I'm considering replacing a 5hp Briggs and Stratton/Davey water pump I've had sitting up by my dam for 30+ years. It's permanently piped [is that the correct expression] in though it's not used regularly and can sometimes sit for a year without running. The water supply it supports is a syphon with about 10 metres head and 500m of 1.5" pipe. It's been reliable and durable and provided I can get the parts, it's probably good for a few more years work. It's also there in case of bush fires.
Anybody care to suggest a good replacement? Honda/Onga have been around forever and have a good reputation but I see there's quite a few other brands around that I'm not familiar with, though they might do a good job, as above. Reliability and durability rate higher than sheer performance but I don't need to get into anything at the diesel level given the engine won't get a huge amount of work.
