There is stress on that hose, opt for a longer one as this one will fail.

I think it's installed at the height where the nozzle could rest on the ground to actually reduce stress on the hose. they just need a longer hose

I’m not wise to these things but would a longer hose reduce pressure? Sort of like the longer you make a straw the harder you need to suck to get liquid through?

It won't make a meaningful difference. The flow restrictor in the showerhead is going to do much more than a longer hose ever will.

I have a well and had abysmal pressure in my shower head despite the system sitting at 60psi. Removed the restrictor and it was a game changer. I felt a bit bad but the excess water goes into the leach bed anyways so..

I've removed them before too. It was a huge improvement, but it also drained the water heater very quickly. I probably should have changed the showerhead instead, but it was a rental and I didn't have much money at the time.

We have a 50 gallon and there are only two of us so I think we will be okay. I'd go tankless but the water heater was just replaced prior to us buying the house so it doesn't seem like a good investment atm.

Tankless electric use resistance heaters which costs $$$$ to use, and need high current wire and breakers which costs $$$$ to install. Tankless gas, if you've got a sufficient gas line (can go up to 199kBTU) only need a little electricity.

Ok, so your using the electric tankless to provide supplemental heat when the tank runs cold, then. Here in California, electricity runs 35+ cents/kWh, so the relative cost is more dramatic. My local city is now outlawing gas appliances for new construction and 50%+ remodels, and they can have my natural gas tankless water heater when they can literally pry it out of my cold dead hands. I just finished my 90% remodel + 9% addition, so I'm well positioned that way.

Recirculation just keeps the HW pipes (and contents) warm, which should be insulated with foam. You can use a timer to decide when it runs. Gas heat in a tankless is pretty much instantaneous, but there is a "cold water sandwich" issue when there not enough mixing in the pipes.

most houses have many feet of pipe moving that water to the hose, and an extra 2 won't make any difference, but early failure of the hose connection due to stress will cause a problem.

Having been blessed with only a short straw I have never heard of your complaint before.

Yeah that makes sense. I’ve never had an issue with straws before I just remember seeing a physics video about it (probably veritsaium) and was just curious

The issue isn’t the length of the straw, that friction is negligible (unless the straw was extremely thin). The issue with a longer straw is the difference in elevation at the point of suction compared to the elevation of the liquid. If you have a silly straw you need much less (negative) pressure than if that same straw was straightened out.

Oh no I fully understand that, I’m just curious as to the effect of longer hoses is all :)
