Leaking faucet connection

Although it looks like the leak is coming from the hose side, it might still be coming from the swivel nut. Snug it up no more than 1/8th of a turn. If leak persists, snug it again. If still leaking, replace the supply flex.

Transmission fluid blowing out of dipstick tube

Sounds like you may have overfilled your transmission. I would take the vehicle to a transmission shop and have the fluid changed out. Many shops run periodic specials on this type of thing.

Ive replaced 3 toilet fill valve with 440a Fluid master fill valves height is good water level good.After a while it sounds like there is leak by from all toilet.Flappers have been replaced. What coul

check the overflow pipe in the cistern tank as some fill valves do not stop completely but allow input of water after the noise has stopped. This allows the water level to rise up and the water to flow out into the toilet bowl. Reduce the water level height by adjusting the cut off level and when the water rises past the new level the increase pressure on the valve will shut it off.

Leaking to drain? Adjust float height to keep water below overflow ... or change flapper if it doesn't seal. Leaking to floor? Check either end of supply line; or check seal between tank and bowl.

Why does the flap close before water flushes

the flapper is pushed down too far on the vent tube. leave about 1/2 inch of space between the bottom of the flapper flange when you seat it over the vent tube. make sure the flapper is level. if the flapper is too close to the bottom of the vent tube, it will slam shut before the flush is finished.

The flapper leaks, replaced it twice and it still leaks. Is there something in the design that is wrong. can I get a good alternative?

There are different types of flappers at Lowes or Home Depot. Turn your water off at wall and take flapper to either store and service people/plumbers will assist you for free to get right one that works and also show where and how to adjust.
