Q:i'm being charged $300 to replace a 75gallon water heater valve, is that too much?
What, just the valve? What valve? A stop valve in the supply or delivery line? Or the temperature and pressure valve? There's no way on God's green earth I'd ever fork over $300 for this job. I can do it myself in thirty minutes. The TP valve would take less than ten minutes. Granted I'm a handyman and I have a shopful of tools and 20 years experience. But back in the day, when I'd never done any maintenance work, I replaced my own water heater from start to finish and it only took a couple of hours. Unless there's something major going on that you're not disclosing to us, it sounds like a pretty serious overcharge. [edit] To answer your additional questions, I wouldn't pay that much to replace all three valves. The valves themselves aren't very expensive, and the only really difficult part of this entire operation is getting all the water under control to replace the drain valve. Something's going to get wet, and that tends to make homeowners annoyed and difficult customers. The TP valve is a simple wrench-in, wrench-out replacement. Water off, power off, drain below the level of the valve and out it comes. Control valve requires turning off the house's water, but less draining. Replacing the drain valve requires draining the entire heater but again it's a wrench-in, wrench-out job. Easy.
Q:Radiator valve is constantly spitting water?
Melvin S is correct. But check to see if the valve is closed first.

Q:what are valves in 2/4 stroke engines?
I can tell you right now crazydrunk couldn't have provided the right answer. If he knew what he was talking about, He'd know if the car is advertising the number of valves, and its 16 valves, thats 4 Cylinders, with 4 valves in each cylinder. Two for intake and two for exhaust. The intakes are usually the bigger ones. Simply divide the number of valves by 4 and you'll get the number of cylinders. 24 valve is 6 cylinder and 32 valves is 8. 2 stroke engines are commonly found in old motorcycles, lawn mowers, leaf blowers, genorators and small gas engines like that. 4 stroke engines are found in anything that runs on gas and is over 1000lbs, usually and diesel is above that but runs on heat ignition, rather than spark ignition.
Q:request information deep well foot valve?
This drop tube is the suction line. This tube will always be below the water level in the well. I would talk to a competent water well company and get their recommendations. Regards, Dale
Q:Broke a Bolt in the Valve Cover?
easiest to just remove the valve cover completely and then there might be enough of the broken bolt left to get a pair of vice grips on it and unscrew it out, go to parts store and get a new bolt and a new valve cover gasket and reinstall.If you drive the car the way it is it might leak a little oil around the broken bolt.
Q:What Does It Mean To Need A Valve Job On A Car?
i own a repair shop and what they mean when they say this, is that the head is taken off if it and the valves re-ground,and re-seated,and new seals put on them what this does it re-stores the compression on the upper end of the engine back to where it should be,as long as the piston rings aren't worn out in it,this usually works well,in some cases though it will make an engine start using oil,because it puts pressure on the upper end of the engine,and if it has any weak rings in it,this will make it use a little oil so be careful if you buy this one,keep in mind that a vale job doesn't always help one,it might run better,but can use oil later on ,this happens occasionally ,especially on higher mileage vehicles,and the cost of it would be around 600 bucks ,so make sure this car is worth it before you buy it,good luck with it hope this helps.
Q:Is my Gas Valve faulty ?
There are a few possibilities. The valve runs on a low voltage line. The low voltage is provided by a transformer. It it possible the transformer is bad. Be sure the power switch to the furnace is on. (should be on the side of the furnace. Easy way to check is (on the thermostat) turn the fan switch from auto to run. The blower fan should come on. Check that the gas valve is in the ON position.(if you have had to light the pilot it may still be in pilot position.) Another possibility is a clogged gas line. If you have an older home rust can accumulate inside the iron gas lines. Where the gas line attaches to the furnace there should be a drip leg. This is a short length of pipe that points down with a cap on it from the TEE that goes into the furnace. This short piece of pipe is to catch any moisture or rust that comes thru the line. First TURN OFF the gas at the shut off in the pipe it's self. This is a quarter turn valve. When the handle is in line with the pipe the gas is on. When it is opposite the pipe (pointing out to the side) the gas is off. After turning the gas off, remove the cap from the bottom of the drip leg to remove any accumulation.USE PIPE DOPE not teflon tape when putting the cap back on.Turn the gas valve back on and check for leaks.
Q:Leaky Aortic Valve???
1. okorder.com/.. that will tell you what to do to keep yourself healthy and help keep te regurgitation mild. Thankfully its just a mild heart problem, so you should be fine for many years. Im 16 and i was born with Aortic Stenosis, and a Bicuspid aortic valve, which led me to develop Aortic Regurgitation(leaky) and an Enlarged aorta. I havent had surgery yet, but my conditions are getting slowly worse and in a few years i will need surgery. I go to a camp for kids with heart disease, and some of my friends have very severe heart problems that cause them to get heart transplants, or tons and tons of surgery and some have even died. :( So if you have any questions or anything feel free to email me(go through my profile)
