## 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:

## Customer Reviews

### ⭐⭐⭐⭐⭐ 10/10 best upgrade for an RV
*by  on Reviewed in the United States March 4, 2023*

**TLDR five stars and a super straightforward and worthwhile upgrade in the RV! **Water flow is smooth and plentiful (like a house). The pump is so quiet I have to check if I actually turned it on! The flow rate seems to be really good, we have a standard low flow shower head in the RV and it acts just like the shower at the house. It’s on a rubber isolated backing plate and the pump and accumulator are also isolated from the backing plate via rubber feet. It’s got a neat set of power and ground leads in the top corner for quick access and connections. It does not show it in the pin it’s but comes with a strainer for the inlet side and two right angle hose adapters. It took me longer to get the access panel out of the way and find the correct bit to undo the RV screws then swapping out the pump. Would highly recommend this to anyone that’s tired of the shuttering water and loud noise a normal RV water pump is.

### ⭐⭐⭐⭐⭐ Consistent flow of water to run my tankless water heater in our camper.
*by  on Reviewed in the United States July 11, 2026*

Quieter than the Surflo water pump that was OEM to my camper. The flow of water is now a consistent flow instead of changing rate of flow. My tankless water heater runs better with this new pump with accumulator installed. I can get 2 hot showers before emptying my freshwater tank. This is my backup for when my city water hookup has too low of pressure for the water heater to work properly.

### ⭐⭐⭐⭐⭐ Great all in one solution for your water system
*by  on Reviewed in the United States July 6, 2025*

This pump accumulator combo was a perfect solution for my van. Easy to wire and plumb into my system.
