Quality Build, High Pressure and Reliable
I got this to apply gel to the cabin in case of a wild fire and installed it first for the mister system on the patio, it works great, mists for 6 min then the pump re-pressurizes for 4 sec and mists again, it’s quility built, runs pretty quiet and builds lots of water pressure, just like liven in the city but we’re off the grid with a 12 volt battery. I highly recommend the SEAFO 55-series water pump and accumulator System. I bought a compatible wire connector with alligator battery clip connectors on it, didn’t come with one but it’s still a 5 star product.

Works great and less noise
I had replaced my exiting RV water pump it had a small air chamber but was still very noisy.This new pump was great a lot less noise and it allows for longer breaks in the time the pump turns on and offHighly recommended

Pump Failed & Supplier Not Helpful
The pump with accumulator is a great concept. But the pump failed after about 3 weeks of use. I called the Tech Support phone number provided with the pump and left several messages over a two-day period. I got NO response. The last time I tried the phone number I got a message that it was no longer in service. I got a new number from MarineNow's website and left several messages over the next couple of days and got NO response. I then emailed "adam" at MarineNow per contact instructions. It took 3 days for him to respond but with only "return the pump and we will either fix it or send you a new one". That seemed all good EXCEPT that it had taken over a week to get ANY response. Every phone message that I left (perhaps 7 or 8) described my having this crisis in Mexico and my email again described that I lived in Mexico with the emergency of having no running water due to the pump failure!! I responded to Adam's email again pleading with him to contact me to work with me here in Mexico because I could not just "send it back". It has now been over two weeks with no further response from Adam. I was forced to buy another pump locally. So, I rate the pump a "1" due to its failure in just 3 weeks of use, and I rate MarineNow a "1" because of their lack of technical support in my emergency. I would rate them lower if I could! I even warned Adam that if he did not respond to me that I would post this rating. Apparently he doesn't care!!

Pump for whole house during power outage
Wasn’t sure if this would work or how well at work, but, it’s for use during power outages in our house as I don’t have a 220 V AC generator to run my well pump.It’s in the basement connected to some IBC tote water storage in case of a power outage.The pressure is just like the house pressure. I wasn’t sure if the pump would have enough lift to reach all the way up to the showers but it does. So, if we really wanted to take a shower and the power was out we could.Someone else had to write up on here about using it on an off grid cabin, this is a great fit.We have a fifth wheel RV in this pump is quieter than the factory pump in our 5th wheel.Time will tell if this holds up as other people have noted seems like they have had pressure switch issues, but, that might’ve been on older models.Connector threads are standard pipe thread and you can get adapters to connect to garden hose fittings making this unit portable if I wanted to use in a remote location with no power. Connect it to your car battery or a spare 12 V DC battery and some sort a a water storage tank, IBC totes work well and you have pressurized water wherever you want.
