12 Volt Diaphragm Pump 3LPM 0.8 GPM 100PSI Self Priming Sprayer Pump 12V DC Fresh Water Pump Water Pressure Switch for RV Camper Marine Boat Lawn (30W)

Arrived on time, was packaged well, works very good, a lot of pressure and high flow rate. Direct replacement for the one I had that failed. Good quay. Would buy again.

Easy to install, great pressure. Works great, and it’s pretty small and will fit inside compact areas.thus pump function awesome. Very durable.

Good pump that does what it should but boy is it loud! It's mounted in a cupboard under the sink in a motorhome so maybe there's some echo but I would still classify it as very loud. That's the negative but on the positive side the pump works really well. It provides plenty of output for a Class C motorhome of average size and length. The pressure in the shower is just fine. As a bonus for anyone who does a lot of dry camping, it uses less power and water than the original pump but achieves the same goal of getting the water from the fresh tank to the tap.

Update: The pump started leaking where the diaphragm meets the motor. No amount of tightening the screws stopped the leaking. Shortly after that the pump let out the magic smoke and burned up. Reduced the rating to 1 star. Disappointed. So this is fairly impressive so far. It was securely packaged. When I opened it I was happy to see several accessories with the pump. It comes with two 1/2" threaded to 3/8" barb fittings, two rubber o-rings, two hose clamps, and the electrical connector to wire it up. Seems well made. Specs are listed in SAE units which, until America adopts the metric system, is very convenient. Even the box is free from spelling errors. Pretty good work for a low cost Chinese product. Im happy so far. Will update when I install it. Update: installed pump, followed directions on the box for the most part, and everything worked fine. I have it rigged to a fairly sensitive float switch in a turbulent bucket. So the duty cycle is extremely short, like 1 second, but very consistent. I would say it kicks on every 10 seconds, for 1 second. Maybe even more often. This will really be a good test of the durability of this pump. Will update after a few months.

Update: dated 5th May 2024 I purchased three pumps as follows: March 2020, September 2023 and November 2023. The one that I purchased in 2020 is still functioning like a boss while, unfortunately those purchased in 2023 have stopped functioning. CUSTOMER SERVICE WAS GREAT, THEY IMMEDIATELY REFUNDED. I will purchase the pump again. My house is a two storied structure. Because of low water pressure on a regular basis I utilize water tanks and pump water upstairs using AC pumps to the faucets in my house. Not long ago both AC pumps started giving trouble so I decided to experiment with this DC pump since I already had the batteries in preparation to setting up a solar system. Quite naturally the water pressure is not the same as the AC pumps, however, the water flow to the shower head is sufficient to have a comfortable shower. NB: Two showers cannot be operated together. If thee is a power failure from the Grid my life continue to move along because I now have an uninterrupted water supply. I highly recommend these pumps for use similar to mine. Today I will connect an additional pump to the system and monitor the water flow to the shower upstairs.

Great product so far but not sure on the longevity Though (Ill update my review for sure). I ordered the 1/2” screw I/o. It came with the 2-1/2” brass adapter to 3/8” barb (standard pex), silicone washer, two clamps, and a dual wire connector. Packaged really well and so inexpensive compared to anything with similar specs in Amazon. I just needed a portable syphon to drain my indoor kratky hydroponic pvc post pipe setup. I’ve been using pump type syphon that sometimes leak or hose come off and spill all over. Since this will be seasonal, I plan to make a diy cloner/sprouting machine using this pump for recirculating mister. Pump is tolerably noisy for what I need it for but yes for additional $50 more you can get a super quiet one maybe. Quality looks good too for the price, so it deserves a 5 star. If it last a year, I will be more than happy to buy another one. I used a 3/8"ID clear hose and worked very well. I also installed a switch in it foot which I attached using heat glue gun.

Purchased the 108PSI version. So far as a pump - the little I used it, it performed well. Was able to pull the water in from the tank located about 40 feet away. Plenty of pressure. In fact, too much pressure. I intended to use this for a misting system I have to boost the efficiency of my AC condenser. The buffer tank I use has an emergency pressure release valve that kicks in at 125PSI. This pump (supposedly set for 108PSI) was triggering this. The cutoff switch does work if I dead-head the line - it's just that the operating pressure is much higher than the value in the description. Unfortunately, with the removal of the adjustment screw, I cannot correct the problem so this goes into my "Someday I'll find a use for this" pile.

Replacent for a weed tank sprayer.
