Heart (and wallet) warming news from the USA where calling out a plumber has led to a householder getting 24 years of sewage charges repaid (see http://www.vcstar.com/news/2010/jul/22/the-outcome-fits-the-bill/).
It seems the lady did not know she had a septic tank until the plumber told her (an impressive record of reliability is implied for the tank system!) and she has therefore been needlessly paying charges for sewage disposal.
It is nice to know that calling out a plumber can produce such a financial windfall. It is not actually part of the Drain Doctor “promise” but is totally in line with the philosophy of ‘dazzling service’ and ‘going the extra mile’.
