Q:Is there a leak around my home's outside shutoff valve?
Most homes have a main shutoff valve that goes from the street to the lowest part of the house. usually, they may also have another valve from lowest part of the house to the water fixtures. Ur main drain line is usually 4 feet or more away from the supply incoming line. Your home's outside shutoff valve is called a valve for the supply from your city water. It has nothing to do with your drain system. If you see water coming up from that outside shutoff valve, then a professional plumber needs to dig up the dirt around the valve and replace it. Usually there are no fixtures at this main shutoff valve, unless you are talking about an outside valve for a garden hose? So can u pls rephrase your question?
Q:rear proportioning valve?
i got a 97 model van setting out side the shop and i went and looked at it and it doesn't have one on it,what are you calling the rear proportioning valve,it has a block that the lines split off of but not a proportioning valve,let me know if you got some kind of special edition or something,good luck.
Q:The pressure relief valve leaks on my electric water heater...?
First if you follow the correct procedure the pressure is no problem. 1 Kill the power or gas to the heater-very important for electirc elements will pop if not done before water is drained. 2 Hook up hose to drain on the bottom and open it up to flow water outside of home. 3.Open hot water valve on tub and sink to allow water to drain after you shut off the main water supply. 4.Shut off the main water supply and let tank drain for an hour. 5. Use a pipe wrench to remove old pressure relief valve. 6 Pipe dope new pressure relief valve and install. 7Open main water vlve and close and remove water hose on drain. 8Let water flow out of tub and sink for 5 minutes after air has bled out. 9Turn system back on and be sure check for leaks.
Q:How can I fix my noisy tuba valves?
Piston valves normally have cork or felt cushions so that they don't clank when you operate them. You may be able to get replacements at the music store where you get your valve oil, and they may have a repairman on site or on contract who can do a professional referb on your instrument.
Q:96 saturn sl1 EGR Valve...?
to attempt the EGR valve operation, start up the engine and then disconnect the administration hose The EGR valve could open and engine could sluggish or hesitate. If disconnecting the hose makes no difference, the two the hose is leaky/ blocked or the EGR exhaust gas pipes are blocked. in case you intend on changing it your self spray it with wd 40 or a sturdy penitrating oil and enable it soak. and while reassembling it use an anti grab compound on the threads
Q:korky fill valve hisses?
Korky Toilet Fill Valve
Q:Need help replacing the old valve stem for tub/shower to replace with new valve stem?
Check back on your website to see if they have the procedure for removing/installing the new stem. These usually have to be turned to allow them to be removed. You should be able to purchase a tool to help you release it. Also, be aware the old stem could be hard to remove due to build-up and/or torn seals. After you get it our, try to remve and deposits in the valve and then apply a little lubricant to the new stem before you insert it. Be sure the lubricant is compatable with the seals.
Q:EGR Valve question...?
It recirculates the fumes and the air--but a cracked hose is a nightmare if vacuum leak develops--fix it--just get a new hose and happy motoring
Q:Any idea on selecting and sizing control valves?
You'd also need to know design flow ranges, ultimate flow desired, pressure drop acceptable across valve, and the average temperature of cooling water the valve will see or the range it will see if varies much. You would need to decide if you want to use a ball valve, butterfly valve, of a globe valve to throttle the water.
Q:bent valve stem?
Valve stems don't usually bend unless the valve hits a piston. I am assuming the rod that was bent was a push rod. The 5.2 engine is not an interference engine, so a cam timing problem would not cause the piston to hit the valve. I suppose that if you way over reved the engine a lifter could have pumped up and at a very high RPM the valves may have floated causing one or more to strike a piston. Push rods do bend for a variety of reasons, but to have a bent push rod AND a bent valve stem I would need more information to give you even an educated guess. You have the head off so look at the top of the piston and see if it looks like it was hit by the valves. Take the head to a machinist and have him check it for cracks and damaged guides. Have him check the valve spring tension also.
