0.5 hp motor low pressure in single home.

upgraded 1 hp good at bengining eventually after 2 years same problem.

Self primer 1 hp motor pump mono block

removed air by unscrewing the

How do i fixed CRI 1 hp 2 years old Pump low pressure?😮😲😯🙀

beofore it just like low pressure tap.

while i removing all the water from pipe dropped in the sump with high pressure (this also clears clogging in the sump.)

after i removed suction cup NRV or Non returning valve, and sparyed wd 40 fitted again tested.

Results shocking

Now its pressure like 1.5 hp motor..  neglected since 1 year..

maybe issue with rusted suction or air bubble. whatever is saved 800+ repiaring charges or 1000-2000 repair charges.

Air and Pressure Problem Solve filling water frequently

Note: different pumps have different NRV make sure buy exact size.

Low Pressure NRV with dust Mono block pump

reasons:

Low pressure in a water pump can be caused by several factors, including:

1. Clogs or Obstructions: Debris or sediment in the pump or pipes can restrict water flow, leading to low pressure.
2. Air Leaks: Air entering the suction line can disrupt the pump’s ability to create pressure, causing low output. replace NRV
3. Worn or Damaged Components: Wear and tear on components such as seals, impellers, or bearings can reduce the pump’s efficiency and pressure.
4. Incorrect Pump Size: If the pump is too small for the application, it may not generate sufficient pressure.
5. Suction Head Issues: If the pump is located too far above the water source (high suction lift), it can struggle to draw water effectively.
6. Insufficient Power Supply: Low voltage or inadequate power supply can lead to reduced pump performance.
7. Closed Valves: Valves in the system that are partially or fully closed can restrict flow and lower pressure.
8. System Design Issues: Poorly designed piping systems, such as excessive bends or long runs, can cause pressure drops.
9. Cavitation: If the pump is operating below its required suction pressure, it can lead to cavitation, which reduces performance and pressure.

Little brocuher comes with fridge

is voltage fluctuation cause ice buildup in refrigerator

Yes, voltage fluctuations can indirectly cause ice buildup in a refrigerator by impacting its cooling performance; when the voltage is unstable, the refrigerator may not cool effectively, leading to higher internal temperatures which can result in more condensation forming and freezing into ice on the evaporator coils.

Ndt235231aqmc2pe review

after 7 months grinding noise and comes with broken seals from relaince digtals, there is no warranty on seals and glasses. technicin won;t come for installation and demo. very pathetic.

Beware of defect products >> use replacement periods.

Modes:

chef mode:

what is mini ref in fridge

What to do:
Defrost the fridge:
If you see ice buildup, defrost the refrigerator by removing food and leaving the door open for a few hours, or use a hair dryer on a low setting to melt the ice.    its frsot free and turned off fridze whie but provlem again.

Check the door seal:
Inspect the door seal for any tears or gaps that might be allowing too much moisture in.   yes door seal leaking.. slightyly

Replace the fan motor:
If the noise persists after removing ice and the door seal appears intact, it’s likely a faulty fan motor and will need to be replaced by a qualified appliance technician

Faulty fan motor:
A worn-out bearing within the fan motor can also produce a grinding noise as the fan struggles to rotate

What does “min” and “max” mean on a refrigerator?

On a refrigerator, “min” stands for “minimum” and “max” stands for “maximum,” indicating the lowest and highest temperature settings you can adjust the fridge to, respectively; essentially, “min” is the least cold setting and “max” is the coldest setting.

why earthing needed home?

faluty current in home appliance

Earthing is necessary in a home to protect people from electric shock by providing a safe path for any fault current to flow directly to the ground,

Buld test

Eath & Live  = Buld no dim or flicker   earth is good, dim or flicker faulty earthing  NO light no earthing

Right Hole >>  electrical or live, left hole nutral , upper earth

Multi meter test

generally in india 240-250 voltage so we set 600volatage on multimeter  (750v in some generally 250+ above)

try earth + neutral volts = not more than 5v

eaarth+ live = 240 (which should same as on nutral + live with may little diffrence upto 2-5volts).

generally in india right side >> live/current/

left side: neutral>>

you can also use tester which is light turns that is live/electrcity.

Connect the test leads to the circuit: black lead first, red second. Note: ac voltage does not have polarity.

On a multimeter, the red lead is considered “live” or positive, meaning it should be connected to the power source or the higher voltage side of a circuit when measuring voltage.
Key points about multimeter colors:
Red: Positive (live)
Black: Negative (neutral)  or eathing

earthing test with multimeter

red into netral which left side of scoket, earth upper black hose.. not more than 5 volts difference. ideally same.

Reading interpretation: A low resistance reading (close to zero ohms) indicates a good earthing connection.

when i put 200v its indicating 0.08 when i put 700v it indicating 0.01

(insert into live & neutral and insert into live & earth it should be same or difference not above 2-5 volts.)

Red on v, Blac on Com

Red intor netral portal which is bottom left  >>

Black in earth port upper  >>

if reading more than 3 volts , if there is overload  it can go 5 volts, maxium allowed voltage between neutral and eartn not more than 5.

(live to neutral) from the second (live to earthing). After solving that, add the number of volts from your third reading (neutral to earthing). If the number is greater than 2 V, then your earthing may be faulty. Otherwise, the outlet is safe to use.

• For example, if your first reading was 230 V, the second reading was 231 V, and the third was 0.5 V, then your formula would be (231-230) + 0.5, which simplifies to 1.5 V.

which side is live on a socket

Rigtht = postive / live

Left= negative /

should i maintain ground earth

Yes, you should definitely maintain your ground earth (also called earthing) as it is crucial for electrical safety and reliability, and a poorly maintained ground can lead to potential hazards like electrical shocks and equipment damage; regular checks and maintenance are essential to ensure its effectiveness.

• Inspect connections:

  Check all connections within your grounding system, including those to ground rods, electrodes, and conductors, for corrosion or looseness. 
• Address corrosion:

  If corrosion is present, clean or replace corroded components to maintain good conductivity. 
• Environmental factors:

  Consider the environmental conditions where your grounding system is located, as factors like soil type and moisture can affect its effectiveness.

Can i pour water on earthing

can i make garden on earthing

Yes, you can absolutely create a garden on top of an earthing system (grounding rod), as long as you are not directly touching the metal rod itself; planting around a grounding rod is perfectly fine and considered a form of “earthing.

WD 40 Lubriacant or not

WD-40 Multi-Use Product is not really a lubricant. Fact: While the “W-D” in WD-40 stands for Water Displacement.

wd 40 + moto max lube recommeded by company. WD-40 was designed to displace water. It’s NOT a lubricant, and it doesn’t preserve rubber. If you want to help preserve rubber suspension bushings (and CVT boots, and other rubber parts) spray them with automotive silicone spray. That will protect the rubber surface and help maintain flexibility.

WD-40 Specialist_® Silicone Lubricant safely lubricates, resists water and protects metal and non-metal surfaces such as rubber, plastic and vinyl. Once dried, this formula leaves a clear, non-staining film that doesn’t stick or make a mess, so it won’t attract dirt.

Silicone Lubricant Spray:

Rejuvenates & Shines Surfaces, Lubricates Most Plastic, Rubber & Metal Parts

short answer: check applicatiance & stabliazer power rating should match.

Choose a stabilizer with a higher power rating than your appliance, preferably 20% to 25% more. For example, if your device has a power rating of 1000 W, you should choose a stabilizer that has a power rating of at least 1200 W or 1250 VA.

thumb rules is read stablizer capapacity and for refrigerator size.

ex: upto 300 liters,  or upto 600 liters etc..

check regridgerator information for power rating

230v*0.5a

230*0.5=115w  (271 units for year 2 start inverter fridge.)

the appliances or device will consume double the amount of power on start-up than it does while working.

To get the maximum power – Multiply “230 x Max rated Current” of all the equipment that are to be connected to the stabilizer. Add a 20-25% safety margin to arrive at stabilizer rating.

Stablizers based on Capacity size 300litres below 200l etc

250 volts is generally part of the standard voltage range for India, which is 220–250 volts

should refridgerators need stablizer for stablizier free models

stablizer free operation 110-300v means  it cutt off the power when below or above voltage. not stablizes add+ or – volatge stablizers .

may not be necessary unless voltage in your area shoots up or down much above or below the limit in which the appliance can operate 110-300v.

many recommeds for invererter AC, fridges stablizers?

in case of power flucutate, PCB comboponets may burst in in the refrigerator which cost higher than external Stablizer..

How fan speed settings affect cooling & power usage in AC

Setings fan mode auto is helpful. in TURBO Mode Both AC & FAN run higher speed.

An air conditioner (AC) fan’s purpose is to circulate air throughout a home to keep rooms cool and comfortable. The fan is located in the blower unit and is controlled by an electric motor.

Power usage

uses 5% of  compressor power usage.

The fan’s power consumption depends on its speed, size, type, and motor efficiency. However, fans use relatively little power, and the compressor uses the most. Using the AC on a higher setting with a lower fan speed might use more electricity because it takes longer to reach the desired temperature

Does a refrigerator need regular service?

No, Regular maintenance tasks may include cleaning the condenser coils, checking and replacing the door gaskets if necessary, and ensuring that the temperature and humidity levels are set correctly. It’s also important to periodically check for any leaks or unusual noises that may indicate a problem.

inverter vs non  inverter refrigerators

Inverter refrigerators are more energy efficient than non-inverter refrigerators because they use a variable speed compressor that can adjust its speed based on cooling needs. Non-inverter refrigerators use a fixed speed compressor that runs at the same speed all the time

cost of refrigerator maintenance annual

In Hyderabad, India, the average cost of refrigerator maintenance is between ₹1000 and ₹2000 for annual maintenance service.

refrigerator compressor gas life span

A well-maintained compressor can last up to 20 years, but typically lasts 8–10 years. Poor maintenance, lack of lubrication, and environmental factors can shorten the compressor’s lifespan.

Why refrigerator compressor gas leaks ealry

Refrigerant gas leaks in a refrigerator can be caused by a number of issues, including:
Faulty valves: Faulty valves on the compressor or condenser can cause leaks.
Damaged components: A component of the compressor or condenser may be damaged.
Improper installation: If the copper pipe to the compressor is not welded properly, or if the valve is damaged or not good quality, refrigerant gas can leak over time.
Vibration: The vibration created by the compressor motor can damage the compressor connection and cause a leak.
Pinhole leaks: Pinhole leaks can also cause refrigerant leaks
