This is a result of building as efficiently (cheaply) as possible, and there is almost no need for room valves. First, efficiency: Valves are more expensive than pipe. Extra valves means more labor cost. If the valves are to be centrally located, then more pipe is required because each "zone" will have to be home-run instead of branching off a shared pipe. ...

The Viega Manabloc is an example of a system in which a central valve manifold uses a dedicated tube for every fixture in the house, as alluded in the comment from BillDOe. In some US homes it's not a difficult retrofit to split the house into at least two zones. Typically the water service enters an unfinished "utility closet" space where the water heater ...

Yes, that looks like your main shutoff valve. It's normally the first valve on your water supply from where it enters your house, and typically before the water meter. In my house there is another valve on the other side of the meter that makes it possible to swap out the meter without draining the house. The copper wire is part of our house's grounding....

It would be difficult to install area shutoffs in most residences, since they need to be accessible to be useful. The best case scenario is an access panel in the floor or wall, the worst case is outside the room in an adjoining room or closet. Even more damning is the fact that they would, by definition, be in non-standard locations. I pity the poor ...

Everybody wants to save money Builders and utility companies are not in the business of wasting money, which means the main line will be as straight and as short as possible. This is a big help to you, since it will narrow your search. Walk out to the curb shut off, and look back at your house. Try to determine the straightest, shortest path between the ...

This a common problem with old multi-turn valves. The first thing to try is to tighten the packing nut on the shut-off shaft. Sometimes this will compress the packing enough to stop the leak. Trying to fix this packing while the water is on is very risky. Even with all the water outlets in the house turned on, you will still be seeing 50 to 70 PSI coming in ...

Have you tried gently tightening the gland nut? It's the hex cap under the handle and squeezes some sort of packing against the valve stem. Tighten only in 1/16 turn increments and only if it moves with minimal force. If it acts in any way like it's tight, somebody else may have already compressed the packing to its maximum and no further seal is possible. ...

This is almost certainly from using a "modified square wave" - MSW - inverter rather than a "true sine wave inverter" - the power conversion circuits in AC LED fixtures expect a sine wave input, and the way they behave when fed MSW input is upsetting your inverter. One possible solution, short of "buy a new inverter" (a rather expensive proposition, ...

Turning the water off and on and getting the air bubbles back out of the pipes often loosens up "crud" in the pipes. Some of that crud may be stuck in the sealing part of the valve. Try opening it all the way and running for a while, perhaps removing the aerator first. You might get lucky and have it work free of the valve mechanism. In many cases the "...

I called my handyman, and he told me to first make sure that the valve is open all the way. He said that the valves only form a good seal if they are either completely open or closed. I opened the valve all the way, and the leak stopped.

There are - just not usually in houses Commercial, industrial and multi-residential buildings almost always have isolation valves for floor or unit take-offs and for each "group" of fixtures. What constitutes a "group" depends on the layout of the building. Basically its a design balancing act between the how large an area has to be shut down for repairs or ...

In France it's commonplace. Not only having small shut-off valves for hot and cold, but also to toilet, washer, dishwasher shower and water heater feeds. There's also manifolds near the rising main and off electric boilers, which isolate each separate feed. Possibly over the top, and meaning more potential leaks, but nevertheless useful on occasions. It'...

Yes. Shut off the water off at the street before you try to fix it. Elsewise you will get a big flood. Then put in a ball valve. Ball valves work faster than gate valves, which can come in handy in an emergency. Ball valves last a long time and work even if they are unused for long periods of time.

Yes, all the water will drain from the second floor. It will take awhile because the faucet you're opening probably has an aerator on it which restrict flow and you only have gravity as a flow force. When working on a one story house the pipes, for the most part, are all horizontal so gravity isn't a factor. You can speed up the draining on two story ...

Yes, we typically are recommending 1/4 turn ball valves for valves that are not used very often. This would include sink stops, laundry stop, and main shut off. However each of those requires a unique solution to replace them per circumstance. The hose bibs we would not recommend a 1/4 turn ball valve as ball valves are not designed to be used often and ...

Your problem is very common with old multi=turn valves. The packings in the valve have probably dried out and split or shrunk a bit. Have you tried turning the valve open and closed a few times? If the packings are shot, you will see the leak change a bit in both open and closed positions. You can try tightening the nut around the on/off shaft just a bit. ...

It is most likely related to the inverter that you are using. Some inverters are sensitive to the kind of load that you put on them, and LED bulbs could easily present that kind of load. The inverter might be better behaved if you give it a better load - like a nice 50 watt incandescent light - along with the LEDs, though that obviously runs your batteries ...

I have found on old valves the valve stem separates from the gate. they close fine but then it feels like it is opening but is broke. You will probably need to turn the water to the house off , bleed the pressure off and remove the valve and install a new one.

The item on the left is the steam trap and can not be regulated or shut off. stay away from this item. The shut-off valve is the item with the screw on the top. Turn the nut ccw (counter clockwise), just slightly about a 1/4 turn, then put a wrench on the stem above the nut, I would use a 6" or 8" pipe wrench or vise grips, and try to turn cw (clockwise) ...

Yes it is your main shut off valve. I'm assuming this is in a basement, from the looks. You're good on that. The best experiment to prove this out is to turn the handle clockwise until it stops. This usually takes about 10 turns. The wire attached is a grounding conductor which more than likely goes inside your breaker box .

That looks like a 1/2" copper pipe with the valve soldered on. Definitely check it with a magnet before trying to wrench it off. If it is copper and you are not handy with soldering, you could replace it fairly easily using a valve with a compression fitting inlet: You will have to carefully cut the pipe behind the existing valve, and use steel wool and/...

That's most likely a copper pipe covered in solder. You can try scraping the solder off to see if you get down to some copper to verify. A copper pipe cutter is cheap and easy to use: Get this onto the pipe a close to the valve as you can, tighten the screw until it's snug, and spin it around the pipe making sure to keep spinning on the same location (you'...

Yes, putting the gas service shut-off in the laundry room would be fine (though they are typically found behind the appliance). Remember, this is a service disconnect valve (for maintenance or replacement of the appliance) not an emergency disconnect valve (in the event of a gas leak). The "emergency disconnect valve" is at the meter since the first rule ...

Check the wiring of the fan (after taking the regular safety precaution of turning off the breaker and double checking that the wires aren't hot), chances are that there are 3 connections (besides ground): neutral, lamp and fan. It's very likely that lamp and fan are jumpered together. To disable the fan entirely you can then simply remove the jumper and ...

In general, there's no problem using the main valve. However, if the sink valves are stuck, you might find that the main is also in poor repair. If the main is old and rarely used, you might find that's it's stuck or will become stuck once closed. If the main valve is a gate/globe valve, and it looks old and cruddy. You might want to consider replacing ...

I'm not sure what the first one is, but you're probably right about it being a meter. Around there they're all inside. The second one is the city's shutoff for the branch to your home. You can see that it has a pentagonal nut, similar to what's on a fire hydrant. If you move out or quit paying your bill they use that to discontinue service. They're usually ...

If you turn the supply of water to the water heater off you don't need to drain it , with the supply off you do want to turn the gas valve to pilot or off depending on the type of tank some have electric ignightors and don't have a standing pilot. The tank will be fine. After that I open the lowest taps in the home usually a bathtub if single level then the ...

You are correct, they are indeed quarter turn valves. To my knowledge, there is no way to repair the valve in question. There is an alternative other than sweating copper for replacing the washer outlet box, but it still requires opening up the wall. The alternative being a washer outlet box with sharkbite fittings for your shutoff valves. You'll still have ...

I would leave the pipes at there current length. The reason I would leave the extra length is if you have problems with the compression fitting leaking now or in the future you will have enough space to cut it off and put a new fitting on.

This really depends on the style of home and the floorplan. For example: My previous home was a 3 story town house with a kitchen, utility room, and half bath on the 1st floor and full baths on the 2nd and 3rd floors. As with most modern designs, all of the rooms with water service were stacked over another to minimize the amount of plumbing that needs to ...
