DC 12V Water Pump 4L/M 1GPM Diaphragm Pump 3/8" 10mm Fitting with Clamps

I’ve bought this pump and find it to be EXACTLY as the seller suggests. I rarely leave reviews but looking at others in regards this item saying things like ‘pressure switch doesn’t work’ or ‘flow is only half what it should be’ - ffs READ THE DESCRIPTION as it’s just totally unfair to criticise either the seller or the item when the only issue you have is your own failure to read the description properly and/or you own numptiness ! The pump does exactly what it is claimed to do. There IS NO PRESSURE SWITCH as the listing CLEARLY STATES, and flow is of course entirely proportional to back pressure AS THE SELLER SAYS ! Some people really are a danger to themselves

Cheap and cheerful . If a bit nosiey

Arrived on time, and works well. 👍

So often, not even with particularly complicated bits of tech (like this item) - you buy it from Amazon, (because they've made it impossible for high street sellers to compete) - and unfortunately it's just not very good. It's only £20, so any remedy just isn't worth the time - and you write it off. This seems to be how we do it these days. We opened the pump up and immediately, water came out of it - so it's probably a return. (Do they test each one before they leave the factory? I wouldn't have thought so.) Also, one of the screws attaching the motor to the pump was hugely over-tightened - the lug was squished flat. Not saying you shouldn't buy one, just beware, it might not work as described. Ours does pump water, but it won't switch off automatically. (See that other one you're looking at that's slightly different in price and description but looks the same - it *is* the same. You pay your money etc...) Not bothered about returns or refunds - might be a first world option, but I've already written the money off.

Bought this as a replacement for a Sureflow waste pump for my shower (narrow boat). Very easy to fit, but even with adjusting the pressure screw (which doesn’t seem to do anything) the flow rate is desperately low. Claims 6 litres per minute, maximum 1.5 - 2 on a good day. Shame it seems well built !

Good. Well packed product

Installed in the greenhouse. Good pressure (I reduced it using the end screw). Noisy operation.

Very loud - get what you pay for … it was an ok temporary pump … but not suitable for long term use. Camping is supposed to be quiet, calm and relaxing. You should have to worry about waking the wildlife or neighbours up if you want a cup of coffee at 7am

La pompe est super bruyante, j'ai mesurer 50 dB... presque comme ma perceuse!

Great pump. Works great

تم ارسال نوع اخر غير الموجود في الصورة وبدون كرتونة وناقص منه الافيزين وكاب الخرطوم وعند القياس فالمحرك لا يتخطي 0.9 امبير مع العلم ان المكتوب هو انه 6 امبير لكن للامانة هو ممكن يقضي الغرض بس سعره يقل ويتم توضيح بياناته بشكل صحيح

Ich haben mir die Pumpe gekauft das sie selbe schon in Bulli verbaut war jedoch war sie sehr laut, somit habe ich vermutet das sie defekt ist und nochmal das selbe Modell gekauft und siehe da - die neue ist leider genauso Laut. Druck etc. ist in Ordnung aber die Lautstärke ist extrem nervig. Besonders wenn es über die Seitenwand im Bulli übertragen wird trotz dicker dämmung etc.

does not turn off when closing the output valve. the rubber on one leg was missing.
