Abid bhai is logic pe mat believe kia karen.
Sometimes people have different symptoms due to different problems, so their deciphering differs.
You should go to any pump guy scrappy deal with him kay yar pump chaye lekin I'm not sure if it's pump. Pehle paisay poochlena and then if he says 2000 to 1500karwa lena phir jahan rate set hojaye ap kehna masla ye hai im not sure if it's pump.
Agar na hua ap purana pump lagwa dena wapis and ya to paisay wapis krdena aur agar uska apna mechanic hua to kehna check krkay apko pay karunga. Jitne ap maang rahay ho utne hi de dunga.
