Waste King advantage

I replaced a Sink Master 1/3 HP disposer with a Waste King Legend 1/2 HP 9930. Sink Master is made by Waste King and is the cheaper model. The Sink Master had a galvinized grinding chamber which rusted out completely after 20 years but the motor still ran fine. The new Waste King has a stainless steel chamber and I expect a good 20 years or more from this unit. The direct current motor is a major advantage over other disposers. It has a higher starting and low speed torque than induction motors of the same horsepower making it virtualy stall and jam proof. Even my old 1/3 HP Sink Master didn’t jam and the seals never leaked.

Highly Recommended — get this one today to replace your old badger

When they say this one is a replacement for the insinkerator badger they are not kidding. It fits exactly in the old spot occupied w/ old one. I was worried that one cross pipe (horizontal PVC pipe) would not align as in old 3-bolt mount Badger 10, but it fit to the T, making installation a no-brainer (if it were any wider to higher/lower, then it would not have fit existing pipe). There are many instructions, but they are very detailed (in a good way) and very well written. Also there are videos online. I never installed a disposer before, but was able to get this one the first time, with no leaks or problems. Works way better than old corroded disposer…. this one is stainless steel so won’t rust. Also, has a higher rpm and torque than old, even though old one was 6.7 amps, 1/2 hp, this one is 4.5 amps, 1/2 hp, so uses less power and more torque amazing. This brand is way better quality than insinkerator. Light weight. Just couldn’t ask for better. To me sound is about same level, but little higher pitched due to higher RPM, but most reviewers say its quieter. Wow.

Easy install, sounds like a biplane, sink drains slowly

Bought the 1/2 HP WasteKing with 3-bolt mounting system to replace an In Sink Erator Badger 5. Was swayed to 3-bolt version of WK based on Amazon feedback, specifically reviews discussing ability to mount to an existing In Sink Erator sink flange. In fact, it’s not possible to use the ISE 3-bolt mount system for the WasteKing 3-bolt system. No worries, just needed to go buy some plumber’s putty and put in the WasteKing flange. Very easy, even though I had zero plumbing experience before this. For our undersink plumbing, the WK matched the ISE dimensions perfectly–no need to change plumbing at all. I suspect these things are standardized.

Replaced an Insinkerator Badger 5, which had started to leak through the bottom after 8 years of light use, with the 9930.

Works great – not as quiet as I thought

I purchased this to replace an InsinkErator that was 10 years old, builder grade original to the house. I was hoping to upgrade in quality and noise as my old one was 1/4hp and noisy. I opted for the 9930 over the cheaper, same horse power 9920 as it seemed to have a little bit better insulation. Not really sure if the extra $15 was worth it as I can’t compare it against the 9920, however I can say it is not much quieter than my old disposal. I kept telling my wife how quiet I thought this one was going to be and we were both disapointed when it pretty much sounded the same. To be fair the disposal does do a good job of taking care of whatever is thrown down and a definate improvement over the old builder grade one. Bottom line if you are hoping to get a quiet disposal to replace the common InSinkErator, I don’t think this is it, however if you are looking for a disposal that does a good job at a price less than the local box stores this will work.

I chose the Waste King 9930 for it’s good reviews, 5 year in-home warranty and no leak lifetime guarantee.

It was silly for me to assume this model will install directly to the existing mount of the failed Badger brand garbage disposer. Lesson learned is regardless of the model, change the mount and do it right. So, the Waste King 9930 uses a 3 bolt version and it went in as easy as the old mount came off. It took longer to clean out the old putty than to install the new flange and mount. The recommendation to use dish soap on the hush cushion when attaching to the included sink flange was spot on. The 9930 was light enough to do a two hand install. The hush cushion simply snaps into place. My setup uses an outlet so it was great the 9930 has a power cord already attached. I needed to trim the discharge elbow with a hack saw for proper alignment. After tightening all the screws, I tested the disposer and it worked just fine. It operated quietly with a brief noticeable click when starting. Other steps learned included cleaning dishwasher discharge tube, fixing additional pipe leaks (there will be several, typical when working with plumbing), and record the serial number before installing the disposer. I allotted at least 1hr for my installation but it was really shorter. It took longer for me to figure out how to detach the new flange from the hush cushion as shipped from the factory. The owner’s guide did not mention that step. Otherwise, enough information was provided to allow DIY installers to get it right the first time. I chose the Waste King 9930 for it’s good reviews, 5 year in-home warranty and no leak lifetime guarantee. Although my other unit lasted way past it’s operational guarantee, I expect this Waste King 9930 to last even longer.

Went to Waste King from Badger 5

Went from Badger 5 to the Waste King 9930 after the Badger started leaking. Install was pretty easy since the drain and dishwasher entry were pretty much in the same place as the badger. Hint – Make sure you use the rubber gasket that came on the black pipe for your existing pipe entry. Its real easy to miss. Another Hint – Like others said go ahead a clean out the pipes since you have it out. The smell of all the stuff in the pipes is pretty nasty.

Waste King A-OK

I purchased this Waste King because it has stainless steel blades. I did have to order the extended sink mount for cast iron sink as the unit comes with the sink mount for a stainless steel sink. This is important to know when you order this item.

Great Disposal

Installation was fairly straightforward (although you will need to buy plumber’s putty, and maybe a hacksaw). The hardest part was removing the old unit as it had been there for years and the old plumbers’ putty had hardened and rubber gaskets had corroded. Once we had a clean surface to work with, installing this took less than 30 minutes. A hacksaw was necessary only because the black pipe that connects to the disposer was longer than my old one, so I had to shorten it by about an inch so that the other side of the sink could still drain. New unit works like a champion so far (I’ve had it installed almost a week), making short work of everything from strawberries to banana peels. My old insinkerator (Badger 1/2 horsepower) took 15-30 seconds to clear food out of the grinding chamber; this new Waste King takes 5 seconds or less. Awesome!
