I had no idea whatsoever of what was involved in cleaning out a sump. I phoned Milani & I was put in contact with someone who explained everything in a very easy to understand , patient manner. He asked me open questions that indicated there was possibly another problem, but he suggested that it need not be repaired as the possibility of this causing a future problem was minute. So I didn't feel he was trying to sell me on doing unnecessary work, & didn't feel any pressure. When I phoned back 2 days later to book an appointment, it was done the following day.
