Why would sink run when bath tub is turned on? Here is a link since no one believes me :) https://www.facebook.com/photo.phpv=10151606315118748¬if_t=like

try running all the water in the whole house at once. all toilets. outside faucets, washing machine, ect...
assuming you have no leaks.

You always need to vent a sink. If you do not vent the sink it will create a vacume and **** water, or air from the nearest fixture.. example, if you connect to the sewer line near a bath tub, when you run the sink water it will **** air from the bath tub drain. If it sucks a lot of air, you will smell the sewer odor since the water is no longer blocking it.
If you cannot run the vent to the roof, there is an in wall vent valve called a studor vent that may work. Get with someone at Lowes or Home depot to show you one.

The companies don't recolor fixtures but there are bath refinshing outfits that do. There are also do it yourself kits to be had. I did a harvest gold shower once and it still looks good after 7 years.

mite have intergral stops behind escution plate (the big round cover plate with 2 screws) that needs to be turned to the on position..

Normally a dehumidifier will run based on the humidity found in the air in the room it is located in, although many can be set to run all the time.

I don't believe your model can be set to run next Tuesday, Wednesday and Thursday because you will be home and th NOT run next Friday and Saturday because you will be traveling, for example.

Your machine should run on automatic until the bucket fills with water at which time it should stop running until you empty the bucket. Many buckets offer the feature of adding a drain hose you can run to a drain somewhere. Some people have a floor drain they use for such purposes. Others I have known sit the device on the counter and drain into a sink or in the bath tub and drain that way.

For best dehumidifying results, you should run your machine all the time.

I hope I have answered your quesiton. Thanks for considering FixYa.com

It could be back flowing into the hot water heater tank which is not full because of the leak. Even though the valve is closed on the cold water entry side, there is probably no valve on the exit side. That is how it is returning to the tank.

The soapy water will fill all of the jets, tubes and the pump assembly. Will it hurt the tub if the jets are not running? The soap film will build up in the jets, tubes and pump assembly and can possibly cause damage if the tub is run at a later date. Contact the tub manufacture and see if there is a safe bubble bath you can use.

At the base of the plug there is normally a stud with a thread on it to allow you to raise and lower the plug so that it seals or empties.

If that is not how your oulet is made then there is a lever behind the or to the side of the outlet underneath the sink, that also is adjustable on most sinks.

Sometimes it is via a spring clip which rusts and loses its grip

the most common reason for a drain to leak is that the plumbers putty around the drain where it meets the sink or tub has dried out and has a crack or void in it. Unscrew the drain from inside of the tub and check the plumbers putty. There is an inexpensive drain wrench sold at hardware stores, lowes and home depot that makes this an easy fix.

its not a bad idea i always did and never had a problem use strucolite lite weight cement
