from main pipes to water softner




Hi again :

Need to install a water softener to the mains (whole house water system) basically i need to run the main line to the softener and then out back to the regular pipes connected to the house ... Question : This i believe is my main water in : What is the green and blue valve colors all about and whats the gadget at the top there by the duct with the blue handle ? .. the blue tap runs outside the house to the front garden so i don't believe i need to soften it.

Although there is a uniform color code for buried line flagging, it isn't applicable in your situation. From what I see in the pics you have two water valves and a pressure regulator.

There's no significance I know of to the colors of the valve handwheels. Probably just what the plumber had in his truck. But if I were you, I'd replace both valves with full port ball valves. They have much less flow resistance and thus provide greater flow. Being just 1/4-turn valves, they're also quicker and easier to open or close.

The "gadget" in your middle picture is a pressure regulator.

That big brass valve with the adjusting screw on it, is a pressure reducing valve. The green colored handle may indicate the quality of the valve. Sometimes plumbers use differrent colored valves to distinguish between hot and cold water or whatever they have on hand at the time. They all do the same basic thing. Some are used for certain applications and are of a better quality or tested at a higher standard that's about it. You can't really rely on the color of the handle as they are easily interchangeable.

It is important. I wouldn't remove it, it's there for a reason. You can adjust it. If adjusting doesn't work, it may have to be replaced or rebuilt. Your city has high water pressure and that prv reduces the pressure so your plumbing doesn't break down. IE, supply shut off valves, toliets, washers, dishwashers, pipes, etc.

Are you having problems with your water pressure?

Typical house averages between 50-60psi water pressure which can be tested at any hose bib or faucet in the house.

You have to connect the softener after the pressure reducing valve. Otherwise you could risk damaging your water softener. Reccommend you check the installation manual of softener, and follow the maufacturers installation instructions. Some may have their own water pressure reducers as an option, I don't know. The reason you have a reducing valve is because your pressure must be exceeding 80 PSI. It should be between 50 - 60 PSI. I would check that first.

Jomn is correct prv is there to reduce the street pressure of the water before it enters your system. Plumb your softenr after the prv, as far as the valves there gate valves different color handle doesnt mean anything they are the same..

I'll throw in my .05 here (no more pennies in Canada). The green handle is a whole house shut off, and the blue handle is an interior shut off for a hose bib. Do you have a hose bib on that wall on the outside?

Wish we would get rid of them here in the US as well. It actually costs more than a penny to make a penny.

Yea that makes sense, as it's the first main water shutoff valve coming into the house. Yea, I believe he said in first post, the pipe with the blue gate valve on it runs outside to his garden. I don't see a city water meter either, must be out of the picture frame.

By all means don't run softened water to the garden. It is not at all good for plants. If you keep house plants you may want to consider an indoor spigot on that line.
