Hi all, if there's an autocrosser that wants the job, I'd like them to have it.

I suspect the folks that built my largish house skimped on the insulation for our water pipes, if not forgetting it altogether. The main symptoms are hot-ish water from the cold tap in the Summer, and a huge new water heater at full-temp but only so-so hot-ish water for showers.

I imagine the job would be to bore holes for a scope, and/or remove outside siding etc, to verify, and if so, find a clever way to fix it. Spray-in expanding foam?
Thanks,
Joe

Insulation only slows the rate of temperature change, so if the cold water isn't used for a few hours, it will absorb heat, unless you can somehow stop heat from getting to it altogether. I actually like warm water from the cold side to wash up and not have the gas water heater kick in. The hot water under-performance sounds like you have a blend system in which cold water is introduced into the hot lines to prevent scalding. That can be adjusted, I suppose. Just to be clear, I'm not a plumber, but I do occasionally play one on a popular auto-x enthusiast forum Very Happy
