Hello,

I'm having a problem with my shower and toilet, when I'm taking a shower and I'm in there for more then a minute my toilet start blubbing and then my shower is backed up, it takes about 30mins for the water to go down, I can't use my toilet in the master bath or the guest bath, but the 1/2 bath down stairs is fine, I've tried putting drano down my tub and put plunging my toilet, but that hasn't work. What else can I do.

From what you describe, it is clear that there is a serious blockage in one of the drainpipes.
Try more drano, or pour caustic soda crystals down the drains, and follow that up with a couple of liters of hot water. Repeat that sequence and leave over night.
Rinse the next morning.

Use plastic gloves as caustic soda is bad for your skin (but good against blockages) :)

Success !

Sounds like you have a clogged vertical drain pipe there Faith.

I am afraid that if you want to resolve this so you are not messing with this again in 2 or 3 days... ;)... you, you and a friend, or a plumber need to snake the drain line.

In order to snake the drain line you or others will need to either snake the drain from the roof vent (if not to steep an angle at roof) or will need to lift the toilet CLOSEST to the vent stack going out the roof (just go outside and see which bathroom is closer to the pipe going out the roof) and snake the drain from there.

The proper snake for this job can be rented at any rental store... see pic. Below. It is a medium size cable machine and requires leather gloves and goggles to work with it safely.

If it was my house, I would lift the toilet (set aside on plastic bag for now... remove the LID! ) and then fill the drain line using the shower to close to overflowing the toilet pipe... then send cable down the drain (with a small retriever head) so that when it hits the blockage the water will bob up and down a little (or release entirely) which is a signal that you have hit something and probably want to try to PULL IT BACK if possible.

Anyway, that's my take on this. In the long run I just don't see that chemicals will do much with a blockage like you present!

Let us know what you do... or if you have any more questions... MARK

Stop with all the caustic stuff now and add water when you can to slowly get the stuff out of your work area. I know they sell tons of that stuff but it can be dangerous. Rodding is the best approach but clean the lines first.
