White Color Scale Removal in Domestic Water PVC Pipes

Thanks for reply. Is it safe to drink water once we cleaned the pvc pipes with muriatic acid.Please recommend any muriatic acid brand and method to clean.Thanks again

No specific brand. Whatever you can find in your local hardware or home building supply store is fine.

As for where to add it that up to you to figure out. As close to where your water source originates is best.

It will clean itself out by reacting with the minerals and be flushed away as your water runs in normal use.

Now, once you've removed the scale, how will you keep buildup from recurring? A water softener system? Or do you plan to remove the scale occasionally? If you keep up with it it shouldn't take as much as the first time. Like tcmtech said, muriatic acid works and does not affect PVC pipe. Metal fittings - faucets, valves, etc. - may be another matter however, depending on the metal's composition.

Short duration exposure to the metals commonly found in plumbing isn't much of a problem.

Chemically it's going to be going after the Calcium, potassium, sodium and other similar elements in the scale first. The stainless steel, Iron, Copper, Brass and like metals will be fine for the bit of exposure they will get.

The biggest concern I would have is making sure the piping has a good unrestricted exit point being as the scale breaks down it's likely going to get a bit chunky as it loosens up plus the gas bubbles the reactions will make help to drive it along pretty well.

Video worthy in my opinion!

My brothers plumbing has a silt problem (shallow well in a fine sand aquifer) so a few times over the years we have pumped air into his system (~ 5 CFM @ 40 PSI) right at the well pump discharge manifold to get a good air/water mix to scour the silt out of the lines.

It really works well but for the first few minutes as the bubbles start to break the silt up what comes out of whatever faucet or hydrant that is open is just nasty bubbling sludge!

It's what I expect the OP would be seeing with the acid flush of his system.

Thanks for reply. I don't think ,the air can flush out the scale as it is very hard unlike silt.

PVC is so cheap I would just replace the tube....unless you are looking at a major expense, then I would kick myself for not installing a water softener system to begin with, and buy one, then replace all the pipe....Trying to clean it all out will leave residual mineral deposits behind, and the formation will happen faster the second time...

Do you know where can I buy this water softener? I suffer all my life from har water: My hair, teeth, skin. What can I do about it?

please contact Kitec ind. India ltd. they will help you.

Insufficient data, but based on the rather high fluoride level shown, I would avoid using acidic compounds as these will all produce toxic HF vapor that can poison the unwitting.

Use tetrasodium EDTA chelant as is diluted to a few parts per thousand on the day the water line is to be cleaned with no human use of the water other than for washing on that day, or even sodium citrate, buffered with citric acid to a pH of 6 would work well on your water. You need to know if there are heavy metals or transition metals present as well, however, so the safest recommendation is have full metals panel done at least once by an accredited laboratory.

Is there any chance of actually treating this water in a central location prior to pipe admission? That might go a long way to ameliorating the issue.

Ohh! great! This is a good and Informative post. In this post I truly got quality information. Thank so much!

Your article content is being very much interested, I am very impressed with your post. I hope to receive more great posts.
