Frequently Asked Questions

Q. "My Crane toilet model number shows up as an American Standard/Universal Rundle toilet when I search the Internet. Are you sure these are the right parts? Most of them say 'will fit'..."
A. Crane Plumbing has a very complex history, and it's very possible that your toilet was in fact manufactured by either American Standard or Universal Rundle, depending on when it was made. When looking for parts for a Crane or Universal Rundle toilet, we always recommend trying to find a date stamp that can tell you when your toilet was manufactured. In the 1990's, Crane Plumbing purchased Universal-Rundle Corp. and continued to manufacture many of their toilet models under the URC label, but the internal components (i.e., flush valves, flappers, trip levers, etc.) of many were notably different. In 2008, Crane was acquired by American Standard - who then continued to manufacture select Crane toilet models, but chose not to continue certain lines or provide parts/support for many of the older Crane/URC models.

Because Crane has been under American Standard Brands for some time now, OEM parts are often difficult to find. Many of the parts we offer for Crane toilets are considered "will fit" - a part that is not made by the original manufacturer, but will fit and function like the original part. While we have done our best to find you these "will fit" replacement parts, please be aware that they may not be appropriate for every situation or for every toilet with this same model number. This is simply a convenience we offer to our customers to aid them in finding repair parts for their Crane toilets. We strongly encourage you to compare the pictures and dimensions provided with your existing parts prior to purchasing, in order to ensure a good match and proper function. Please note that we cannot accept returns for toilet seats or for modified (cut, bent, etc.) parts, and any returns are subject to our returns policy.

Q. "When I search for a Crane model number, more than one toilet series comes up - how do I know which one to choose?"
A. When searching for replacement parts for your toilet, it is most important to find the TANK number to ensure the parts are a good match. Crane tended to take a "mix & match" approach to their toilet models, and so you will often see the same tank used on a variety of bowl styles. We include pictures of various toilet styles on our site so that those who cannot find or read the tank number in their toilet can still find parts.

If you already know your tank number, feel free to choose whichever series you feel looks most similar to your toilet and use the parts specified for that TANK number. Because of Crane's unique "mix & match" system, as long as your tank number matches, you should be good to go even if the bowl doesn't look exactly the same. As always, though, we encourage you to compare any type of "will fit" toilet part with your existing parts prior to purchasing to ensure you're getting the correct item.
