Why Your Whole House Water Softener Isn’t Solving Hard Water Above 800 PPM
Hard water over 800 PPM is a significant challenge to homeowners who are using only a Whole house Water softener. Though a water softener is best for average hardness, very hard water or high TDS water can saturate its ability. Most households end up with scaling problems in pipes and appliances even after the installation of a water softener, and they remain annoyed. For water with greater than 800 PPM hardness, a water softener alone would not be enough, and an RO plant may be the only solution that will work. This blog explains why softeners alone cannot handle very hard water, how an RO plant works, and why combining solutions can be beneficial in certain scenarios.
Understanding How a Whole House Water Softener Works to Remove Hardness
A water softener works primarily through ion exchange. Calcium and magnesium ions in hard water are replaced with sodium ions, reducing water hardness. While a water softener can efficiently treat moderate hardness, its efficiency drops significantly when dealing with hard water above 800 PPM. The resin bed in the water softener may become saturated quickly, and its effectiveness will be lost, along with the scaling issues created. Even during normal regeneration, very hard water or Water with high mineral content might also pass through with a partial treatment. It is only in these conditions that a Whole house RO plant can provide complete treatment. [1]
The Chemistry Behind Hard Water Above 800 PPM and Why Softeners Fail
Hard water above 800 PPM contains extremely high concentrations of calcium, magnesium, and dissolved solids. Standard water softeners cannot remove all these ions effectively because the ion exchange capacity has limits. High TDS water overloads the resin, and there is remaining hardness with it, which causes scaling in pipes, water heaters, and appliances. The chemistry is straightforward: ion exchange can only exchange a finite number of hardness ions. When hardness and total dissolved solids have progressed to this point, a water softener cannot be enough by itself, and an RO plant must be employed.
Limitations of Conventional Whole house Water Softeners in Extremely Hard Water
Traditional water softeners like widely known brands Eureka Forbes, Kent, Livpure, and more are generally built to deal with water hardness up to a level of approximately 600–700 PPM. Over this threshold, the resin is no longer able to efficiently exchange calcium and magnesium ions. Hard water over 800 PPM not only significantly lowers the performance of the softener but also causes scaling issues in pipes, water heaters, and household appliances. Most brands advertise their water softeners as being able to work with high hardness, but that’s not the case in practice; no standard softener can effectively treat water hardness greater than 800 PPM. High TDS water makes things even worse, as dissolved salt is not treated. For water over 800 PPM, a water softener alone will not do; a Whole house RO plant is the only viable option in most instances to avoid scaling and supply safe, low-TDS water. [2]
High TDS Water: Why Softening Alone Isn’t Enough
High TDS water contains dissolved salts, minerals, and other impurities that a water softener cannot remove. While a water softener reduces calcium and magnesium levels, it does not lower the total dissolved solids. Households with hard water above 800 PPM still face scaling issues even after softening. In these cases, an RO plant is required to remove Water with high mineral content completely. RO plants use a semipermeable membrane to reduce dissolved salts, producing soft water that is suitable for all household and drinking needs.
Scaling Issues in Pipes and Appliances Despite a Whole House Water Softener
Scaling issues occur when hardness minerals precipitate inside pipes, water heaters, and appliances. With or without a water softener, water harder than 800 PPM or very hard Water with high mineral content can cause ongoing scaling. Some dissolved solids or hardness ions may not be removed by the softener, creating minerals that build up in the system over time. Scaling cuts down on flow, ruins appliances, and incurs higher maintenance. In cases of hard water above 800 PPM, only an RO plant can effectively prevent scaling issues while ensuring low-TDS water. [3]
How a Whole House RO plant Treats High TDS and Very Hard Water Effectively
An RO plant is designed to handle Water with high mineral content and Water with hardness over 800 PPM that a water softener cannot treat completely. Whole house RO plants use a semipermeable membrane to remove calcium, magnesium, and other dissolved solids, providing water with very low TDS. By treating extremely hard water through a Whole house RO plant, scaling issues are greatly reduced, and appliances have a longer lifespan. In areas with borewell water exceeding 800 PPM hardness or very high mineral content, an RO plant is often the only solution that works effectively.
Combining Whole House Water Softeners and Whole House RO plants for Complete Hard Water Treatment
For households facing hard water above 800 PPM, combining a water softener and an RO plant can optimize results. The softener eliminates partial hardness to shield the RO membrane from over-scaling, and the RO plant eliminates high TDS water and dissolved minerals that remain. This keeps the system away from scaling problems, prolongs appliance lifespan, and provides safe, soft water for drinking and domestic use. For water with a level above 800 PPM, an RO plant is still the key element in attaining completely purified water. [4]
Maintenance and Monitoring Tips to Prevent Scaling and TDS Problems
Regular maintenance is necessary to get the best out of water softeners and RO plants. Regular regeneration of the resin in the Whole house Water softener ensures hardness removal efficiency is sustained. Monitoring TDS levels and regular replacement of membranes in RO plants are needed. Maintenance by cleaning and preventive measures avoids the problem of scaling within pipes and appliances. For homes with hard water over 800 PPM, regular checking makes sure that the Whole house RO plant is still treating high TDS water well, since a water softener by itself is not capable of treating such excessive hardness.
