Why does it take 90 seconds to get hot water from tank to faucet?

That's just how long it takes to get the water that is sitting in the pipe out. Unless you have a circulating pump on the line so that there is always hot water at the faucet, it always takes a bit of time for the water to get hot. The hot water is in the tank, not the pipe connecting it to the faucet. There is nothing in the pipe to keep the water hot.


Why would there be hot water overflowing from this pipe?

Not being able to see the pipe and not knowing where it is, it's kind of hard to know. If it is a cold water line and you have not shut off the hot water tank, the pressure from the hot water will back flow and hot water will come out of the cold side.

What causes brown water only when you turn the hot water on on the other side of the house The hot water in the kitchen above the hot water heater is always clear had a recirc pump installed in line?

This is a sign of residue in the hot water pipes. i guess at your part of the world, you must be using corrosive type of water pipes. The heat in the water helps oxidization of the inside of pipe and when the same pipe is not used to transfer of water in the pipe, existing water in the pipe caused corrosion so when the tap is opened after a while, the water that comes out is brown. To avoid this, you need to use the tap more often to stop the brown build up inside the pipe.


Hot water barely comes out of faucet cold water works fine how do i fix?

If shut off the hot water valve then you take off your supply line from your hot water valve to your faucet and then turn your hot water valve on slowly (with of course a bucket or something to collect the water under it) and if you can see you have water pressure and flow then most likely the problem would be in your faucet on the hot side. If you have no pressure or flow when you turn the hot valve on then it could be debris plugging your hot water pipe or your hot water service valve (angle stop, straight stop) which older galvanized pipes are known to do so. To fix the problem you would need to find out where the problem is then either fix or replace the faucet or replace the angle/straight stop or try back flushing the hot water pipe and or replace the pipe with pex or copper pipe.
