20 Most Recent American Standard Contemporary Kitchen Sink Liquid Soap Dispenser - 4305.20... Questions & Answers

Try removing the **** Trap under the sink, there are two nuts one on each side. put a pan under the sink to catch the waste water in the trap first. ext loosen the nuts with a pair of channel locks or a pipe wrench turn the nuts counter clock wise direction till the nuts are loose slide the trap down and empty the contents of the trap into the bucket. Use rubber gloves so you don't get sick from germs. If the **** trap is plugged use a coat hanger to push threw the trap to get whatever is plugging it out. Rinse in a different sink, If it has the rubber gaskets I would recommend replacing the gaskets. Install in reverse. Do not over tighten the nuts or you will have to replace the parts. the trap looks like 2 opposing J .

All soap dispensers work on a siphon principal. There are o-rings inside these pumps and, over time, they dry out (even when surrounded by soap (which has an acid base)). Unless there is a way to dis-assemble these pumps and replace the o-rings, you may want to start looking for replacements.

The "bottle" screws in from the bottom. The "pump" is inserted in the top. I usually fill mine from the top without taking out the bottle. Too much of a pain. Just make sure the large nut holding the hardware in place is secure before you start assembling the bottom and top. If it's loose, the whole thing will wiggle around. Good luck!

That's where a mechanic has a feel for things and just looks for any set screws or threads, a handyman might help with this for you.

either the water is turned off, the pipe is blocked or the handle is stuck or broken. I would recommend that you call a plumber.

Hello. You will find that the bottle will come out once you remove the nut under the surface of the sink.
You have to get into the cabinet to do this. And, a faucet wrench, available at any hardware store will assist you greatly. Regards, joe

Depends how old your toilet is, it may be a calcium build up problem on your little inlet pipe inside your tank, but first check your water shut off valve on left side of your toilet near the wall....It may not be open all the way OR the valve has an issue...

Hey, One thing is that maybe there might be some loose plastic shavings in the fill line. From the Factory? or maybe was inside the water line going to the toilet when you connected the line to toilet. Shut off the water and get some towels and something to catch the water and disconnect it from the toilet and use bowl or what ever to catch the water and slowly turn it on and see if anything comes out. Maybe if it is in the line inside the toilet it might fall out by lightly tapping on the fill line inside the toilet to help it fall out. Just a thought when you said it "Sings" that sounds like trash inside the line going to the filler tube and bowl, hey try it who knows it might work. Okay

First, carefully remove your tank lid, and place it where it won't break or fall. Look for a four-digit number located on the back of the tank, near the water level mark. This is your tank model number. If the number starts with a two, it is a one-piece toilet.

Good Luck!
