It takes a few minutes for my tankless water heater to warm up, so we end up wasting a lot of water in our shower. Is there a way to avoid this? A friend mentioned a “comfort valve” or something? What is it and how does it work? Or is there another solution? Thx!
I don't think I've ever seen a shower in the US (assuming you're in the US) without access to the plumbing somewhere, I'm sure they probably exist somewhere, but it's not common in my experience, usually there's a little access panel on the other side of the wall somewhere, maybe hidden in a closet or behind a piece of furniture or something. If there's not, I'd consider adding one anyway, at some point if you're there long enough you're probably going to want access to it for some issue or project that comes up down the line.
They make small tankless electric water heaters that run off of regular 110V outlets for heating a single sink or shower, if there's convenient electrical nearby you may be able to just hook one of those up.
This is not my experience at all. I haven't had a single house where the plumbing was accessible
Living in the US I've never seen what you're describing
What part? Most houses I've seen in the Northeast either have some kind of access panel, or the shower is backed by a closet in another room where you could cut in if you needed to.
I'm in Jersey and I do not have that on my home. The only home I can think of that had it was my childhood home. Current home is 1920s, childhood home was probably 50s, teen home was 80s, and lived in various other places after that, and really never saw the access panel, though I agree it makes sense to have.
Form over function, can't have people judging me for my prudence.
The house I purchased is the first time I've ever even seen access to shower pipes. I've got an access panel in my closet to a space above the garage that has access to the ones for the guest bath. I'm pretty sure it's not intentional either since the space goes to the master bath as well yet the shower is set up in a way that doesn't have access.
In my experience you usually have to tear out parts of a wall to access shower/tub plumbing. Definitely seems dumb now that someone pointed it out.
Cheapskate subdivision builders commonly build on concrete slabs anymore with no way to access plumbing.
Building on a concrete slab doesn't exactly make a difference when I'm talking about an access panel in a wall though
Yeah it never goes through the attic.
Never seen that. Always gotta break open dry wall for that kinda work.
