Common Water Problems in Sarnia and Surrounding Areas

Here are 3 of the most common problems we see in the Sarnia area, and how they can affect your water

Chlorine

Chlorine is commonly used to treat municipal water and is generally safe for drinking, cleaning and bathing. However, it often causes an unpleasant, bleach-like taste or smell.

Total dissolved solids

Also known as TDS, these are organic matter, salts and metals in your water. They can cause a bitter, metallic taste, corrode your plumbing fixtures and shorten the lifespan of your appliances.

Hard water

Hard water causes damage including buildup on faucets and showerheads, spots on dishes, dry hair and skin, dingy laundry and issues with water-using appliances.

-Shawn, N.

“This place is the best water place I have dealt with...

-Dennis, S.

“Jess is such an awesome employee at the Sarnia Culligan location...

...she’s always so friendly when I walk in, greets me with a smile everyday and helps me fill my water jugs! Such a great employee!

-Ashley, C.

“Wonderful, trustworthy service.

Installing a water softener was the best decision. I wish more people had told me it was important to test and consider much earlier. My pipes and bathroom fixtures thank me and my hair is soft again!

-Kristin H.

“Safe, clean-tasting water directly from the tap is wonderful.

Had we realized just how affordable and stress-free the installation of our new reverse osmosis system was, we would’ve done it years ago.

-Anthony M.

“They helped me pick the best solution for my home.

They explained all the different options. I am happy with my water softener and reverse osmosis systems! Quick install, and looks like low maintenance.
