I had a leak, called at ~7 PM when it was identified, called more vent and 5 others none of which have emergency service (can you say scam). More vent arrived as scheduled. I told the tech what was happening. He replaced the valve and while writing up the bill, the toilet water started up again as what I described to him when he arrived. He said oh that's not the float (which is what I tried to replace starting me on this journey) it's the flapper. So in the end between a value and flapper that ran over $400. I need to find a local plumber and one of these companies.
