## Questions & Answers

**Q: Where can the pump be installed?**
A: Great for use in kitchen and bathroom. It is also the great partner of camper, sprayer, garden sprinklers, fertilizers, sprinkler faucet and agricultural irrigation as you like.

**Q: Can this pump have a nozzle connected to it and be used as a “on demand” pump?**
A: This pump turns on when you plug it in, so if you connect a hose or tube to the pump with a valve on it, it will stay primed. So when you open the valve it will pump.   I don't believe it has a pressure valve that turns the motor off!   So if it's always running, it might fail faster.   I'd recommend using some sort of pressure valve that can sense pressure and turn on or off depending on pressure.

**Q: Is this pump rated for continuous duty?**
A: Continuous use will overheat, it is best to let it rest.

**Q: Is there a minimum outflow rate the pump can operate at? Would thai be suitable for a single outlet RO filtration system from an unpressurized tank?**
A: Ok, here's the fact. My bucket to do list is huge. The install of the pump we're talking of I don't have it in yet. But to your question I've read up on the pump and yes since the flow rate is adjustable by a "set" screw it just goes to reason that you can set it to the minimum as well as to the maximum with out causing another issue. The case in point with me is the galley faucet, not a one of us has found the reason, why is the hot water flow so drastically low than the cold water flow. When we turned on the cold water it flows very good, with the switching to the hot water, (it's a single control faucet) the hot water is just a trickle. So we figured if this pump is installed between the hot water supply line and the faucet it will bring the issue to an end. I'll close this with in my career decision I became what's known as a computer systems analyst so if I drop the word computer and have left systems analyst I become able to problem solve matters such as plumbing, electric not so much so, but yet skilled enough to solve the "things" that can be so annoying that it gets our goat.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Gets the job done
*by R***. on June 6, 2023*

In a world of negativety its nice to read something positive let alone receive a decent product. As u can see I have this pump temporarily hooked up to 1 of my rain water containers. I will eventually T both of them together so it can draw from both but as of right now this little pump gets the job done. I have 31 drip spikes running off of just this pump and I have no pressure loss from front to end. Also the built in screen is nice as it collects alot of crud from my rain container that normally would clog my drip spikes. I've also used this pump for a sprinkler with no issues. I also like the auto shut off at 40psi so I can set a timer on my line. The pump does get considerably warm and I've only had it for couple months now which concerns me for it's longevity but we'll see. I think it's a decent little pump and if it keeps chugging along for some time then my money was well spent. So there ya go, something positive and nothing like a real review with real world working conditions put to it

### ⭐⭐⭐⭐⭐ A nice powerful pump for my cabin
*by B***E on March 25, 2022*

I really like this Dreyoo pump, over the past 20 years I have used Shurflo 120V 3.2 GPM and 12V 3GPM pumps for my cabin's water tanks. They provided enough water for doing 1 thing at a time. Problem is when someone is showering and a toilet gets flushed the shower turns into a dribble because the toilet has no water restrictor like a shower head and the water flow goes mainly to the toilet fill valve.Well this Dreyoo solves that problem because it flows more vs the Shurflo, approx. 4.0GPM. While taking a shower now the flow is reduced but still plenty for showering. When I spray my plants or wash my windows with a spray nozzle the water stream goes out over 20 feet now vs the Shurflo's 10 feet. It is a more powerful pump with more flow and pressure than the Shurflo. It's a bit quieter, maybe 10% better.Now we will see if it last's as long as my Shurflo's have. I liked my Shurflo's but hope this is even better.

### ⭐⭐⭐⭐⭐ Great Demand Pump
*by D***  on April 24, 2025*

I love this pump, I have it mounted on my 2 300gallon water tanks for watering my gardens. This will be the fourth year and I have never had a problem. Well worth the money I paid for it.
