Abusing this pump and its still going
I work in a quarry and have this for dust suppression on a crusher, been using it the past month now it's dry and it's running 8-12hrs a day 5 days a week. Most it's pumped in 1 day is about 4k litres with the bypass and pressure screwed to the max. It's running 1-4 nozzles (2 sprinkler and 2 hand type. the sprinkler in the picture is giving more water than it looks as its windy and hard to see where its that fine a spray) depending on how dry it is and sucking water out of dusty ibcs. Not much else you can ask of it when the pump it's replaced was 7 grand. The spray from the hand type in the picture is with 3 nozzles turned on at once on a flat setting.

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

Extremely quiet ...top notch
Replaced my Jabsco pump which was very noisy for this seaflo 42 and what a difference fantastic product and 20 times quieter...I also changed the accumulator which together work perfectly 👌

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.

Fantastic
Upgraded the noisy shurflo 1.1bar pressure pump in our touring caravan to the seaflo 42 series pump and added an accumulator tank Had 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 money Low noise and Fantastic pressure

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.

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.

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!!!!

Excellent product. Super quiet, very easy to install, perfect fit for my setup, very well made. It comes with a rubber base to absorb vibrations which makes it quieter than it already is. I’ve been using it daily for about a week now without any issues. My daily use is basically to water my garden which takers about 30 minutes of continuous use and supply a toilet and a sink that are off grid. Suction head of my setup is about 2 feet and the other end head is about 10 feet, no issues at all, pressure is great and the auto shut off works flawlessly. Mine is powered by a small battery bank of about 50amps that is connected to a wind generator so is completely off grid. If you want a quiet, powerful, easy to install, great quality 12 volts pump; look no further this is the one you need!!!

Ja det är vad jag planerat, för mitt kök på landet, bra tryck och lätt ljud, slutar när kranen stängs. Jag giltig. Carina

We have used this product for 1 1/2years at our off-grid home. The only time we’ve had a problem was with ‘low voltage’ causing the pump to run on.. this was easily fixed on our part. We have purchased a second Seaflo pump to use with outdoor operations spring to fall. This reasonably priced, quiet, reliable pump is a true winner! The customer service for this pump is also quick to reply.. very friendly and helpful.
