I've had an electric septic tank for close on 20 years. The first pump (The one in the tank from new) was a titan goliath th. It lasted nearly 15 years. When it finally gave up, I went to the people I bought it from and they provided me with another for the princely sum of £200. I fitted it and off it went. The second pump (also a goliath) failed after 2 years. I took it back to my supplier who opened it up and informed me the seals had given way, the unit was flooded and was wrecked. They also told me that they had started using a different pump in their tanks as the goliath was not as reliable as it once was.
For another £200 they sold me the new pump. Two and a bit years on, and it has failed too. For a few weeks there was a rumble from it,like a bearing rumble, and then it packed in.
I know if I go back to my supplier they'll sell me another pump for £200 But if it's only going to last 2 years I was wondering if any of the cheaper ones available would last as long?
Or is there such thing as another bomb proof pump that will last me another 15 years? If it'd last I'd be happy to pay a bit more.
It's a bit of a specialist long shot for PW but if there is anyone in the know out there I'd be delighted to take advice.
