Our take
The SpringWell Whole House RO (Ultra) is a strong fit for severe contamination / problem wells. As with any whole-house treatment decision, the right choice depends on your incoming water (hardness, chlorine vs. chloramine, any flagged contaminants) and the size of your home. If you haven't already, check your local water-quality data before committing.
What problem does it solve?
Strips dissolved solids - PFAS, lead, nitrate, arsenic, sodium, fluoride - from every tap in the home via reverse osmosis, not just the kitchen sink. Includes a remineralization stage so the finished water is not flat or aggressive on copper pipes.
Who is this for?
Homes with multiple contaminants of concern that a carbon or softener cannot handle, properties on poor-quality city or well water, and anyone who wants RO-quality water at every tap rather than at one under-sink faucet. Requires drain access and re-pressurization.
Pros
- Removes PFAS, lead, nitrate, arsenic, sodium, fluoride at every tap
- Includes remineralization stage so finished water is not flat
- Solves contamination problems carbon and softeners cannot
- Whole-house RO water, not just at the kitchen sink
- Designed for difficult well or city water
Cons
- Expensive upfront and to maintain
- Requires drain and electric re-pressurization pump
- Wastes 1 to 2 gallons per gallon produced
- Almost always needs a plumber to install
- Overkill if your only issue is chlorine or hardness
Can I install this myself?
Plumber recommended
A whole-house RO is the most complex residential install in this category. You need feed, drain, a storage tank, and a re-pressurization pump to push the finished RO water back into the house. Almost all owners hire a plumber familiar with RO systems. Budget $1,500 to $3,500 for professional install, separate from the equipment cost.
What are the running costs I should foresee?
Membrane replacement every 2 to 3 years, pre/post filters every 6 to 12 months, plus electricity for the pressure pump. Realistic budget is $300 to $600 per year. RO also wastes 1 to 2 gallons of reject water per gallon of finished water, so factor in water-bill impact.
Frequently asked questions
+Who is whole-house RO for?
Homes with multiple contaminants of concern that a carbon or softener cannot handle: PFAS, lead, arsenic, nitrate, or high TDS. Also for anyone who wants RO-quality water at every tap rather than at one under-sink faucet.
+Can I install this myself?
Realistically, no. You need drain access, electrical for the pump, a storage tank with proper pressure regulation, and re-pressurization plumbing back to the home. Budget $1,500 to $3,500 for a plumber experienced with RO.
+What are the running costs?
Plan on $300 to $600 per year between pre/post filters, periodic membrane replacement, electricity, and 1 to 2 gallons of reject water per gallon produced. It is the most expensive option in this category to run.
+How is it different from an under-sink RO?
Under-sink RO treats one faucet for drinking and cooking. Whole-house RO treats every tap, every shower, every appliance. Choose under-sink unless your water-quality report shows contaminants you do not want touching your skin or laundry.
+Will it remove hardness too?
Yes; RO removes calcium and magnesium along with everything else dissolved. In most installs SpringWell recommends a softener upstream to protect the membrane and extend its life.
