My toilet has black mold coming from the holes where the water enters the bowl. It builds up monthly. Why?

Question

The house is brand new (less then one year old) and I am the first occupant. I haven't noticed anything else unusual in the bowl or tank. Even the tap water seems to come out of the faucet looking/ smelling normal. There is never any black residue in my sinks, showers or bathtubs. If someone has any suggestions/explanations for me, I would appreciate the feedback.

Answer 1

There are toilet bowl cleaners that look like a giant tablet you put into the water tank of your toilet. It treats the water in there and kills than funk as new water comes into the bowl.
I don't know what it is either but I had the same thing and that is what keeps it from coming back.

Answer 2

I had the same problem, in another house, located in South Florida, where all conditions combine to make for globs of the stuff to form weekly.

The black mold builds up on on the outlet because they are not Strong enough to push the bacteria that is in the TBowl away, and molds grow in length.

It's a combination of the water supply and other factors, most of which I don't know, such as pipe construction, geographic region, water quality, water source and personal habits.

I used the Clorox tablets which work, but they degrade the flapper in the tank. Twice a year in this house I was replaceing the flapper. I got a heavy duty one. I don't really like Clorox, it ends up on you, no matter what, and will bleach out any fabric that comes in contact with it.

I don't have the time nor patience to be carefull with things that are really problems, not my fault, but shoudn't be used in the house if they are so toxic or dangerous.

Also, when putting tablets in the tank, you need to remember never to use amonia to clean the Tbowl, otherwise the two combine to create dangerous fumes that really will hurt you.

I washed the bowl down with 7th generation cedar oil, but I read plain old white vinegar will do.

Why spend money when you can pour cheap white vinegar, not harm full to pipes, sewage systems and the environment?

Plus, I am not the sort that is going to peer regularly into the tank. Once a week, before bed, pour vinegar in the TBowl and drains. The overnight soak will work, and it turns out, vinegar is the one product that really does do thousands of useful things.

And it woun't mess up the spetic/sewage lines, you or your Tbowl flapper.

First of all there are some things that you haven't told us, such as: are you on a city or county water supply, a well or cistern. If you are on a city or county water supply you might want to call the city to see if they have flushed the mains here lately. If you are on a well it might be a good idea to have your well water tested to see exactly whats in it, (they take a sample at the faucet and the well to determine if the problem is in the well or the plumbing itself. Last but not least, If you are on a cistern, your cistern might need to be cleaned out and you might need to consider getting a new water supplier. What it all boils down to: "is it the water or the pipes"

Mildew forms in humid environments without much circulation. It could be that you just need to leave the lid open or get more circulation into the bathroom. But the easier situation is to just clean the toilet. There are certainly plenty of products you can drop in the tank (ie., 2000 Flushes) that would stop this problem from continuing.

Answer 5

do not...i repeat, do not put any of those bleach based, or any other type of bowl cleaner in the toilet tank. they are harmful to the rubber goods in the tank, i.e. flapper, and ballcock or for you ladies, tank refill valve. carefully take the lid off the toilet tank and set it down on the floor out of the way. put your hand in the tank and if there is a black flapper with a small chain attached to the tank lever, hold onto the edge of the rubber flapper with your thumb and forefinger and rub them together, if your fingers come back black...which i know they will.. it is time to go to a plumbing supply house and purchase a "korky" flapper, the red one. the house is new. i understand that. more often than not the plumber installed a "builders line" or inexpensive toilet and the rubber on this flapper is deteriorating and leaving black deposits around the flush rim of the toilet.

Answer 6

There may be a real tiny leak. Or there is condensation present. It definetly has something to do with moisture. If no leak, try putting some plumbers putty around the inlet after you clean off the mold. You can use bleach to clean and kill the mold .GOOD LUCK.

Answer 7

you may have a Ph problem. Try getting a bleach based toilet insert. It's the kind you drop in the tank. If it continues you should have a plumber look into it. It sounds like something in the pipes maybe...do you have any problems like this in your sinks? Maybe in the kitchen sprayer? I would filter my water to drink until I found out for sure what the cause was.

Answer 8

Heres a tip to clean residue out or your toilets, sinks, shower or bath tub drains. Mix together 2 cups vingar, 1/2 cup baking soda, wait till bubbling action stops and flush down with water, this is safe and non toix or poisonous.

Answer 9

You need to clean your toilet once a week! Throw away the single use bowl scrubbers! Get some bowl cleaner and a real brush! You will get your bowl a lot cleaner!

Answer 10

Buy the bleach tablets that you place in the tank and make sure to clean the bowl weekly with a bowl cleaner (try Clorox or Lysol brands.)
