Clear answers.
For everyday water.
What’s in your glass? What’s building up in your shower? What should that filter be doing? Start with a straight answer, then explore the guide that fits your home.
These answers help you ask the right questions. A water test, the right laboratory results and your equipment’s own manual help decide the next step for your home.
Understand your water
Start with your supply and what a test can actually tell you.
If my water looks clear, is it safe to drink?
Clear water is not proof of safety. Some well-water contaminants have no noticeable taste, smell or colour. Use the appropriate laboratory tests and follow public-health advice rather than judging by appearance.

Do Halifax and Dartmouth homes on municipal water need a filter?
Not automatically. Health Canada says a community supply meeting Canadian drinking-water guidelines usually does not need extra treatment for health reasons. A taste preference is a separate question. Check your supplier’s information before choosing a device.

When should I test my private well water?
Keep a regular bacteria and chemistry testing plan. Ask your laboratory or public-health team which tests and timing fit your well, especially after a change, repair or unusual result. Use the province’s current guidance and the lab’s sampling instructions.

Is ECW’s in-home water test the same as a laboratory test?
No. The ECW visit discusses your concerns, explains the checks being performed and includes a treatment demonstration. It is not a laboratory safety certification. Ask what is included; use a laboratory for the bacteria or chemical tests your situation needs.

Does a TDS reading tell me whether water is safe?
No. Total dissolved solids describes dissolved material in a sample; a handheld meter estimates it from conductivity. That single number does not identify individual contaminants or replace bacteria and chemistry tests.

Compare the treatment options
Choose for a specific need. Different systems do different jobs.
What is the difference between a water softener and a filter?
A conventional ion-exchange softener reduces calcium and magnesium hardness. A filter is chosen for particular substances or particles. Neither name means that the system treats every possible water concern.

Does reverse osmosis remove everything from drinking water?
No treatment should be assumed to remove everything. Reverse osmosis uses a membrane and may include other filters. Check the exact model’s certified reduction claims and maintenance requirements against your water results.

Will UV treatment soften my well water?
No. UV treatment addresses microbes within a system’s specified conditions; it does not remove hardness minerals. Softening and UV disinfection solve different problems. Ask what each part of a proposed system is intended to do.

Will a shower filter fix hard water and scale?
Do not assume so. NSF/ANSI 177 certification concerns chlorine reduction, not hardness removal. If scale is the concern, measure hardness and compare the appropriate treatment rather than relying on the words “shower filter.”

What is the best water treatment system for a Nova Scotia home?
There is no single best system for every home. Start with your supply, relevant test results, household goals and a model’s verified claims. Ask about installation, replacement parts, upkeep and total running costs before deciding.

Make sense of a change
A useful observation starts the investigation. It does not diagnose the cause.
What causes white buildup on taps and showerheads?
Mineral scale can be associated with hard water, which contains dissolved calcium and magnesium. Appearance alone does not measure hardness. Check a result from your property before deciding how to treat it.

Why does my water smell earthy, musty or like rotten eggs?
The cause depends on the supply and where the smell occurs. Halifax Water explains that geosmin can cause an earthy taste or smell in some supplies; that does not explain every odour. Note whether it affects hot water, cold water or both, and contact your supplier or a qualified water professional.
Read the source: Halifax Water — My water has a taste and odour
What should I do if the taste or colour of my water changes?
Check your supplier’s current notices, or seek testing advice for a private well. Note when the change started and which taps are affected. Do not use taste or appearance to decide that water is safe. Follow any drinking-water advisory.

Could a water filter cause slower flow at a tap?
A clogged filter can restrict flow, but low flow can have other causes. Note whether one treated tap or the whole house is affected. Check the model’s service instructions and have the cause assessed rather than assuming a new cartridge will fix it.

Care for equipment you already have
Use the model number and its manual. Skip the guesswork.
How often should I change my water filter?
Use the interval for the exact cartridge and system. A service cycle may depend on time or the amount of water treated. Follow the manufacturer’s replacement schedule even if the water still looks or tastes normal.
Filter maintenance questions →
Read the source: NSF — Changing water filters
Can I use any cartridge that fits the filter housing?
No. Similar size does not prove that a replacement seals correctly or provides the same performance. Use the correct specified cartridge and check its verified claims. Keep the system model and cartridge part number with your service records.

Why does my water softener run a regeneration cycle?
Regeneration restores the softener’s ability to exchange hardness minerals. The timing and water use depend on the model and settings. Use its manual or service provider to confirm the expected cycle; there is no universal schedule for every softener.

Why is my softener running at a different time after a power outage?
Some controllers need their clock checked after a long interruption. Clock memory differs by model. Follow your exact manual for checking the time; do not copy another softener’s settings. The linked manufacturer example is not a claim about the model in your home.

Is water in the salt tank or water going to the drain always a fault?
The model and stage of its cycle matter. A short description cannot establish whether the amount or duration is normal. If water rises unexpectedly, overflows or keeps discharging beyond the documented cycle, contact the equipment service provider. Do not change drain routing or bypass settings by guesswork.
Should I reset a flashing service light or alarm?
First identify the equipment, model and exact message, then check its manual. A reminder and a fault are different. Do not assume a reset fixes the cause or proves the water is safe. Contact the equipment service provider if the meaning is unclear.
Choose the next step
Know who to contact and what happens after a request.
What should I do about a leaking under-sink filter or RO system?
An active leak needs prompt attention. Keep clear of wet electrical equipment and contact the equipment service provider or a qualified plumber. Do not wait for a demonstration visit to deal with damage. Avoid opening a pressurized housing or guessing at valves.

Can I request a water treatment visit in Dartmouth, Halifax or elsewhere in Nova Scotia?
Yes. ECW is based in Dartmouth. Tell the team your town, water source and concern so they can confirm availability for your location. For equipment you already own, call first to discuss the model and service needed.
I searched for a plumber near me. Does ECW do general plumbing repairs?
ECW focuses on water treatment. It does not dispatch an emergency plumber or offer general plumbing repair through this website. Contact a qualified plumber for burst pipes, drains, fixture repairs or urgent household leaks.
Is my appointment confirmed when I submit the water-test form?
No. The form sends a request. The ECW team will confirm availability, the date and the time with you. You can read what the visit includes before submitting, or call 902-907-3864 to discuss your question.
