. Thank you for this wonderful product June 18, 2013
Rated 4.0 out of 5.0 by Great looking toilet but missing some black paint on back This is a great looking, stylish toilet but missing some black paint on the back as pictured. Seat is a little lower to the ground than I would like too. Works great! September 17, 2013
Rated 5.0 out of 5.0 by Good tiolet Awesome size and good for small restrooms or half restrooms color black nice and fancy awesome flushing and saves water too way better then what i had before July 14, 2015
Rated 5.0 out of 5.0 by Exceptionally Pleased We are pleased with the purchase, the small additional expense for color is more than worth it; quality and attractive - Exceptional choice. July 21, 2015
Rated 5.0 out of 5.0 by does what a toilet needs to do Toilet looks great once installed and for the price you cant beat it. Had some trouble installing the toilet trying to fit it with the existing plumbing. Works like a charm. April 11, 2016
Rated 5.0 out of 5.0 by Its a toilet! This toilet replaced a much much older one we had. It flushes much more quickly and easily. It's definitely quieter, too. We had a plumber install it, so cannot comment on the ease of installation. The toilet comes packaged in two boxes- the tank separate from the bowl- so it was very easy to transport two of them in our car. July 13, 2016
