 Trustindex verifies that the original source of the review is Google. I called Chad as we had a Geberit toilet that wouldn't stop flushing He sent Danny over the next day. Danny was brilliant and sorted it out with some new parts in next to no time. Previously the toilet had been doing this and 2 other plumbers had failed to fix it. Thank you Chad and Danny, we will definitely be using CK Plumbers in the future.
