Hi -- I'm a 61-year-old widow with no family within 2000 miles. And here I am with water problems. Ugh. I am wondering if I should check the roof vent for toilet or if you can tell from my problem description if I should restrict problem-solving to sewer/water drains/lines. Note that I live in a rural area where the
* First noticed water draining very slowly when flushing.
* Next noticed hornet nest built inside air vent on roof above bathroom (also in both mirrors of truck, under hood.. etc. amazing!)
* Then noticed water in shower in that bathroom was starting to drain slowly
* Poured about 6 ounces of Marc 55 concentrated sulphuric acid into shower drain (using an opened tuna can on drain to avoid splash, which sure does help)
* Result was water drained fine from shower but when running shower water for three minutes (timed it) at full strength water began to back up.
*Toilet situation unchanged
* Ran water at full strength in kitchen sink for five minutes and it drained perfectly but only for five minutes. Then while it continued to drain, it began backing up into shower
* Poured just a few ounces of Marc 55 into low water in toilet and added immediately 2 gallons of water. Water level simply reached top of toilet bowl from the added water and then returned to normal water line level. Not sure if this is what is suppose to happen. Did not flush
It's the weekend and I'm now wondering if I should climb ladder and see if vent plugged or see if I can find a willing neighbor.
Any thoughts on whether that's something that should be checked?
