Running 3/4" piping from the 1/2" feed will slightly decrease the pressure loss, meaning you'll get more pressure at your fixtures, but the difference will probably be very small. Most of the pressure loss will have already occurred in the 1/2" line before it reaches your house. So, it will help some, but how much will depend on how long the run is ...

Flow resistance, like electrical resistance, increases with conductor length. If you are going a long way (say, over 50 meters) you will get better flow by running a larger pipe. The volume is a non-issue - (static) pressure won't go down even if you install one of those giant green gas storage containers in the yard. In no case will you get more flow than ...

First as Henry Jackson mentions the low flow shower heads are part of the the water consumption laws passed in the US. I am not sure how the US compares to other countries. I have done construction in France and in Spain and nobody has mentioned this to me and I never really thought about the pressure after installation - if I were to guess they seem to ...

In the US the low-flow shower heads are mandated by federal law, so it may not be easy to find a non-restricted one. I am not a lawyer but I would think that advertising the un-restricted flow rate would be a subversion of the law and therefore unlikely to be legal. If you want a non-low-flow shower head I would just take the restrictor cap out of any ...

I ended up fixing this issue by capping off the heads and turning the system on for hours at a time as opposed to just a few minutes. This extended time running the system while capped off allowed buried line breaks to be revealed. There were multiple line breaks and crushed heads run over by vehicles in the past. I fixed all this last summer. As a ...

Your diagnostics so far point to the indirect hot water heater coil leaking potable water into the furnace loop as the most likely issue. You could perhaps verify if you can shut your hot water down for a few days (not convenient, I know.) Depending on the overall condition of the indirect water heater tank, the coil can often be replaced as a part, if the ...

Since you do have hot water coming out of other faucets it is most likely your shower valve. Many of the single handle shower faucets have a cartridge valve that is very easy to replace. The cartridges are specific to the faucet so you will need to look up your model. I had a similar problem with mine. The cartridge cost around $60 and took about 10 minutes ...

"shouldn't I have seen a more substantial improvement in pressure and/or flow by upgrading to a NEW, much larger 1" dia. line?" Not if the downstream galv. pipe at the entry point to your home is in the same condition as the pipe you replaced. "does anyone think that the 3/4" meter at the street may be causing a restriction at all?" Yes, but it is ...

The time delay between the hot water tank and the places where you use it is entirely determined by the distance between the two, which you have not changed. Note that larger tubing would be counterproductive here, because the flow is almost entirely determined by the outlet device, and you want to minimize the amount of cold water you need to drain before ...
