These tools helped make the replacement simple and quick. I have saved them for future use.

Beautiful 100% replacement. Easy to install. Took about 20 minutes start to finish. No problems!

We have/had Mansfield EcoFlush 2-stage flush toilets, one sprang a leak, the other is fine still. Time to replace the leaker. Research finally revealed that this was the best across-the-board replacement, Ordered the product, got here quite fast, all parts needed were included. I needed a Philips screwdriver, a flathead screwdriver, a crescent wrench, and a large monkey wrench to disassemble the old unit and install the replacement. Tools here at home. It took me 2.5 hours to do the entire job while my husband was at work. I took my time. A couple internet searches to find out how to take the old handle off from the outside first, and that I needed to remove the top tank from the bowl to make the job super easy to remove the old pressure tank and install the new. Again, I took my time and made sure I understood the instructions well, was careful with everything. Everything went perfectly. The unit is tight, no leaks, and it's such a pleasure to no longer hear the dripping of water. The pressure now moves the waste out completely, with one flush. Will not hesitate to purchase this unit again if the other toilet pressure tank follows the first. Thanks!!

Ordered on-line, received repair kit very quickly. Just now finished installing, absolutely no problems! Instructions in the user manual were comprehensive and left no doubt about anything. Very good instructions!! I took my time and still had everything done in one hour and ten minutes. No adjustments were necessary, everything worked perfectly on the first flush. Thank you for a great product and great customer support!
