Kem Cho, friends! I am **Dilipbhai**, owner of **Shivam Water Solution** located on Vajepar Main Road in Morbi. For over 10 years, my team and I have been installing, repairing, and servicing domestic RO purifiers and commercial RO plants across Morbi, Rajkot, and nearby industrial belts.
If you live in Morbi or Rajkot, you know our regional water quality presents a unique challenge. Borewell water in our area frequently carries extremely high Total Dissolved Solids (TDS)—often ranging between 1,200 PPM to over 3,000 PPM—along with high hardness and silt. One of the most common complaints I hear from homeowners and office managers is: *"Dilipbhai, our RO tank takes forever to fill! The water is just dripping drop by drop. What is wrong?"*
In this practical guide, I will walk you through why your domestic RO purifier suffers from low water pressure and slow flow rate, how to diagnose it, and what you can do to fix it.

## Why Does RO Water Flow Become Slow in Morbi & Rajkot?
Before jumping into solutions, it helps to understand why this happens so frequently in our region. RO (Reverse Osmosis) technology relies on water pressure to force pure water through a semi-permeable membrane while rejecting heavy salts.
When input water contains high hardness, silica, and silt—typical of Saurashtra groundwater—filters clog faster, pump efficiency drops, and membranes scale up quickly. Here are the 5 major culprits behind slow RO flow:
### 1. Clogged Outer Pre-Filter (Spun Filter)
The external pre-filter housing mounted outside your RO unit traps sand, rust, mud, and suspended particles. In Morbi's industrial zones and residential pockets using municipal/borewell mix, this cartridge turns dark brown or black very quickly. When choked, it restricts incoming feed water to the main machine.
### 2. Scaled or Choked RO Membrane
The RO membrane has tiny pores (around 0.0001 microns). High TDS water causes calcium, magnesium, and salt minerals to deposit on the membrane surface—a process called scaling. Once scaled, pure water (permeate) flow drops drastically, while wastewater keeps running continuously.
### 3. Weak RO Booster Pump
Your RO system requires high pressure (typically 60 to 80 PSI) to push water through the membrane. Over time, pump heads wear down, bearings degrade, or power adapters (SMPS) deliver lower voltage. A weak pump cannot generate enough pressure, resulting in slow trickling water output.
### 4. Low Pressure in the Hydrostatic Storage Tank
If your RO unit has a pressure storage tank (common in under-sink or standard cabinet models), it uses an internal air bladder to push water up to your tap. Over 1 to 2 years, this bladder loses air pressure. The tank may feel heavy and full of water, but very little comes out of the faucet.
### 5. Clogged Carbon or Sediment Filters
Inside the machine, pre-carbon and inline sediment filters capture chlorine, volatile organic compounds, and fine debris. If these filters are not changed annually, mineral sludge blocks internal pathways, severely throttling water movement.

## Step-by-Step Troubleshooting Tips from Dilipbhai
Here are practical steps you can try at home before calling for professional service:
* **Check the External Pre-Filter:** Open the outer filter housing using your filter wrench. If the white PP spun candle looks muddy or black, replace it immediately. A fresh pre-filter costs very little and often solves 50% of flow issues instantly.
* **Inspect the Feed Water Valve:** Ensure the main diverter valve connected to your tap pipe is fully open and not partially blocked by hard water scale.
* **Test Storage Tank Weight & Pressure:** Disconnect the tank valve and lift it. If it is very heavy but water trickles out slowly from the tap, the internal air pressure is low. You can use a bicycle pump to add 6 to 8 PSI of air via the tank's Schrader valve.
* **Check Input Tap Pressure:** If your main overhead tank lacks sufficient height or supply pressure, the RO pump struggles to pull water. You may need a feed water booster pump if supply pressure is below 10 PSI.

## When Should You Call a Professional RO Technician?
While replacing an outer pre-filter is easy, internal components require special tools, pressure gauges, and genuine spare parts. You should call an expert technician if:
1. You replaced the pre-filter, but the flow rate has not improved.
2. The RO machine pump runs continuously without shutting off.
3. The wastewater outlet runs endlessly while pure water barely trickles.
4. You notice a sharp change in water taste alongside slow flow (indicates membrane damage).
Using improper membrane sheets or low-quality local pumps in Morbi's high TDS conditions will waste your money and fail within weeks. We always recommend genuine, high-rejection membranes (like Dow Filmtec or high-TDS specialized sheets) suited specifically for Saurashtra water.
