Ghar ki plumbing mein pipe aur fittings ka sahi intikhab bohat zaroori hai — ghalat pipe ya dheeli fitting se leakage, seepage aur bar bar ki marammat ka kharcha hota hai. Is guide mein hum simple alfaaz mein samjhate hain ke PVC, CPVC aur GI pipes mein kya farq hai, aam fittings kaunsi hoti hain, kaunse tools chahiye hote hain, aur leakage se bachne ke 5 aasan tareeqay.
PVC vs CPVC vs GI Pipes — Farq Samjhein
PVC Pipes (Polyvinyl Chloride)
Safed rang ke halke pipes jo thanday paani ki lines, drainage aur waste water ke liye istemal hote hain. Sastay, zang se mehfooz aur lagane mein aasaan hain. Garam paani ke liye munasib nahi.
CPVC Pipes (Chlorinated PVC)
PVC jaisay hi lekin garam paani bardasht kar sakte hain. Ghar mein garam paani ki lines (geyser se bathroom tak) ke liye yahi istemal hote hain. Rang aam tor par cream/off-white hota hai.
GI Pipes (Galvanized Iron)
Lohe ke mazboot pipes jin par zang se bachao ke liye zinc ki coating hoti hai. Purani buildings mein aam thay; ab bhi main water lines aur bahar ki fitting mein istemal hote hain. Bhari, mehngay aur lagane mein waqt lete hain, lekin dabao (pressure) zyada bardasht karte hain.
Kholasa: thanday paani aur drainage ke liye PVC, garam paani ke liye CPVC, aur zyada dabao wali main lines ke liye GI.
Aam Fittings — Naam aur Kaam
- Elbow — Pipe ki direction morne ke liye (90° ya 45° ka kona).
- Tee — Aik line se doosri line nikaalne ke liye T-shape joint.
- Socket (Coupler) — Do seedhay pipes ko jorne ke liye.
- Bush / Reducer — Baray pipe ko chotay pipe se jorne ke liye (size tabdeel karna).
- Valve — Paani ka bahao rokne ya kholne ke liye (jaise gate valve, ball valve).
- End Cap / Plug — Pipe ke khulay siray ko band karne ke liye.
Bunyadi Tools Jo Chahiye Hongay
- Pipe cutter ya hacksaw (pipe kaatne ke liye)
- Measuring tape aur marker
- Solvent cement (PVC/CPVC joints ke liye) aur brush
- Teflon tape (threaded joints ke liye)
- Adjustable wrench / pipe wrench (GI fittings kasne ke liye)
- Sandpaper ya file (katay hue siray hamwar karne ke liye)
Leakage Se Bachne Ke 5 Tips
- Joints saaf rakhein — Jorne se pehle pipe ke siray aur fitting ke andar dhool, mitti ya tail saaf kar lein; ganda joint mazboot nahi banta.
- Sahi solvent cement istemal karein — PVC ke liye PVC cement aur CPVC ke liye CPVC cement. Cement lagane ke baad joint ko 15–30 second daba kar rakhein aur istemal se pehle khushk hone dein.
- Zyada na kasein (don’t overtighten) — Threaded fittings ko had se zyada kasne se thread ya fitting crack ho sakti hai — haath se kas kar phir halka sa wrench se tight karein.
- Paani se test karein — Kaam mukammal karne se pehle line mein paani chala kar har joint check karein taake choti leakage foran pakri jaye.
- Threaded joints par Teflon tape lagayein — GI ya brass ke threaded joints par 4–5 lapet Teflon tape lagane se joint airtight/pani-tight banta hai aur leakage nahi hoti.
