How to Remove Limescale & Calcium Buildup

Calcium buildup — not only is it icky to look at on the outside, but it can cause pretty costly plumbing repairs on the inside as well. When hardness minerals crystallize and adhere to your pipes and faucets, they narrow the waterways, making it more difficult for water to flow. In the business, we call this crusty, green, gunk limescale, and we don’t like it any more than our customers do!

Limescale Faucet | Water Softening | Aquarius Water Softeners

Fortunately, if you’ve been noticing these hard, white and green deposits often, there are several steps you can take now to ensure you banish them from your plumbing once and for all.

How to Remove Limescale From Your Pipes

  • Step 1: Shut off your water main — but before you do, grab a large pot and fill it with water first. You’ll need one pot of water per sink or shower drain that you plan to clear. (We suggest you do them all!) You may need to allow the DIY solution to sit for a while, so be sure you can forgo water for a bit before you begin.
  • Step 2: With your water reserved in pots and your water main off, it’s time to empty out those pipes. Turn on your taps completely and allow any remaining water to pour out and down your drain. You’ll want to flush your toilets as well.
  • Step #3: Start concocting your limescale removing solution in your sinks one ingredient at a time. First pour one cup of baking soda down each drain, then pour the vinegar slowly, filling it as much as you can. Keep in mind that best results take about 3 hours, so now it’s just a waiting game!
  • Step #4: While you wait, give your faucets and showerheads a good cleaning too. The easiest way to remove buildup is by putting your vinegar and baking soda solution in a bag and tying it around your fixtures. That way, it can sit and soak along with your pipes.
  • Step #5: Finally, it’s time to blast away the remnants with some boiling water. That’s where those pots you set aside earlier come into play! Heat them up and pour your boiling water down each drain quickly to create a forceful wave of water. (Just be careful of the splashback! We recommend doing this step with gloves and long sleeves in, just in case.) Then just clean up, turn your water valves back on and voila!

Prevent Further Limescale Buildup With Soft Water

Simple.. Or is it? If that sounds like a ton of work to you, we’d have to agree. In fact, we can think of one way to banish limescale and calcium buildup with a lot less effort required. Yeah — we’re talking about a whole house water softening and filtration system. Our Kinetico water softeners will ensure that no hardness minerals are allowed to invade your pipes in the first place, making cleaning them out a thing of the past.

Travis and his partner showed up on time for the appointment with plenty of notification and did an exceptional job on replacing our central air unit. They explained the whole process and did a walk-through at the very end and showed us how to use the thermostat. Very very happy with Aquarius on this appointment. Exceptional company!

I had my air conditioning system completely replaced by Travis & Dave and was very pleased with their level of customer service and expertise. They explained everything at the beginning of the process and kept me informed as they progressed. I’m now enjoying my new A/C again. Would highly recommend!

Technician provided great customer service. Worked quickly and explained everything including any charges before proceeding. Only gave 4 out of 5 stars because I was told I would be contacted 15 min before arrival so I could ensure I was home. Received no communication in advance, but was lucky to be at home when they arrived.

Thumbs up for... (1) GOOD COMMUNICATION, between the office/dispatcher and service technician and, to be appreciated even more so, between the technician and ourselves, the homeowners, by keeping us posted on his current timetable and probable ETA; (2) careful evaluation of our split-ductless AC system and its units, both inside and outside the house; (3) upfront and forthright TRANSPARENCY from the service tech, showing us both existing problem areas as well as potential problem areas, and apprising us of precise cost(s) involved in rectifying those situations; (4) a demonstration of professional expertise in identifying the primary problem - in this instance, an ever-so-slight but incremental leak of coolant; (5) SUCCESSFULLY making the necessary repairs and restoring the system to proper functionality - which, ultimately, is what we were in pursuit of; and (6) throughout this whole process, encompassing a period of more than three hours, Aquarius' service tech, David Boggie, was altogether CORDIAL and PERSONABLE.Thank you!

Our water heater went out on Fri evening. We called Aquarius early Sat morning and they said earliest they could get out was Mon. On Sun I received a text confirming our Mon appointment but on Mon morning they called and said the earliest they could get to us was the following week !We should be without hot water till then ? We are not a new customer…. 5 months previously we had a new furnace and air conditioner installed at quite an expense. I am appalled at their service or rather lack there of ! As an established customer they felt waiting approximately 10days without water was acceptable Bad, Bad, Bad !Two weeks later…The air conditioner Aquarius installed in Dec failed to cool when we turned it on on our 1st warm days. After the poor experience I had had with them I didn’t want to deal with them again but since it was under warranty I had to. We were told we would have a technician out Wed morning. After waiting at home all day they called and canceled at 4pm. We were rescheduled for Fri morning. We had several calls during the day with updates At 5:22 pm we received a cal the tech would be here at 6pm. We cancelled our dinner reservation and are awaiting his arrival.I realize our air conditioning is not an emergency but we have spent 2days waiting for our scheduled service. This is in addition to the 10days they wanted us to wait for a new water heater(which I do think is an emergency) I feel bad for the tech who I’m sure has had a long day and must now come at 6 on a Fri evening. Once again I repeat Aquarius has failed us again !!Wow !!!Now July ….it continues !! The duct from our air conditioning system has come loose and is spewing cold air in my basement. A service technician arrived and said the wrong connection was used. He said he would order the right part and return the next day. (Wednesday) The appointment was scheduled for today for between 12 - 3. When no one arrived by 3pm, I called and was told the part hadn’t arrived and they would reschedule for next Monday…5 days out.UGH…. I would have thought someone could have called before I wasted several hours waiting and now I can look forward to several days without efficient air conditioning and another day of waiting for a technician. Life is too short to have to deal with such repeated poor work and lousy service !! Oh, but they did say they’re sorry 😢

Micah Williams plumbing technician performed excellent job inspecting our house plumbing system, recommended new water heater because the existing one is over 17 years old. Within 4.5 hours the new water heater was installed with quality and workmanship exceeding my expectations. The purchase price was great as well as the purchase financing option. Over service rating is Excellent!

EVERYONE at Aquarius is extremely customer oriented! From first contact with customer service: "Thank you for calling Aquarius Home Service, How can I make you smile today?" (that happily delivered addage always does), all the way through to their exemplary Home Service techs, I have always felt well taken care of; as though their #1 goal was to insure my needs be met, to my highest satisfaction. Aquarius Maintenance technicians are polite and respectful of my home and personal time. They go to great pains to take pictures of any equipment they're working on & point out current issues along with potential future things to be aware of - all in plain English - so I can make informed decisions on fixes needed now or plan pros & cons of 'holding off for a while'. They don't push, they give facts, share expertise, let me decide. . . . and make me smile, everytime.I will happily encourage friends & family to call Aquarius for home service.
