Our DishMaster M76 Imperial Four was leaking and after adjusting the handles, per instructional video, the drip continued and the handles were hard to turn. We ordered and replaced valve seats and union O-rings (K31230), torque free valve ends (K0858) and valve stem bushings (K1075) and now it’s working smoothly without any leak, just like new. Highly recommended maintenance kit!!
Glad we could get you back in business, thanks for your order!
When I called Chris and explained the problem, he knew immediately the parts I would need to fix the problem. They were sent out the same day and worked out perfectly. The repair solved the issue. Very pleased!!
Used dish master since 1957.
A Proven Unique Product
Worked ok needed to be done
Cold water valve kept acting up, changed cartridge, then bib washers. Opted to replace seats and fixed issue. Old seat looked like it had a small ding-like mark on it. May or may not have the culprit but replacing it has made a world if difference and the videos made it very manageable.
The parts worked great and went in easily. The service man wasvery helpful.
It's horrible to be at the mercy of Dishmaster's extremely high prices for these replacement valve seats that end up developing cracks/splits yearly and cause the faucet to drip. I live in a 50s home and no other faucet in the entire house (even the shower) develops pitting/cracks as soon as these valve seats do. My pressure is properly regulated to 55-60 psi, and the water isn't heavily mineralized. The sink doesn't get an abnormal amount of use either. The brass is of low quality, not polished, and the valve seats have micro machine marks that contribute to premature flowline erosion. My M76 Imperial four faucet costs me about $10/month in maintenance for all the parts I have to replace. I have a bathroom faucet that is 15 years old from another brand and it has never needed any maintenance. Can't wait to do a kitchen remodel and go with a standard faucet.
The valve seats are made from high quality C69300 lead free brass. Prior to your recent purchase, you last purchased seats in November 2023. Thus we agree it appears that in your situation the seat must be replaced on the hot valve once per year. This is not uncommon. Hot water accelerates faucet wear primarily through the accelerated mineral buildup (limescale) deposits, especially in older steel pipes, and by causing components to expand and contract more significantly, which leads to quicker degradation. These dissolved minerals then precipitate out of the water and build up as scale deposits inside the pipes and faucet, particularly at the valve seat. Unfortunately we are not able to overcome the conditions.
I haven't installed mine yet. I got them in advance of trouble, since my dishmaster hads a few years on it. Your customer service is msuperb!!! Thanks.
Ordered replacement parts and spoke with Customer Service and they recommended the parts to order and then emailed installation instructions and videos, very nice touch and most helpful, installation was quick and easy, highly recommend these folks!

Quality product. Great service. Promptly shipped
Everything seems to be working perfectly. OUTSTANDING customer service!
Videos are a great asset.
With helpful advice and info, replacing old seats was easy.
We called Dishmaster customer service and they helped us order the correct parts and solved the dripping faucet issue we had. New valve ends and seats fixed that up right away and now the faucet works like new again. Great service and very helpful.
We are retired for 20 plus years. She cooks and I wash and clean up afterwards. She wants a new looking faucet. The deal is, we can get one, but I only wash dishes and clean up with a Dishmaster. We still have a Dishmaster. The valve seats and O-rings stopped the leak. Thanks
Thanks for your review. Has your wife seen our Sapphire faucets?

My hot water seat had cracked. The replacement set fully resolved the issue. Thank you.
Great customer service. Chris was very helpful and answered all my questions in detail. I’m proud to own a dishmaster faucet. Thank you
Easy to install, just barely touch the handle and the water is off, no more dripping !
INSTALLED AND EVERYTHING IS FINE NOW, NO PROBLEMS!
After purchasing a few valves, Dishmaster reached out and diagnosed the issue, sent me the correct part at no charge and presto, faucet works as good as new. Technician is very knowledgeable and patient. Great job!
Step-by-step instructions come with the parts but can also be found here on the Dishmaster Faucet website. All I needed was a standard wrench and an allen wrench. Took about 20 minutes because I was going slow and steady to prevent mistakes. I’m constantly amazed at the quality design of the Dishmaster Faucet for easy repairs.
Easy replacement and fast shippihg
I have had a Dishmaster since I was 30. Each time I moved I would have one installed. I'm now 80 and can't imagine life without a Dishmaster. When something goes wrong, if freak, but the helpful people at Dishmaster can make everything OK.
Thank you
Works well. Very pleased
Nice product.
The hot water drip and dripped…ordered the parts…got them within 3 days..when I took the unit apart..the supply seat was pitted and was the cause of the leak…new parts were perfect and the job took under 60 minutes to complete…our unit is 8 years old..the Florida swamp water destroys everything….
Hot side still leaks unless turned off with extra push.

The replacement parts you sent me work perfectly. I had to wait until my son could come and do the replacement for me and that's why I am so late in responding. I love my Dishmaster Imperial Four!!!
