MY toilet was leaking from the bottom without being used. Brown smelly gunk came up tub drain. Plumber snaked all the way to street, said it was paper towels that cased the problem. Everything fine for 1 day. Now toilet makes gurgling sounds when not in use but after shower is on or main bathroom is being used. Called plumber and he said someone must have put something in the toilet. That was impossible since I was the only one home. I don't know if this is connected or not but hot water pipe in backyard burst about a month ago and plumber came out and replaced it and the pressure in kitchen faucet and my bathroom sink is low.

Call the plumber to come and snake the vent from the roof, Regarding your faucets I would suggest to remove the Aerators from the spouts open the faucet see if water flows is good if it is clean the Aerator screens and install see the image below, if the water flow is no good when the Aerators are remove problem will be with your supply lines or the angle valves, come back and some one will tell you the next steps, Thank.

Plumber obviously didn't do a good job. Usually, drain cleaning companies give you some warranty. Blockage should not return after a day or two.

Roots in sewer pipe is a problem. You will never get them out - unless you replace entire length of pipe. However, you can control it by periodically having the pipe cleaned. I would call company that Hydro Jets sewer pipes. That way you can be assured most of the roots are cut at the time of cleaning.

As far as faucets go, do as John suggested: clean aerators.

Hope that helps
