FAQs
Why is a reverse-osmosis (RO) system recommended for homes in Gruetli-Laager?
Many wells and municipal sources in Grundy County show elevated levels of hardness minerals, iron, and trace contaminants such as nitrates and agricultural runoff. A properly sized RO unit filters water down to 0.0001 microns, removing up to 99 % of dissolved solids, heavy metals, chlorine by-products, and unpleasant tastes and odors—delivering cleaner, better-tasting drinking and cooking water no matter what your local source water profile looks like.
How does a reverse-osmosis system work and what will it remove?
An RO system pushes pre-filtered water through a semi-permeable membrane. Only water molecules pass; dissolved salts, lead, arsenic, chromium, fluoride, nitrates, and micro-organisms are flushed to drain. A final carbon post-filter polishes the water before it reaches the faucet. The result is exceptionally pure water with total dissolved solids (TDS) typically reduced to 10–25 ppm, compared with 150–400 ppm in untreated Gruetli-Laager water.
What size RO unit do I need and will it reduce my water pressure?
Most households choose a 50–75 gallon-per-day (GPD) system with a 3–4 gallon storage tank—sufficient for drinking, ice makers, coffee machines, and cooking. Larger families or light commercial applications (restaurants, greenhouses) may upgrade to 200 GPD and a 10 gallon tank. Properly installed, the system feeds its own dedicated faucet and refrigerator line; it does not affect whole-house pressure. Storage tank pressure is 5–7 psi, delivering a steady 0.5–1.0 gpm flow at the RO faucet.
What maintenance is required and can I do it myself?
Plan on changing the pre-sediment and carbon filters every 6–12 months, the membrane every 3–5 years, and sanitizing the tank annually. All cartridges are quarter-turn or quick-connect, so most homeowners can perform service in 20–30 minutes with no special tools. We offer affordable service plans if you prefer professional maintenance; we’ll track filter life, handle disposal, and perform annual TDS testing to ensure peak performance.
How is an RO system integrated into my existing plumbing and will there be any downtime?
Installation takes about two hours. We mount the system under the kitchen sink (or in the basement if space is limited), tee off the cold-water supply with a ⅜-inch feed line, drill a ¼-inch drain saddle into the sink’s waste line, and install a dedicated lead-free faucet in the sink deck. For fridge or ice-maker supply, we run ¼-inch tubing through base cabinets or the basement ceiling. Your household keeps full water service during installation; only the under-sink cold line is shut off temporarily.
What does a professionally installed RO system cost and what warranty do you provide?
A standard 4-stage 75 GPD system installed in Gruetli-Laager typically costs $695–$895, including all labor, fittings, and the first year of filters. High-capacity or remineralization models range from $1,050–$1,350. All systems carry a 5-year warranty on the manifold, tanks, and faucet, plus a 1-year warranty on cartridges and labor. Extended service plans cover parts and labor for up to 10 years and qualify you for annual water-quality testing at no extra charge.
