I have a solar powered setup that takes water from a 1,000 gallon tank that then uses this pump and another to pressurize a small 44 gal pressure tank to then supplies the water for two houses on my property. I wasn't sure this was going to work but knew I didn't want to use an A/C booster pump with an inverter. So this system uses a 12v LifePO4 battery with solar and a standard well pressure switch to kick the pumps on an off. I believe most problems people have with this pump is related to the included pressure switch so I bypassed it and use a standard well switch which is much more robust. I am using this pump in parallel with another smaller Seaflo pump (55 Series 5.5gpm 60psi). This larger pump (53 Series 7.0gpm 60 psi) is strong and is continuing to pump good where the smaller pump is starting to leak and the GPM seems to have reduced. To be fair the larger pump is advertised as "continuous" duty and these pumps are normally used in RV setups that aren't as demanding. I plan to replace the smaller pump with this larger pump and then I will then have two 7.0gpm pumps in parallel which will make this system even better. The two current pumps can usually keep up with all household demands, even multiple showers running while doing laundry. They only struggle if we are doing laundry and then also using multiple hoses around the house to water plants. Just to be clear these are not being used with sprinklers but all other household demands. My sprinkler are running off my well pump system. This system has allowed me to run my well pump less often and also gives me a few hundred gallons of water that can be used even during power outages. Like I said, I wasn't sure this was going to work by two years later and this little pump is still going strong.
