Hi again Joe

Plumbing trouble now? The pipes with some type of glue are indeed glued with PVC Pipe Cement. It melts seals and glues the pipes together. The only way to to cut and put in a joined, once again glued. Normally you only undo the threaded connector under the sink waste, and the water trap that is attached to it.

I have a mobile home single wide older 1978 snaked auger type 25 feet kitchen sink drain still clogged

I had this issue about 6 years ago and the big(3 1/2") black ABS has probably colisped somewhere therefore all that water/sewer cannot go through. My was underground , so I had to hire a backhoe to dig up and install new black pipe. Years ago contractors used a cheaper black pipe and it did not stand up. If your black pipe is good, then it will be plugged at a P trap somewhere or it may be near the join close to the town/city connection...Where or what water/sewer is not going through...If your bathroom goes through, then It will be your kitchen drain...If its your kitchen, then the P trap is plugged under your sink.Replace it under 20 bucks..and make sure its 1 1/2" in diameter...they may sell you 1 1/4 BUT don't use it...

How to disconnect sprayer hose on kitchen faucet?

Turn off the water supply valves beneath the kitchen sink. Turn on the faucet and squeeze the trigger on the sprayer to empty any water left in the supply lines, faucet and sprayer.
Trace the sprayer hose from the end of the sprayer to where it connects to the faucet. Use pliers to loosen the connector holding the sprayer hose to the faucet.
Remove the sprayer hose from the faucet to expose the male threads. Wipe the threads dry with a towel. Wrap the threads with pipe-joint tape. Twist a 3/8-inch threaded brass flair cap onto the male threads. Use the pliers to tighten the cap.
Reach beneath the sink and loosen the mounting nut securing the sprayer support to the sink or countertop. Use a basin wrench if you are unable to reach the mounting nut with your hand.
Slide the mounting nut off the hose attached to the sprayer beneath the sink. Pull the sprayer support and the sprayer from the hole in the sink or countertop.
Insert a sink hole cover into the hole left by the sprayer. Depending on the style of hole cover, it could snap in, or a mounting nut could hold it in place.

Things You Will Need
  • Pliers
  • Towel
  • Pipe-joint tape
  • 3/8-inch threaded brass flair cap
  • Basin wrench
  • Sink hole cover

Need to remove garbage disposal

First disconnect power at breaker. Next disconnect power cord from the bottom side of disposal. Next, loosen large nut holding disposal in place under sink. Next, you will loosen bolts for frame and the rest is just removing small parts. The first 3-4 steps are crucial especially with power. You will find during this process the plumbing which is attached to a parallel plastic pipe. You will want to disconnect this right after you disconnect the power cord from the disposal. This will give you room to work a little more freer.

One of the grinder broke inside the unit, is this a replaceable part?

If disposal has loose parts inside, you have to replace the disposal.
If disposal still work and doesn't vibrate and loosen pipes under sink, then it's ok.
The don't sell replacement parts for disposals.

I wrote tips for replacing disposals:

When I worked apartment maintenance, we replaced disposal with same brand disposal.
That way we didn't have to change out sink basket or move pipes around under the sink.
How to: Disconnect 2 nuts on p-trap and trap falls loose.
Rotate steel connector disk that holds disposal to sink basket, and disposal comes off.
Before installing new disposal.
Attach electric wire to new disposal.
Attach dishwasher tube to new disposal. Knock out plug inside dishwasher opening.
Push new disposal up into place, and attach to old sink basket.
Use new connector washer.
Attachment ring catches at three points, all three have to connect.
Re-assemble tubular pipe.

If this is your home, you want new sink basket that comes with new disposal because it looks shiny and new.
Buy a tub of plumbers putty also.
Remove old sink basket and clean sink opening.
Put finger-size roll of plumbers putty around sink opening, and then push new strainer basket into plumbers putty.
Tighten basket from below, wipe away excess putty around sink opening.
Install new disposal as described above.

Tips for tubular pipes:
When taking apart tubular pipes, start at p-trap and take apart as few pieces as needed to do job.
On image above, loosen both upper and lower nuts, trap falls loose, and then work on disposal.
Any tubular drain pipe that gets moved while working under sink needs to be disassembled, cleaned and re-assembled.
Metal pipes have rubber washer >> always use new rubber washers.
Plastic pipes have plastic washers > plastic washers can be cleaned and re-used.
Plastic washers have flat side that goes toward nut, tapered side away from nut.

When reassembling tubular pipe, we use rectorseal on washers and joints.
Slap a good amount on washer just before pushing washer in place and attaching nut.
Rectorseal will ensure tubular drain pipes won't leak.

Garbage Disposal is about 2-1/2 years old It is now no longer grinding up potato peels and clog every time! HELP--do we need a new one!!!

1/2 horsepower is the lighter weight model, and if you use it heavily, then it will not work like before.
Another thing to consider is whether the water is draining away completely while you're cutting.
If water and potato peels are both present, your p-trap and tubular drain may need to be cleaned.

While using our garbage disposal this afternoon, it went from grinding to humming. The blades do move freely, but the plate is very loose and tips. Is it possible to tighten the plate?

There is no way to tighten plate that I know of.
Maybe a clever welder could stick it back together, but the problem implies something underneath is rusted out or broken. The main thing is the cutter plate, and if disposal wobbles, it will loosen drain pipes under sink and cause dripping.

I wrote some tips for installing new disposal, and include them here since disposal will be replaced at some point.

There is no way to loosen this pipe if it has been glued. You only option is to cut the pipe and either add a section back to it, cut it and put a coupling in.

How do you remove it so you can replace the sink

To remove the diposal, do this:

Turn off the power to the disposal first

Under the sink disconnect the wiring to the disposal - this requires removing a cover and usually a couple of wire nuts. Then loosen and pull the connector out, replacing the wiring nuts after you do that. Some disposals are pluigged in under the sink. If your is, just unplug it.

Under the sink, disconnect the drain pipes to the trap

To remove the disposal, there is a keeper ring with three loops protruding from the sides directly under the sink. Note the position of the disposal under the sink so when you put it back, the drain pipes will fit again. Insert a short phillips screwdriver or pin punch into one of the loops. Support the disposal under it, then rotate the ring counterclockwise. The disposal should come loose. Be careful - they can be a little heavy.

I have a dishwasher whirlpool DU945PWSQO I like to know if i have to used hot & cool water install to the dishwasher. Or i have to used hot water only

Hi,
You only need to hook your dishwasher up to the hot water only. You can run a separate pipe from any hot water pipe, but in most kitchens the dishwasher is next to the kitchen sink, so the hot water is just teed off of the piping under the sink...
