Reverse Osmosis questions for Indianapolis, IN
What is the water hardness in Indianapolis, IN?
Indianapolis water tests at approximately 17 grains per gallon (GPG). The USGS classifies water above 14 GPG as very hard and above 17.5 GPG as extremely hard — 17 GPG places it in the very hard range, enough to damage water heaters and dishwashers over time.
How long does reverse osmosis installation take in Indianapolis?
A standard reverse osmosis installation in a Indianapolis home typically takes two to four hours on-site. Most homes have accessible utility rooms or basements with existing plumbing stub-outs. From first call to system running water, the average lead time is five to seven days. Installations that require new drain lines or copper re-plumbing take longer but are uncommon for straightforward replacements.
