TIL why you're not supposed to cook or drink hot tap water - it's the lead (and other heavy metals) (www.epa.gov)

Hot water dissolves lead more quickly than cold water and is therefore more likely to contain greater amounts of lead. Never use water from the hot water tap for drinking, cooking, or making baby formula.

We also had a smaller tankless, but we couldn't shower and use the washing machine on hot at the same time. All tankless water heaters have a flow rate limit depending on their size.

Must have been a small one I guess, but I don't see how a (small) tank could change that? But I'm no plumber so what do I know ☺️
