Following the RCC7U is the iSpring RCC1UP which is an upgrade to the RCC7U model with the addition of a booster pump. It’s a unit that guarantees maximum performance and great filtration results in situations where the pressure of the source water is quite low.
The RCC1UP utilizes a 6-stage RO filtration process same as the RCC7U. The first three pre-filters comprises of a sediment filter, a carbon KDF (GAC) filter and a carbon block (CTO) filter.
These filters effectively eliminate all large contaminants as well as chlorine, chloramines and other chemicals in the water. The RO membrane, on the other hand, performs a thorough filtration removing up to 99% of the remaining contaminants down to 0.0001 microns.
The fine GAC filter in the 5th stage takes care of residual contaminants from the RO tank while the 6th stage UV sterilizer which consists of powerful 11 watt UV lamp destroys all the bacteria, viruses and other microorganisms that may have made it past the RO filter.
This highly effective filtration process ensures the water delivered on the RO faucet is totally free of contaminants and very safe to drink and cooking.
The unit is also equipped with a flow sensor switch that automatically controls the turning on and off of the UV light according to the water flow hence saving power.
Pre-installed Booster Pump
Besides featuring a UV light filter, the RCC1UP has a pre-installed booster pump which is an essential addition that allows the system to work efficiently even when the source water pressure below 40 psi.
The pump can raise the pressure of the feed water from as low as 30 psi to around 80 psi which is an optimal pressure level that enhances the performance of the unit and its production speed too.
Therefore, unlike its predecessor the RCC7U, this unit will give you faster tank fill rates even with fluctuations in your source water pressure.
Another area we liked about this iSpring model is its high capacity RO membrane which can output up to 100 gallons of water per day.
This is much higher capacity than most of the other standard residential RO systems from iSpring on our list. It’s sufficient output that can suit well families of almost any size.
Furthermore, with the pump boosting the production speed, you can expect a steady flow of clean water all day long. The pump also reduces the wastewater from 3 gallons to about 2 gallons for every gallon of purified water produced which is way much better.
Installation and Maintenance
We found the RCC1UP relatively easy to set up as it uses push to connect fittings and comes with a clear manual and all the parts you need to install it.
It might be a little tricky though if you are not that good with DIY installations as it will require a power source and a bit more space because it’s somewhat bulky. However, it will fit in most under-sink kitchen cabinets provided is higher than 20”.
The filter cartridges in the first 3 stages require replacing every 3 to 6 months based on your water quality while the stage 5 filter is to be replaced every year. The UV light filter can last about a year.
The RO membrane requires the least maintenance since it can last 2 to 2 years before requiring replacement.
The best part is that despite having the boost pump, the system runs quietly, only producing a low volume hum which is hard to hear with normal kitchen activity.
The overall quality of the unit is good too. The prefilters feature thick and solid housings while the fittings are plastic but feel durable. It’s a system that will definitely serve you for many years.
Aside from the installation being slightly tricky, the RCC1UP is a powerful and reliable RO system that’s designed to get the job done right.
