Q: I have checked this and ensured that the flow control is turned on. I have also found that:1. Valve works in manual mode2. Solenoid is getting electricity and water seems to be flowing in automatic mode but nothing is coming out of the sprinkler.I am not sure what could be broken as manual operation works and solenoid sems to be working. Any ideas?Thanks.: Toro Irrigation Valves

Q: It's filling up a 5 gallon bucket roughly ever 9-10 hours. It was leaking with an old valve and has been replaced, and after being replaced it didn't stop. The temperature has not been adjusted higher or lower, it's exactly where it was for the year before the leak started. Any ideas?: Instructions : 1 Shut off the power to water heater. If electric, turn gas to pilot setting, if a gas water heater. Cut off water supply to water heater as well. 2 Drain the water from tank to just below relief valve. It is not necessary to drain the entire tank. Open a hot water faucet, drain tank from tank drain for approximately three to five minutes. 3 Prepare the new relief valve with Teflon tape. Remove the dip tube and any other connections to the relief valve. Check faucet to make sure water is not running. A slow drip is OK. 4Unscrew the relief valve counter-clockwise with a wrench to remove. Install the new relief valve. Install the dip tube with a compression fitting, if you had to cut it to remove earlier. Make all other connections. 5. Turn the water supply back on to water heater. Make sure water is running from the open faucet before turning the power back on.

Q: In my condo, I have what appears to be a water relief valve of some sort right after my water inlet pipe. It's after the water cutoff valve. It's not the water heater relief valve. It has a leak, not bad, just a drip right now. It looks like a half baseball sticking out of the main inlet pipe with a bolt in the center of it. I've tried to tighten it but that makes the leak worse. First, what is this. Second, Is there an obvious fix to this. Third, if I have to get it replaced, what model/manufacturer can I get so that this doesn't happen for a long while. My plumbing is short of fifteen years old.: It sounds like a cold water relief valve, also known as a thermal expansion valve. It leaks when your city pressure exceeds 100psi (factory setting) or the set pressure. Code requires pressure to be below 80 psi. A Watts 530C will do the trick. It is adjustable. It will cost you about $30.00 - $40.00 + labor to remove old install new. If it is a pressure reducing valve, a new one will cost about $125.00. It lowers your pressure when it exceeds max allowable per the plumbing code, 80 psi here in Florida. I use the Watts 1 25AUB-Z3 Pressure Reducing Valve for these applications and set it at 60 psi.

Q: I wanna do it myself My dad knows how But i must buy the parts I have a rmz250 and i was wondering if u can jus buy valves and seals and jus put them in without grinding since the seals are new i heard u must gring the seals to get the valves to sit flush againt the metal serface but cant u jus buy new seals and retainers and put that in plus the valves and ur done?: you *can* just put the valves seals in and run it but it is NOT recommended. If you want the best seal which will = the most power, the valve seats need to be cut. If your not running a titanium intake you could get away with just lapping the valves with course and then fine lapping compound. I know a lot of people who just lap them in, but the most professional way with the best results is to cut the seats.

Q: I am wondering if i can put a blow off Valve on my Crossfire and still get the same sound as if it had a turbo. the car is stock and i just got it so i do not know if it does have a turbo already. Can anyone help me with this.: Doesn't have a turbo regardless of whether it's the 4 cylinder or v6 engine. EDIT: Blow off valves work by purging boost pressure (from the turbo) from the intake piping before the throttle body. Meaning, without a turbocharger there is no build up of pressure prior to the throttle and hence without a turbo a blow off valve is functionless (and it WILL NOT make a noise).

Q: I had to replace the seat washers/stems etc in order for the constant drips from the kitchen faucet to stop. It did; but when i went under the sink to turn the water valves back on, the hot water valve felt as something inside it went smooth??? i can turn the hot water valve left and right but nothing is happening. No hot water at all from the kitchen faucet..Also there's low water pressure from the cold water that only came about when I tried to turn the hot water back on from the valve underneath the sink: Unfortunately most valves used today are made of plastic that only look like metal on the outside. Sounds to me like you and I live in the same house. I have to replace four different shut off valves because they are stripped. I am working on the kitchen one right now. Stripped Valve with no cold water and very little pressure in the other valve. If you ever have one replaced by a plumber, insist on all metal valves. I will physically inspect them from now on before they replace them. Once stripped nothing you can do but put a new one on.

Q: Offcourse temp control valve controls temp, and pressure control valve controls pressure....and so on. I am wondering, what are the mechnical differences in the valves body and how are they operated in terms of process control.: There okorder /

Q: This is my first tranny install and there is one thing that i really think i f'd up on. I'v been installing a junk yard 700r4 and transfer case into this beater 1990 k1500. Everything is in i'm just waiting on a new throttle valve cable (detent cable) to put it. But me, being my first tranny install, thought that the piece inside of the transmission that the detent cable attatches too.....came out. which i later found out that it doesn't, and that the TV cable just connects to it. I yanked on it pretty good with some pliers, and it never came out, and it still moves up and down. My question is could i have done some serious damage to that peice and the throttle valve itself???? let me know what u think.... thanks!: The only thing i can think you could have done i bent the peice that comes out of the trans. If the throttle valve still returns like a spring when you pull it with your fingers and you can still hook the tv cable to it it should be fine. unhook the tv cable at the carb or throttle body to hook it to the valve then hook it back to the carb or throttle body.

Q: Can a leaking car tyre valve be repaired/ replaced, or is it more viable to get a new tyre fitted with a new valve?: you just need the valve itself changed...its nothing to do with the tyre as the valve is bolted to the wheel not the tyre...
