Waste king 1001 disposer is jammed and won't rotate from inside with a broom handle. Do I need to take it apart to free it up?


Should be a place on the bottom of the unit to insert a hex or allen key to turn it to break it free... if its jammed. Make sure power is off/ disconnected prior to performing this task.

5 year old Waste King AH-780-UL Quick&Hot Instant Hot Water Dispenser produces white residue in the dispensed hot water. What is causing this; what remedies are recommended? i took out faucet and the...


well the tank is made of brass and copper. That takes away that it is the unit. It sounds like lime buildup. Now what does happen as water goes into the tank and heats up lime will remain in the tank. Then as time goes buy it then starts to get to heavy and relesase itself and then the clog effect it taking place.

the best thing you can do now is reverse flow water into the tank and wash it out, its call beack washing. Yu can buy some products to put in at first to help break it down and then you get ore out.

With the new whole house units they now install a vakve set that has two way valves so you can backwash the tanks and stay ontop of the lime.

You must be asking where does the linme come from, well it starts at the well where the water department gets there water. then it goes into a filtering system and they use a lime to act as the filter agent then it heads out to the system and coats the pipes all along the way. I have cut 16 inch pipe and there was solid inch of lime caked inside.

I tell many people if yuo looking inside the water system yo would never drink the water. You might want to think about getting a whole house filter system to slow down the kime that geets in.

Thanks so much be safe in all that you do.

Water leaking from bottom of quick and hot dispenser only 18 mos old


I had the same problem. There is a 2 piece metal tank inside. The top and bottom of the tank are connected with screws & nuts, and there is a rubber o-ring between the two pieces. The grove for this o-ring is very shallow and it doesn't fit tightly, increasing the probability of misalignment during the assembly process. I was unable to fix the leak, IMHO the grove is too shallow and the o-ring is not thick enough. I decided it was poorly designed & trashed the unit.

We need the fitting that fits on the underside of the sink to hold the faucet in place.


If this is a screw thread, then check if nut that comes with toilet flush valve will fit.

Water flow is reduced to a trickle after only 2 mos. of use with the quick&heat water heater. we are in San Diego and water is nit that hard. Lawrence


Lawrence; there are several potential points that can reduce your water flow. Try these items and let me know. Check hoses under sink for any kinks.......take the aerator off the faucet and run water if trickle is still there then aerator is fine......check the valve that the water comes from and make sure it is turned all the way on. If these do not solve your problem let me know. Thx

Slow leak drips from bottom of 4 year old model


Hi

Please try and remove the cap by turning it clockwise and counter clock wise to remove it. If it doesn't come off then empty the water dispenser and use glue to fix the leak. See this link to see which type of glue should be used--- Glue Usage

Slow leak drips from bottom of 4 year old model


You can probably repair this by removing the fittings and replacing any plastic compression rings with new ones. Everything else can be cleaned with grade "0000" steel wool. This will get rid of any deposits without damaging the surfaces. ! or @ careful wraps of Teflon Tape to the MALE threads will help get a good seal.
