Kem Cho! Welcome to the official blog of Shivam Water Solution. I am **Dilipbhai**, and for over 10 years, I have been installing, repairing, and servicing domestic RO purifiers and industrial commercial RO plants across Morbi and Rajkot. Every day, homeowners from areas like Vajepar, Ravapar Road, Mahendranagar, and Sanala Road come to my shop with a very common complaint: *"Dilipbhai, the RO purifier tank takes hours to fill! Water is coming out drop by drop!"*
A slow-filling RO purifier is frustrating, especially during peak household hours in the morning. In our region—where groundwater TDS (Total Dissolved Solids) and hardness levels can be exceptionally high—low water pressure and trickle flow are very frequent issues. In this comprehensive guide, I will walk you through the top reasons behind low pressure in your RO system and how we fix them.

## Why Does RO Water Flow Become Slow in Morbi & Rajkot?
Before diving into repairs, it helps to understand why this happens specifically in Saurashtra. Groundwater across Morbi and Rajkot contains high levels of dissolved salts, calcium, and fine silt. Over time, these mineral deposits clog filters much faster than in regions with soft municipal tap water.
When water cannot pass freely through the filtration stages, your system loses pressure, resulting in slow filling or no water output at all.

## 5 Common Causes of Low RO Water Flow & How to Fix Them
### 1. Clogged Pre-Filter Candle or Sediment Filter
* **The Problem:** The outer pre-filter housing catches mud, sand, rust, and heavy sediments. In areas around Morbi's industrial belt, fine dust often chokes the outer polypropylene filter within 2 to 3 months.
* **The Fix:** Open the pre-filter housing using a spanner key and inspect the candle. If it looks dark brown or black, it must be replaced. I recommend changing the outer pre-filter candle every 3 to 4 months in Morbi and Rajkot to protect internal filters.
### 2. Scaled or Foul RO Membrane
* **The Problem:** The semi-permeable RO membrane has tiny pores (0.0001 microns). High TDS water causes hard scale deposits (calcium carbonate) to form on the membrane surface, blocking water molecules from passing through.
* **The Fix:** If your RO membrane is clogged, water production drops dramatically while wastewater output increases. In most cases, a membrane with hard scale buildup needs a complete replacement. Using an anti-scalant or high-quality membrane (like Dow Filmtec or equivalent) rated for high TDS will ensure a longer lifespan.
### 3. Faulty or Weak RO Booster Pump
* **The Problem:** An RO membrane requires at least 60 to 80 PSI of pressure to force water through its pores. If the internal booster pump weakens due to worn-out bearings, head leakage, or a faulty SMPS power adapter, water flow will drop to a trickle.
* **The Fix:** A technician needs to test the pump head pressure using a pressure gauge. If the pump is delivering below 50 PSI, we either recondition the pump head or replace the booster pump assembly.
### 4. Loss of Air Pressure in Storage Tank (for Hydro-Pneumatic Systems)
* **The Problem:** Many under-sink or standard RO purifiers use a pressurized metal/plastic tank with an internal rubber bladder. Over time, the air charge bleeds out. Without internal air pressure, the tank cannot push stored water up through the tap.
* **The Fix:** Locate the Schrader valve on the tank (similar to a bicycle tire valve). Check the air pressure using a pressure gauge. It should be between 6 and 8 PSI when the tank is completely empty of water. You can pump air manually using a bicycle pump. If water comes out of the air valve, the internal bladder is ruptured and the tank must be replaced.
### 5. Kinked Food-Grade Tubing or Clogged Carbon Block
* **The Problem:** Sometimes the solution is very simple! A bent silicone tube behind the purifier or a choked activated carbon block can restrict flow.
* **The Fix:** Pull the purifier slightly forward and check all white tubing for bends or kinks. Also, replace activated carbon blocks annually to maintain full flow and eliminate bad taste or odor.

## What Can You Check Yourself at Home?
Before calling for service, try these quick DIY checks:
1. **Check the Main Tap:** Ensure the feed water supply valve connected to your raw water pipe is fully open.
2. **Inspect the Pre-Filter:** Look through the transparent housing (if installed) to check if the pre-filter candle is heavily soiled.
3. **Power Supply:** Make sure the SMPS adapter light is glowing continuously without flickering.
If you have checked these and the flow rate is still slow, it is best not to run the booster pump dry, as it can cause the motor to burn out.
