Fantastic
Upgraded the noisy shurflo 1.1bar pressure pump in our touring caravan to the seaflo 42 series pump and added an accumulator tankHad to rewire the pressure switch feeds on the pump to suit the wires in the caravan for it to function correctly in my setup,There's no issues with the product atoll,Just had to be wired to work correctly.Fantastic value for moneyLow noise and Fantastic pressure

Good value price tag for a comprehensive 12v pump Seaflo appears to continue to increase product range and quality year upon year, fair play.

Excellent pump!
I have had similar pumps from different manufacturers and they cant stand even close to this one!I was shocked how quiet it is and how small the vibration is. pressure is very stable and it is powerfull.Shortly- very well built and definitely worth the price!!!!

Ample power, good features
Plenty of power for water main type pressure for garden hose. Bypass feature is great for reduced flow requirements without constantly cycling on and off - although it does a bit when turned right down, but you don't use it that low anyway. Auto off feature works well. I have tried several others and although they have the pressure, they do not have enough flow and they don't have the special features mentioned above.Very pleased with this.

Bypass valve is so worth it.
Just amazingly fast shipping. Super nice pump. Had the seaflo 33, which is also great, but it cycles all the time if you only want a trickle out the faucet. This one (42)takes care of that with the bypass. I would always go for the 42 over the 33 unless you just need water for a garden hose. Only downside is that it came with no adaptor plug. Just two loose wires.

Super piece of kit
Super piece of kit, solid sturdy build & very quiet compared to my old water pump. Would definitely recommend & buy this product again

Not as shown
I ordered one as a replacement for one I'm already using Sept 18 and have just got round to using it. I now find that the pipe fittings are not the screw type as shown in the picture, which I need. As I now can't return it as I'm outside the returns window, it's no good to me so 1 star.

POOR QUALITY
Poor quality, and not as described. The pump does not reach pressure and automatically turn off, so have to turn of manually. No Air or leaks in the system so why does it not turn off. Would not buy again and will return to a shurflo pump.
