If you want regulation, find and purchase a Watts regulator. They are not cheap BUT they work.
Thanks for posting this again, I did not know that. I've just been mindlessly sticking that cheapie on the faucet without regard to actual pressure. My last pressure gauge may still be on a faucet in Montana, but after DW compained about shower power last time out, I bought another one. Will pay a lot closer attention now, and I'm sure will end up with a real pressure regulator.
Thanks again.

Have you ever noticed it's much easier to hold a discussion in person than by written word? I sure have.

Some years ago I switched from 1/2" hose to 5/8" hose. The increase in volume of water flow was immediately noticeable. I always recommend 5/8" water hose. If you have high pressure, like 60-70 PSI, you won't need a larger size hose as the results won't be as noticeable. If you are running 30 - 40 PSI you'll notice the difference.

I have purchased 3/4" brass, male and female, hose fittings but the only 3/4" hose I could find (several years ago) was restaurant grade and it was very "dear" in price. If I ever finish this project I'll post the results .

We are on well water here in Maine and the first two years we came here we suffered badly for pressure and volume. That's when I came across the 3/4" fittings, purchased them and was ready to get the 3/4" hose and the owner of the camp ground owner, the next season, made improvements in the water delivery system. Now I run 35 PSI and we can survive. We certainly don't need any flow or pressure devices in the system.

I always check the pressure when hooking up to a new (to me) system.

From a practical point of view, smaller diameter hoses are not normally a problem unless the available water pressure is very small or the hose is really long. The only time you would even sense a difference is when filling the tank, and then it would take a little longer.
I agree with what you have said. I use the Watts regulator and a 5/8 in hose and have very good pressure a flow. There have been times when I have used a 1/2 in hose with the Watts regulator and there is a noticeable difference in lower flow when using the 1/2 hose.

For those of you that would like a recommendation on water pressure regulators, I would suggest using only a household watts adjustable pressure regulator normally found used in a house along with a gauge to see what the actually water pressure is going into your coach. Everything else is a waste of your money and will generally only restrict the water versus reducing the pressure. And with the watts, you can adjust the pressure each time depending on how much initial water pressure the RV park has to start out with.

Regarding hoses, I gave up on the white RV approved hose years ago. However I do own a flat roll-up 25ft. hose that was purchased from CW but have never used it to date. It sits in the basement storage in one of my storage bins. What I do use is a series of 6 ft. stainless steel covered washing machine hoses. One that goes from the watts pressure regulator to my house water filter, another going from the filter to my water softener, then a third going from the softener to my coach. One important thing that I must point out is that we only use the water to wash dishes, shower, the ice maker with extra filtration and for the toilet. We never use the water for general drinking or cooking purposes. The water quality where we are in Santa Clarita, CA is quite hard, hence the reason for the softener, so as a result, we use bottled water solely for cooking, drinking and even for our dog's water dish.

Happy Holidays.

So your using a water softener, why then do you need bottled water???

Dirko is absolutely correct. As my plumber told me when I ran my water line from the city connection at the street to the back of my property which is about 100 ft., he said to run 1-inch PVC rather then 3/4-inch as it would help by not restricting the flow. Smaller diameter restricts the flow. But from the faucet to the RV I'm only using a 10-foot hose so the size makes little difference.

Softener water contains large quantities of Sodium. Plus, the taste is not so nice. I prefer bottled or filtered H2O. Distilled is blah/gag/retch..same with DI (De-ionized) and RO. Best is bottled with a splash of flavored C2H5OH.

The soft water allows us to use less soap when doing dishes and taking showers because the soap lathers up really well with the soft water versus hard water.

I not on a sodium diet but to drink that stuff, UGH! Just the thought turns my stomach. I don't mind an ice cube or two as you really can't tell with the ice, however the bottled water taste so much better. We buy it from a bulk supplier filing up our 2-3 gallon water dispenser jugs usually once a week.

Is bigger better?

As a new member, I make this statement.

This forum goes off subject just like every one I've joined/observed.
No need to get excited, it's as natural as sunshine in Florida.
The real info is in the first few posts, as always.
