a mixing valve at the water heater is the cheapest way to achieve this

I assume on-demand HWH is exempt from the 140 requirement and can be set to 120 directly right?

if your flush tower has the clip ears on the overflow tube then all you need is this one

The 3/4” pex is downstream of the meter.Oni-kun wrote: ↑Dec 11th, 2017 9:37 amHi
Thanks so much for answering all theses questions for all these years.
I'm having low volume/low pressure problems in my house. If more than 2 fixtures are used it can cause one of them to basically be a dribble. I measured my flow rate with a bucket at the laundry tub in the basement and it takes about 9.33L per minute only. So I decided to check to see what diameter service line I'm getting or if I have a PRV (it appears I don't). Recently we renovated a washroom and it became more apparent when we put in a Grohe rainshower, it was limited to 2.5gal/m and I took out the flow restrictor and it seems to have helped but it still isn't great.
I think I've got a weird situation where it appears that a PEX pipe is running from the curb into my house. (see pictures) I measured the outside diameter and it's 0.625inches or 5/8inches. My friend whos quite handy said it looks like it's attached to a fitting then attached to the copper so it probably has reduced the inside diameter by quite a lot, but he's no plumber.
Is this a really unusual setup?
What kind of inside diameter do you think I'm actually getting with a fitting like that?
Do you think there is any point in trying to upgrade the service line to a larger size to solve my problem? I don't want to spend a ton of money only to find out it doesn't help my shower.
How likely is it that I have PEX running all the way to the sidewalk shut off valve or do you think someone ran copper up to beside the wall but just put pex through the foundation?

Do you know where a backflow prevention valve is likely to be installed? Would a problem with it cause issues with water pressure?
Dec 13th, 2017 5:24 pm
A backflow preventer is installed anywhere where a possible back siphonage could occur if the water pressure is shut off or a loss in pressure such as on an outside faucet where there is a chance that a garden hose lying on the ground in a puddle could accidentally siphon backwards through the valve contaminating the potable water supply. Also installed on the supply line feeding a hot water boiler system or such so that the water in the heating system can't come back and contaminate the potable water. These won't affect the pressure in the rest of the house as they are at the end on lines feeding an individual fixture.
