If so do I need a pressure regulator?** A: It has a limit pressure switch set at 45PSI. We use a regulator to slow the flow. **Q: does this pump accept standard garden hose connectors?Tks** A: no, but you can buy adapter or do what I did and cut an old hose and slid over the pumps fitting with a clamp. Worked great. **Q: Can this pump run for an extended period of time? 1-2 hours?** A: Been using these for years on my water filtration system... I run it for 20-30 minutes at a time with a 15 minute break. The pump gets EXTREMELY HOT after this amount of time, so I always have a small fan blowing on it when in use. I have to replace the pump every 1-2 years as well. Be careful with the plastic part where the hose screws on... it breaks very easily , especially after months/years of use. Besides that it works well enough that I keep coming back for it! **Q: Whats the max temperature this can pump** A: The maximum temperature this pump can handle is 140° F. Any higher than that and the internals of the pump can be damaged over time. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quiet, and easy to install *by M***T on March 7, 2026* This is a great pump for our food trailer. It is small, and still provides good water flow with little noise. It was simple to install, and seems like it will be very durable. It primed the system quickly and just works great. I recommend it. ### ⭐⭐⭐⭐⭐ That the pump is working. *by C***K on April 1, 2026* Love the Seaflo 33 pump, don’t need nothing else. Works powerful. ### ⭐⭐⭐⭐⭐ Using as a camp shower pump *by M***Y on July 17, 2019* I am not a plumber, but consider myself pretty handy. This is the 4th and final pump I got from Amazon as part of the camp shower build process (NOT defective, just trying different options). Here's what I learned, hopefully this will be helpful to others who are building outdoor camping showers. 1. The pumps plastic male fittings don't match box store brass fittings. They likely won't leak in plastic-on-plastic installations, but if you're screwing a metal female fitting onto the pump's plastic male fittings, they won't fit and will leak, even though technically both will say 1/2". I used flexible 1/2" hose and some hose clamps to make it work and avoid brass to plastic fittings. 2. This is an on-demand pump. You plug it in, and it will sense if water is being requested anywhere in your system and start pumping. Plan to build a system that's as leak-free as possible or this pump will continue to cycle periodically. I built a prototype garden hose system, which was full of leaks, and this pump kicked on for a second every 15-20 seconds because it assumed I was requesting water (even though it was just leaks). If your system is leak-free, the pump will stay off and silent until you open a valve somewhere in the system. 3. I bit the bullet and bought the $70 PEX crimp tool, which greatly simplified building my shower system. You'll need the crimp tool, some metal ring clamps, and a few baggies of elbows, tees, splicers, and shut-off valves. I was able to build my system with zero leaks. If you're doing this, get white PEX 1/2" line, it can be used for hot/cold/any water, in other words, blue cold line, red hot line, and white neutral line are all identical and differ only cosmetically. Don't think you need to buy red line to run hot water, there's nothing inherently special about color lines - they are all the same, and the only reason they are colored is to tell them apart. 4. The pump is not silent and will vibrate, which means you'll need to attach it to some kind of a solid substrate very firmly. Mine is outside and the noise is not a problem, but if you're doing an RV/interior build, you'll definitely hear it kick on and work, especially if it's bolted to a hollow surface, like under the stairs. Find a way to bolt it to a cinder block or an anvil to dampen the vibration. 5. My system includes a shower and a sink for washing hands (same line, split via a T connector), and this pump is pretty amazing at supplying strong pressure across 10-15 yards through 1/2" PEX lines. You'll be able to take on-demand showers with serious pressure. My wife is still freaking out about the awesomeness of taking pressurized showers in the middle of nowhere. Apparently, gravity/solar showers are huge bummers with ladies who wish to wash their hair, who knew. Overall, if you also grab some flexible reinforced tubing with clamps to bypass brass-to-plastic size fitting size issue, you'll be able to build whatever you need. Strongly recommend. ## Frequently Bought Together - SEAFLO 33-Series Water Pressure Pump - 115V AC, 3.3 GPM, 45 PSI, Self Priming, Smart Pressure Switch, UL & CSA Certified, for RV, Caravan, Off-Grid, Marine, and Industrial Use - SEAFLO Accumulator Tank Water Pump Flow Control with Internal Bladder - 125 PSI, 23.5 oz (0.75 L) | Reduces Pump Cycling and Smooths Water Flow for Marine, RV, and Off-Grid Systems - BOSCH Electric Mini-Tank Water Heater Tronic 3000 T 4-Gallon (ES4) - Eliminate Time for Hot Water - Shelf, Wall or Floor Mounted --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/49370447-seaflo-33-series-110v-115v-ac-fresh-water-pump-3](https://www.desertcart.us/products/49370447-seaflo-33-series-110v-115v-ac-fresh-water-pump-3) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-22*
