Great Pump for the cottage

Have been using it for 6 years now, always starts, easy to maintain. I use 200 ft of fire regulation hose to cover my property lawns and gardens. I can water everything in under 30 minutes and draw my water from our river. During the hot dry summers we have up here in lake country its a great piece of insurance, I keep it ready to go incase of emergencies, great piece of mind. The sustained pressure is incredible even at 200 ft and I suspect I can attach more 50 ft sections if required ... Honda dependability is worth the extra $$

I bought this pump as some additional protection for my property as I live in a rural area prone to fires. I have no allusions about fighting a raging wild fire with it, but it could make the difference in certain situations. I was young once and used this pump as a firefighter. If you're the guy that would get the garden hose out to stop a fire moving towards your house, then think what it would be like to multiply that effort by ten. You can buy cheaper engines/pumps for this purpose at the big box store, but if you want to sleep better knowing the darn thing will start, prime and shoot water in a high pressure stream, then consider spending the extra coin. Be aware that it comes with kind of an uncommon thread type on the outlet when buying fire hose for it.

What can I say about this pump? Had it for 12 years in my yard irrigating the lawns with upto 400 feet of hose at a time. This pump works great - never a loss of pressure, and always starts 1st pull with little maintenance. Pushes water uphill with a total head of over 50 feet.
