Q:Around the relief valve there is water leaking it is not the valve it's self or the threads it's around the out side of it. The valve is on top of the heater: close off the chilly water grant to the water heater and additionally close the gas grant or the heater administration. Drain the water heater (this might drain all your homestead warm water besides). Open a warm water sink valve to enable air enter. Drain the water till the water is below the threads. decrease or unsolder the joints mandatory to get rid of the threaded setting up. get rid of the setting up, and positioned across it to a community plumbing grant homestead and get a clean one. set up the hot one with teflon tape. close the sink warm valve. Open the chilly water grant valve on the water heater slowly. verify for any leaks. If its leaking, initiate over. If not resolder the copper joints jointly, and be confident to purge the air by way of your sink back. or in basic terms call a plumber or an HVAC business company.

Q:I just got my trumpet today.And its playing fine.Now its not playing.When i play im blowing air into it but its not going through.Its like im trying to blow air through solid meatel.and everytime in blow into it.The slide with the ring on it (sorry i just got the trumpet,im not really sure what the parts are) it keeps falling off.Its like its waay too loose.Help please: instead of the standard cheapo trumpet grease, try a more generic brass instrument oil. also make sure you aren't tightening the valve screw cap too tightly. it's not a good idea just keep tapping it. also, unwanted moisture can create a seal that will sometimes inhibit the valve from popping back up. get it dried out as much as you can. also, don't use too much of anything - the oil, the grease, etc - excess will keep it from popping out too.

Q:i have got a problem with the valve but i have some guy gonna try and clean it next week. i have heard of blanking plates. has anyone used one of these? do they make any difference in the way the car goes ?: Ford Mondeo Egr Valve Problems

Q:I gotta 89 Crx si. Just wondering if you could put on a blow off valve and it work without it boosted: you can put one on but it wont work.... BUT if you want the whole turb whistle sound you can buy one of those turbo whistles you can put it on the end of your exhuast and it will make that turbo sound but no BOV

Q:i wanted to know what is the actual difference between check valve (non return valve) and globe valve?: Check valve/non-return valves are unidirectional, meaning flow can only go through them one direction. Check/Non-return valves usually don't include any kind of manual actuation. Globe valves have a sphere with a hole cut through it, as the globe is rotated within the housing, the hole aligns with the valve inlet and outlet, or is sealed from the inlet/outlet by the valve casing. Thus, the handle/knob is used to rotate the ball, thereby opening or closing the valve. Because the hole is cut cleanly through the ball, flow through a globe valve is bi-directional.

Q:What is the easiest and best way to fix a leaking shut-off valve on a toilet?: Replace it there fairly cheap.Usally all you need is a wrench an pipe thread tape and a new shut off valve bably less than 20 bucks total.Just turn off the water an flush the toilet.Place a pot under the connection so it will catch any remaining water as you loosen the connection.There are 2 large nuts at each end of the shut off valve.Turn them conter clockwise to loosen an clockwise to tighten.Wrap the threads with pipe thread tape on both ends before installing the new shut off.Its probably one of the easiest do it yourself plumbing jobs there is.Once you have the new shut off installed an tightened turn the water back on an check for leaks.If it is leaking you may have to tighten your connection a little more.Good luck,I hope this helps.

Q:I think the piece leaking is a valve;it is one solid piece of copper with two tubes, one which is a half inch that connectsinto the incoming hot water and then a small outgoing one that connects to the faucet and I don't know how to find a replacement part .. I think it is a Delta but I am not sure ... the house is 10 years old but where can I just find a valve instead of replacing the entire faucet if I don't know what the make or model is ?Any websites with pics of replacement valves for Roman Tubs??: Remove the valve and take it to a plumbing supply store. Home Depot and the like may have what you're looking for; but you're more likely to find it at a plumber's supply. They are the only ones I've ever found who carry odd bits.

Q:Where is the Canister vent shut valve located on a 2003 honda crv: The canister vent shut valve is located in the evap canister. Rarely do we have issues with these. Usually we have issues with the 2 way valve or the bypass valve. Based on the age of the vehicle, the dealer would recommend replacement of these 2 valves as well as the canister. The reason for this is over time, when you fill the vehicle with gas, you try to top off the tank. The fuel winds up being pushed into the evap valves and the canister. This liquid gas causes the sensor to read wrong which results in this code.

Q:I was considering making a ball valve PVC air rifle or something of the sort using a PVC air canister and a hand pump, but I wanted to know about it, last year I made one that was air tight but air leaked out of the top of the pump which really annoyed me, I looked further onto the it and found out that there was a Bike Tyre valve, What does it do? Does it let air flow in but stop it from coming out? and where would I find some good designs as well as the items needed to make it? And don't bother answering 'Buy an air soft gun' because Australia does not retail those.: hi there in canada , at any big truck tire repair place they have tire valves that are like bunker fittings, that is to say a valve that has a threaded bottom end with nuts and rubber washers, you would drill the appropriate size hole in the pipe and put the valve through and tighten the nuts up against the washers making an air tight seal, that should work for you if they have them in au, good luck

Q:Chev 350 in marine use. Made horiffic exhaust noise, especially with increasing throttle. Cam seems fine still, but the rocker on #5 exhaust was somewhat off to the side but still touching the side of the valve stem...but stem bent. What would cause this and is this the cause of the loud combustion sound (like a spark plug out of it's hole?: that would be caused by high rpm with no load, had it happen in my car years ago, well before i acquired it. vacuum modulator line cam off, car was driven home for about 15 miles at normal speeds (OUCH, 45 in first gear in a 68 gto) bent 4 rods and some other damage that i do not remember.
