This requires precision tools. It should be checked every 300 hours by our trained mechanics to maintain engine power and easy starting.

Yes, drive a copper rod into the ground and connect it to the generator's grounding terminal for safety against electric shocks.

Usually 6-10 hours depending on the fuel tank size and load. Let it cool for 30 minutes before refueling.

Always use a rigid, reinforced spiral suction hose. Soft hoses will collapse under the extreme suction power of Honda pumps.

It cuts fuel supply. Turn it off when storing or transporting to prevent fuel leaking into the engine oil.

Close the choke fully, pull the starter cord briskly. Once the engine warms up (10-20 seconds), open the choke completely.

EP is standard mechanical frame (good for heavy loads). EU is Inverter, fully enclosed, silent, and provides pure sine wave for electronics.

Yes, Supreme high-pressure column pipes (blue pipes) are designed specifically for the deep water tables (300ft+) found in Nalanda district.

Yes, they handle up to 20kg/cm² pressure, making them ideal for connecting to high-head agricultural pumps in the Nalanda hills.

Use white uPVC for normal cold water supply. Use yellow CPVC for hot water lines from geysers, as it withstands boiling temperatures without melting.

In Bihar's heat, solvent dries extremely fast. Clean edges, apply Supreme Solvent Cement quickly on both surfaces, push, and hold for 30 seconds.

Likely a 'dry fit' mistake or using expired/cheap glue. Always use genuine Supreme cement and allow at least 2 hours of curing before applying water pressure.

Absolutely. Supreme plumbing pipes are lead-free, non-toxic, and anti-bacterial, ensuring 100% safe potable water delivery for your family.

Supreme Eco-Drain (structured wall) pipes. They are crush-proof under soil weight and far superior to heavy, fragile concrete pipes.

Unlike cheap plastics, Supreme's dense molecular structure is highly rodent-resistant. For critical areas, conceal them inside walls or use metal sleeves.

Yes, Supreme pipes contain UV stabilizers. However, painting exposed pipes with light water-based paint extends their life significantly in Bihar summers.

HDPE is black, flexible, and rolls up easily—perfect for shifting across fields. uPVC is rigid—best for permanent underground mainlines.

SWR (Soil, Waste, and Rainwater) pipes are the grey pipes used in buildings to quietly and safely drain bathroom wastewater to the sewer.

Use the built-in 'Door Tee' fittings to open the line and clear blockages manually. Avoid using boiling acid as it can distort PVC joints.

Rare in Bihar, but water freezing expands and bursts pipes. Supreme's polymer has high elasticity to absorb pressure better than GI iron pipes.

Use a Supreme Brass Threaded Adapter (FTA/MTA). It provides a perfect, leak-proof transition from metal threads to plastic solvent joints.

Supreme column pipes are 100% rust-proof, lightweight (easy to lift the motor), and reduce motor friction loss, lowering your electricity bill.

Fumes are strong during application; work in a ventilated area. Once dried (cured), it becomes an inert plastic weld and is 100% safe for drinking water.

Supreme offers specialized industrial PVC-U pipes that resist strong acids and alkalis, unlike metal pipes which corrode instantly.

For a temporary fix, use a rubber patch and pipe clamp. For a permanent fix, cut out the damaged section and glue in a new piece using two couplings.

Use Supreme's large diameter uPVC half-round pipes and downpipes. They efficiently handle heavy Bihar monsoon downpours without overflowing.

Hand-tighten first, then use a strap wrench for a final half-turn. Do not over-tighten with metal pipe wrenches as it damages the plastic threads.

Yes, Supreme Silflow tanks are multi-layered, UV stabilized, and designed to keep water cool and algae-free in extreme summer heat.

Always use good quality Teflon tape (wrap 5-6 times clockwise) on plastic threads. Avoid liquid paste as it can harden and crack the plastic joint.

Supreme's nylon-braided hoses are kink-resistant, handle high tap pressure, and won't become stiff or crack in winter like cheap green pipes.

The EPDM rubber rings used in Supreme push-fit joints are permanently lubricated and last the lifetime of the building without degrading.

Prasad Hardware Stores is the trusted authorized dealer. Every pipe has 'Supreme' ink-jet printed along its length to guarantee authenticity.

PVC does not sustain flames. Once the external fire source is removed, a Supreme pipe will self-extinguish rather than spread the fire.

Before concealing pipes in bathroom walls, cap the ends and pressure-test the lines with water for 24 hours to ensure zero concealed leaks.

Never use direct flame. It destroys the polymer strength and releases toxic fumes. Use pre-molded Supreme Elbows and Bends for corners.

Only use Supreme CPVC (yellow). Normal uPVC (white) will soften, sag, and eventually burst if exposed to water above 60°C.

Yes, we stock the complete range of Supreme agricultural tees, elbows, valves, and service saddles for all farm setups at Prasad Hardware.

Use a fine-toothed hacksaw or a specialized PVC ratchet cutter. Always deburr (smooth out) the cut edge with a file before applying solvent.

Plastics expand in summer. For long external runs, install Supreme Expansion Joints to absorb the movement and prevent the pipe from buckling.

You can, but it is unnecessarily expensive. It's best practice to use CPVC for hot lines and uPVC for cold lines to optimize your plumbing budget.

Supreme offers high-quality plastic taps and valves that do not corrode, scale, or leak, perfect for areas in Nalanda with hard water.

Schedule 80 has a thicker wall and handles much higher pressure than Schedule 40. For multi-story main lines, always use Schedule 80.
