Is it ok to have a bucket under temperature/pressure relief valve, rather than drain outside?
I am waiting to get my 30 gallon electric water heater installed. It is placed inside the bathroom , right next to the shower.
I would like to avoid running the valve through my floor or outside the wall, so am wondering if it is safe/common to just place a bucket underneath? According to this lowes tutotorial, it is : https://www.lowes.com/projects/repair-and-maintain/install-an-electric-water-heater/project
I have a few questions regarding this
1) How often does the t/p valve drain and how much water is expected? In other words, is a 5 gallon bucket more than enough as long as it’s emptied regularly? Any chance that more than 5 gallons will come out?
2) I will have an expansion tank. Will that help with minimizing the amount of water dripped from the valve?
3) Does water ever drip out of the drain valve or is that simply there just to drain the tank manually? If not, what is the pirpose of the pan?
4) What would cause a the temp valve to constantly run out water (until the shutoff valve is turned)?
