iSpring RCC7P 5-Stage Reverse Osmosis System Review

iSpring RCC7P reverse osmosis system is an extended version of the RCC7 with an electric booster pump that ensures reliable, consistent performance regardless of pressure variations. This RO system is ideal for low-pressure water, the booster pump allows the system to achieve tank fill up to 50% faster and 50% less water waste.

If you live in an area where your typical residential water pressure is low, say around 40psi or lower, then this iSpring RCC7P might just be the ideal choice for you.

It’s a high-performance system designed with an inbuilt pump that boosts the feed water pressure high enough to allow the system to perform much effectively.

Filtration Process

Like the RCC7 model, the iSpring RCC7P utilizes a 5-stage RO filtration process which ensures reliable and efficient water purification results.

The three first stages consist of three 5-micron pre-filters that include a polypropylene sediment filter followed by a carbon KDF (GAC) filter and then a carbon block (CTO) filter.

The first two filters trap all sediments, large contaminants, and microorganisms that are bigger than 5 microns including chlorine, chloramines and other chemicals.

Smaller contaminants, chlorine, and microorganisms that pass through the second stage are further removed by the carbon block filter in the third stage.

The fourth stage is a high rejection RO membrane which gets rids of all remaining contaminants that are as small as 0.0001 microns.

It has a rejection rate of 99.99% hence can eliminate more than a thousand harmful pollutants including arsenic, viruses, bacteria, chemicals, lead, pesticides, chlorine, and fluoride.

The final stage is the fine GAC filter that provides the final polishing. It removes any possible residual contaminant and odor that may have accumulated in the RO tank delivering clean and safe purified water to the faucet.

Inbuilt Booster Pump

Now the most commendable thing about this iSpring RCC7P model and what makes it really perform so well is the fact that it’s equipped with an inbuilt booster pump.

The RO filtration process requires high feed pressure so as to force all the impurities out of your water and when it’s low, the system will not be efficient. This is where this booster pump comes into play.

It’s designed to raise the inlet/feed water pressure going into the system from as low as 30 psi to about 70 to 80 psi which is an ideal level that optimizes the performance of the system from the first stage to the final one thereby facilitating more efficient filtering.

Furthermore, the pump features multiple sensors which help keep track of the pressure and turn on the pump as soon as the source water pressure falls below around 40 psi.

The sensors also automatically turn off the pump when the ideal pressure is obtained hence preventing any chances of overheating or other potential damages. Therefore, you are assured of consistent performance regardless of pressure variations.

Filtration Capacity

The RCC7P like its counterpart above utilizes a high capacity RO membrane that’s capable of producing 75 gallons of water per day which is large enough to handle the needs of most medium to large families.

Moreover, the booster pump helps increase the water production speed of the system allowing it to achieve almost 50% faster tank fill rate compared to its competitors.

Boosting the water pressure also has the effect of minimizing wastewater production as the pump forces more water through the filters there reducing the wastewater production to up to 50% which is quite commendable.

Installation and Maintenance

In terms of installation, the unit is designed for DIY installation with color-coded tubings and a push to connect fittings. It’s a pretty simple process that may not require the assistance of a professional if you some little technical skills.

The user manual is clear and well-written, and all the necessary parts and tools required for installation are included plus a video should you need visual instructions.

You will need to change the pre-filters after every 6 months while the post-carbon filter can last up to a year before needing to be replaced and the RO membrane can go for at least 2 years.

Both the pump and the system are quiet during operation hence you can expect no disturbance at all. They produce very little noise which you can hardly hear over normal kitchen activity.

In general, there’s no notable setback in this iSpring RO system that can cause any alarm. It’s a reliable unit that will deliver great performance especially in situations where the feed water pressure is below 40 psi. All the parts are of good quality and certified by FDA and WQA.


  • Optimum RO filtration performance through 5 stages
  • Booster pump effectively raises water pressure to ideal levels
  • Has a high pure water production rate with fairly less wastewater
  • Easy to install with all the necessary tools included
  • Both the pump and RO unit operate quietly
  • Ideal for use in areas with a feed water pressure of less 40psi
  • Backed by a 1-year warranty with lifetime support


  • The supply water valve and O-rings are not of the best quality
  • Requires a power source which may limit your installation options

Installation Guide

This video shows you step-to-step how to install iSpring 5-Stage RCC7P Reverse Osmosis System.



Does the pump help in supplying stronger water flow out of the faucet?

No, it doesn’t, the pump is used for creating more pressure at the water inlet, not at the outlet or storage tank.

Does this RO system remove Pfas/Pfos?

The RO system has not been certified in removing this contaminant but it will remove many contaminants.

Does the pump run constantly or periodically?

Periodically, only when the pressure in the storage tank drops and the auto-shutoff valve opens.

Can I use the pump to pull water from a source like a barrel?

The pump is designed not for pull water from a source but only to create more pressure at the inlet of the RO system.

What is the pump electric cord length?

It is about 3.5 feet.
