My plumbing experience was to have the plumbing disconnected under the sink so the counter top and new sink could be installed. I thought the service of $115 was high, but usually if there is an additional fees, it is usually rolled into the cost of repairs or labor. This company also charged 3.75 % for putting it on a credit card, which was not mentioned until I received the invoice in the mail after paying on the phone.
When a person has a blockage in their sewage system they often try to fix it themselves by adding an acid or a base such as Drano in an attempt to dissolve or dislodge the problem. These chemicals can get into the plumbers eyes when the sewage is splashed during the repair. The plumbers skin during the repair does come into contact with the sewage water. The owner of the toilet might not report to the plumber they have already tried Drano a highly caustic base .
