Water: Pressure, Temperature

A week or two ago we woke up to what sounded like rain. Since it had rained the day before, it wasn't startling... Until we heard someone shouting "Hola" from the street to get our attention. (Everyone has a gate separating their front door from the street and almost no one has a doorbell to get their attention, people just call you if they're at the door.) The lady who was kind enough to stop and get our attention informed us that our clean water tank on the roof was pouring clean water out of the top and running all down the back of our house and down the street.

Apparently the valve that regulates when the tank is full, like the bulb in the tank of a toilet, was broken. Then, the hot water heater went out. We don't know if the water shorted it out or if its age took its toll. Since then we've been using cold water and manually turning the water on to fill the tank and turning it off quickly when it started to overflow.

Today it was finally fixed! And, in addition, the trickle of water we had due to low pressure was also fixed! That first shower felt amazing.

Edited to add that another consequence of higher water pressure are the leaks we have discovered at the water hoses. It seems they are not built to handle any pressure higher than a trickle.
