Recently moved into a new home with a sump-pump that was not plugged in. When I plugged in the sump-pump, the unit started to emit an oil smell and make weird noises -- turned out that the unit was old / clogged / and leaking oil, thus needed to be replaced. I submitted a request via Homestars and instantly got a reply from Master Drain & Water Works. I called and spoke to Vitaliy who gave me a range of options --- I opted for a sump-pump with a back-up sump-pump that was powered by a battery. He was able to install the following day at a time that was convenient to me. Everything was installed perfectly, and to my satisfaction, I would recomend Vitaliy / Master Drain and Water Works again!
