Water treatment questions I get asked most
I'm Trent, the owner-operator of Palouse Water Pros in Moscow, Idaho. These are the questions I hear most from homeowners around Latah County — on wells and on city water — answered as plainly as I can. If yours isn't here, call or text and ask me directly.
Getting started
How do I get in touch, and what does the first conversation cover?
Call me at (208) 883-4444, text (949) 456-6889, or email info@palousewaterpros.com — whichever is easier. The first conversation is short: what you're seeing, whether you're on a well or city water, any equipment you already have, and any past test results. From there we set up an on-site visit.
Do you work on well water and city water?
Yes — both. Most of the challenging work on the Palouse is well water, especially high iron and manganese, but I also treat city water in Moscow for hardness, chlorine taste, and drinking water.
How do I know if I have hard water or other water problems?
Common signs include spots on dishes, dry skin and hair, scale on fixtures and appliances, staining, or an unpleasant taste or smell. The 2-minute water quiz can help you narrow down your symptoms, and I test your water on-site during the visit.
Do you offer water testing, and what happens at the on-site visit?
Yes. I do high-quality water testing on-site, right in front of you, so you see the numbers as they come up. A visit usually runs 45 to 75 minutes: I test the water, look at your plumbing and the space where equipment would go, and listen to what's bothering you. For standard jobs we can often talk through options during the visit. For challenging water I may ask a few follow-up questions or have you note some simple observations before I recommend anything. More on the water testing page.
Do I need a lab test?
Not always. On-site testing covers the numbers that drive most treatment decisions — hardness, iron, manganese, pH, and more. Lab testing is worth it when the situation calls for it: bacteria such as coliform, or anything unusual. If you've only ever had a basic realtor's or lender's test at closing, you likely don't have manganese, pH, or tannin numbers at all, and those matter here. See how to read a well water test.
What area do you serve?
I'm based in Moscow and serve Latah County and the Idaho side of the Palouse. Regular stops include Moscow and Viola, Troy, Deary, and Bovill, Genesee, Kendrick and Juliaetta, and Princeton, Potlatch, and Harvard. Not sure if you're in range? Text me your address and I'll tell you straight.
Cost and timeline
How does pricing work?
It depends on your water. I don't quote a system before I've tested, because the right equipment for one well can be the wrong equipment for the house a mile away. After the visit I recommend the best solution (or a couple of options when that makes sense) and send a clear written proposal. There's no pressure to decide on the spot. My goal is never too much and never too little — I'd rather recommend less equipment than more, and sometimes the answer is that you need less than you feared.
How long does the process usually take?
Every job is different, so I give you an honest timeline for your specific situation after the site visit. Complex water or lab testing can add time — I'd rather tell you that up front than surprise you later. Once you accept the proposal, I build your equipment and install it myself, and I'll update you if anything shifts.
Well water
Why do Palouse wells run high in iron and manganese, and what's the difference between them?
Most rural wells here draw from fractured basalt or the sediments between basalt flows. That groundwater is low in oxygen, so iron and manganese dissolve out of the rock and stay invisible until the water meets air. Iron shows up as orange-red staining and a metallic taste; it starts staining around 0.3 mg/L. Manganese leaves black or dark-brown slime and gray stains, starts staining as low as 0.05 mg/L, and at 0.3 mg/L is in EPA health-advisory territory. Manganese is also harder to remove, which is why many "iron filters" leave black staining behind. More on my iron and manganese removal page and in the Palouse well water guide.
My well tested positive for coliform. What now?
Any positive coliform result matters. It usually means surface water is finding a path into the well, and it's common on older wells, shallow casings, and after wet springs. Sometimes the fix is at the wellhead; sometimes continuous disinfection is warranted. Either way it changes the rest of the treatment design, so it needs to be accounted for from the start rather than bolted on later. Step by step: what to do after a positive coliform test.
Why does my water smell like rotten eggs?
That smell is usually hydrogen sulfide. The first thing I check is whether it shows up on the hot side only or on both hot and cold — hot-only often points to the water heater, while both usually means it's coming from the well. Where it comes from changes the fix. See my sulfur smell page for more.
What are tannins, and why do they matter?
Tannins are organic material that can tint water a tea color that doesn't settle out. They can bind iron in ways that make standard iron filters underperform, and they're a frequent reason a previous system never really worked. Wells up the Highway 6 corridor tend to run heavier on tannins and manganese than wells closer to Moscow.
Will one filter fix everything?
Sometimes one piece of equipment really is the answer — a properly configured softener can often handle moderate dissolved iron, manganese, and hardness in one pass. But heavier iron, coliform, tannins, or pH outside roughly 6.8 to 8 can each call for another stage, in the right order. There's no single best filter; there's a best design for your well's numbers.
City water
Is Moscow city water hard?
Moscow's water comes from city wells drawing on two basalt aquifers, the Grande Ronde and the Wanapum, and it is treated with chlorine before distribution. USGS has described the area's groundwater as moderately hard. The City also notes its water carries iron and manganese that can react with chlorine and form reddish sediment, which is part of why it flushes its system. The City publishes an annual water quality report, and I test at your tap during the visit. More on my Moscow city water page.
Does a softener make sense on city water?
It can. It depends on the hardness at your tap and what you want to fix — scale on fixtures and water heaters, spotted dishes, dry skin and hair. I test first and tell you honestly whether a softener is worth it for your home. See my water softener page.
How do I get rid of the chlorine taste?
Activated carbon is the usual tool for chlorine taste and odor. It can be a whole-house stage or part of a drinking water system, depending on whether the taste only bothers you at the kitchen tap or everywhere.
Is reverse osmosis worth it?
For drinking and cooking water, an under-sink reverse osmosis system tailored to your water is one of the best upgrades you can make. It isn't a whole-house fix, and on hard or iron-heavy water the membrane needs the right pretreatment to last. See my reverse osmosis page.
Equipment
What's the difference between you and the bigger water companies?
I focus on thoughtful system design, clean installations, and honest recommendations tailored to your specific situation and budget. I'm an owner-operator: I test your water, design the system, and install it myself. My approach is low-pressure and personal.
Do I need a whole-house system or just drinking water?
It depends on your goals. Staining, scale, and odor throughout the house call for whole-house treatment; if the main concern is what you drink and cook with, a drinking water system may be enough. I'll walk you through practical options so you can choose what makes the most sense.
Salt-based softener or salt-free — and what about magnetic descalers?
A properly configured salt-based softener actually removes hardness, and on Palouse well water it can often take out dissolved iron and manganese too. Salt-free "conditioners" sold as softener alternatives don't deliver what the marketing implies on genuinely hard water with iron present. Magnetic and electronic descalers have no credible evidence behind them on water like ours, so I don't sell them. Which salt to use is covered in the softener salt guide.
Do you use proprietary equipment?
No. Everything I install uses industry-standard, serviceable components — standard valves and media that any competent tech can service years from now. You're never locked into one company.
Can you service a system someone else installed?
Often, yes — it depends on the equipment. Call and describe what you have, and a photo of the valve and any labels helps.
Can I have a softener and reverse osmosis together?
Yes, and they work well together. The softener handles hardness for the whole house and protects the RO membrane from scale, and the RO system gives you drinking and cooking water at the kitchen sink. I size and place them as one design.
What if I'm building a new home?
Bring me in early. I enjoy helping plan the water system properly on new builds and remodels, including water quality at every fixture and the utility space, so the equipment has room and you start with good water from day one. See planning water treatment for a new build.
