Review: Great Pressure & Quiet! - The combo pump&tank fit well on my boat. Replaced a 3.5 GPM pump and this one seems to generate better pressure than the last one. It is very quiet and seems to cycle less often.
Review: Great flow and pressure, easy to set up - I've been using this pump for a week to irrigate my garden with reclaimed rainwater. It is easy to mount and connect because of the included hardware and mounting holes in the baseplate. It comes with everything you need to get started, is relatively quiet, includes a good warranty (that I haven't tested), and works well in my application. Great flowrate and pressure.

## Questions & Answers

**Q: Does this product come with the accumulator tank and all the fittings, filter as shown in the photos?**
A: Yes it does, it did for me.

**Q: What size tube and fittings do i need for this system?**
A: 1/2 inch

**Q: Can this handle 24vdc?**
A: Typical rule of thumb is plus or minus 10% on any voltage, AC or DC and from 12 volts to 240 volts plus. So that being said the 12 volt DC pump should operate safely with a power (voltage) source of 10.5 to 13.5 volts DC, so you 24 volts DC would MOST CERTAINLY cause serious damage to the pump motor. Insco Electric  makes it Buck and Boost transformer for less than $10.00 that would be a safe and inexpensive fix, or you could use a Diode, witch would be more difficult to incorporate one into a safe enclosure and power connection. Good Luck

**Q: Is there a version of this that runs on regular 110?**
A: Yes, you can get 110 volt pumps with accumulator to do the same thing on 110 power.  Here is an example on Amazon:
