    Hi, this is Laura with Kohler Co. I am happy to assist you with your question. We do not recommend installing a Wellworth tank on a Serif bowl as this has not been tested so we cannot guarantee compatibility. The same attachment hardware is used so while it may fit, we can't recommend it. Thank you for choosing KOHLER.

    I was very disappointed after having researched so many toilets! There are no instructions on how to adjust anything like tank fill, bowl fill or how to use the dual flush levers not ever having had one before. There is no power to the flush and though it does clean everything, I keep thinking there's going to be a back up one of these days though we've had it a month and so far so good. Unfortunately, I am comparing it to another new toilet we got at the same time, different brand with power flush. It is a single flush, but has a comfort height instead of the Wellworth standard height which is much better for shorter people. At any rate... it's an ok toilet, that's it, I would not recommend or buy again...

    Works as well as I had hoped! The boxes containing the components were mangled, but the contents appeared in good shape. Flushes like a dream and looks good.

    Very happy with our new toilet. We had the same toilet in our half bath for the past 2 years and were pleased with it. The handle does have a small green lever which we don't mind at all. I have another dual toilet with the handle on the top, I prefer the side handle.

    Response from Kohler Product ExpertJune 7, 2019
    Hi Prateek, this is Sarah with Kohler Co. I'm sorry to read that your Wellworth toilet is not flushing properly. We would suggest checking a few things within the tank. If the trip lever is not returning to the home position, you can first remove the trip lever box (on the inside the tank) and reinstall it to finger tight. Next, we suggest flushing out the fill valve. To view an instructional video explaining how this can be done, please follow this link: http://bcove.me/vl3k3edf. Please email our team at KohlerCustServ@kohler.com for additional assistance. We're here to help! -Sarah B. KOHLER Customer Service
