Finding Mansfield Toilet Repair Parts

Mansfield Plumbing has been making toilets for a long time and there’s a reason why they’re still around. From classic to modern designs and everything in between, all offering quality water-efficient performance, Mansfield toilets are definitely worth keeping. So what do you do when your high performing Mansfield toilet stops performing so well? You repair it, of course!

The first step in fixing your toilet is finding out what’s actually wrong with it – and luckily for you, we’ve got a handy guide to troubleshooting your toilet. Once you’ve figured out what’s wrong, you’ll need to find the right parts to fix the problem. Sometimes this is easy, sometimes it’s not so easy, but with a little investigative work and the help of your friends at PlumbingSupply.com®, hopefully it won’t be that difficult.

Start by trying to find your toilet model number. Grab a flashlight, CAREFULLY remove the tank lid (and place it somewhere safe and out of the way), and look around inside the tank for a model number. Older Mansfield toilet model numbers are typically three digits long – most of which start with a “1” for two-piece toilets or a “7” for one-piece toilets. Newer, more water-efficient toilets are generally four digits long and most begin with a “3”.

Usually the model number will be stamped onto the back wall or side of the toilet tank, along with “Mansfield” and a gpf (gallons per flush) rating. Don’t ignore the gpf rating! As toilet regulations and water-efficiency standards have changed over the years, Mansfield has taken a somewhat different approach than some other toilet manufacturers in remaining compliant with regulations. Rather than discontinuing and replacing many of their toilet designs, they have simply re-designed the way some of their existing models flush. Thus, you could have an Alto Series toilet with a 3.5gpf, 1.6gpf or 1.28gpf rating. They may look the same on the outside, but the way they work on the inside can be drastically different.

It’s important to note at this point, that any toilet that flushes well is holistically designed – meaning the amount of water, the flush mechanism, the way the water is delivered, the trapway, etc. (essentially the entire toilet) has been designed to work as a complete unit. What this means for you, as the owner and/or fixer of the toilet, is that in order for your Mansfield toilet to continue to flush well you need to make sure you’re getting the parts that are appropriate for your toilet’s gpf rating. You simply can’t put a flush valve that delivers 1.6gpf in a 3.5gpf toilet and expect it to work well.

So once you’ve found your toilet model number and your gpf rating, what’s next? Finding parts. We have a complete Mansfield toilet repair parts listing to help you out – just find your toilet model number, click on it, and see the parts you’ll need to fix your toilet. This listing can also be helpful if for some reason you can’t find your model number. Browse the available pictures of Mansfield toilets until you find the one that looks like what you have, then again click to see your parts.

One thing that may confuse some people at this point (especially those who have some previous experience with toilet repair), is that certain Mansfield parts are highly unique. Most notably, their flush valves. While some models may use the traditional flapper valve, others use a kind of canister-style valve. These valves use the same trip levers as their flapper-using counterparts, but the entire top of the valve is lifted up and the water flows in from all sides. Usually, if you have a toilet leak with this type of valve, you simply need to replace the seal around the valve opening. So if you look into your toilet and see something that looks like this – don’t panic!

This uniqueness of parts can actually be very helpful for those who can’t find a model number for their Mansfield toilet. If you look into your toilet and see one of the unique canister flush valves but no model number, your next step is to pull out a tape measure. Since the canister flush valves only come in three types – 3.5gpf, 1.6gpf, and dual flush (which are distinctly different from the other two) – it is fairly easy to determine which style you need, then measure your existing valve or the inside of your tank to figure out what height you need. It’s the same with trip levers, just measure to determine the length you need and then compare angles to make sure it will reach the flush valve or flapper chain.
