Step 5: Install New Valve Use the Teflon tape on the threads of the new valve. I did set the water heater to the Vacation setting. This will help to form a more cohesive bond with the threads. You might want to have the utilitiy company or a home inspection service check your water pressure both hot at the tank and cold at a faucet outside. Contact a plumber to inspect the unit, as you may need to replace it. Also, the outside temp is dropping around here.
A couple of months ago, our gas water heater started leaking from the top. If the threads around the valve are still leaking after sealing them, there may be a problem with the threads on the relief valve opening in the water heater, and you would probably need a plumber to fix it. In some cases, you may need to replace the entire water heater unit. An extremely small drip has developed at the end of this copper tube at the drain pan at the floor which over time begins to fill the drain pan. A new pressure relief valve is not expensive and easy to install. Turn off the cold water supply to the water heater.
There are two things that can be done with the valve. Turn off the hot water faucet you opened earlier. There are a number of good companies that have professionals working for such tasks. My 11 year old gas water heater is leaking heavily in the pressure relief valve since this morning. When in the middle position, water runs freely from the valve. Thread the connector into the relief valve discharge opening and tighten it with a wrench. Try asking — he does a Fix-it-Friday on his facebook page, where he answers your plumbing questions every Friday.
In this instance, it is probably best to contact a plumber to have a thorough cleaning of the system and if necessary replace the relief valve. Only six philips head screws and the baffle was removed. The water does not come on the outside of the valve, but inside the pipe. Does the requirement to increase the setting indicate an issue, will opening the pressure valve help? Even if the valve is cold it still run and have a lot of pressure. In an event of a return, coupon savings may be deducted from your refund. A friend of mine had told me not to keep waiting as she has heard of tanks exploding.
With the outlet tube removed you can take out the old pressure relief valve. There should be no obstruction between the valve and tank. I didnt turn anything else off but the gas and delmarva told me how to do that. My husband is thinking that maybe our problem is because our swamp cooler shares the water line with the water heater but the water heater leaks from too much water pressure the second i turn the water on. I have had salesmen tell me that it is a waste. I too have a question. Last night I actually had steam visible coming out of my faucets.
We just replaced a 19 year old water heater that dripped just a bit from the relief valve. But it was too late to go back to the store. I have not touched thermostat or water psi yet. You don't have a lot of choices here. Today the water is pouring out of the discharge tube.
A 40 gal tank should release about one half gal on each heat cycle. We have been in the home for 11 years and prior to replacing the valve I performed zero preventive maintenance I did not know it was required. The entire tank doesn't need to be drained. Should you choose to undertake repairs or maintenance, you are assuming the risk of injury to your person or property. Or it could be a sign that the pressure relief valve itself is not closing properly, in which case all you need to do is replace the pressure relief valve on the water heater.
Or will a slow drip at the relief valve be acceptable to home inspectors? It has been so intermittent I actually had to put a plastic cup under the pipe to make sure that is actually where it was coming from. When we tested the water pressure it was between 80 — 110 psi. What can I do to prevent this? So whatever caused the water pressure to get too high after it is fixed, replace the relief valve. Be prepared for water to begin pouring out of the valve hole once the valve is removed. All of us do that from time to time, can we blame the valve? At this time you can call the plumber or you can repair by yourself if you finds the leak. Is this a new plumbing code? Also, I noticed that your illustration shows the expansion tank before the hot water heater shutoff valve…most of the illustrations seem to stress it should be between the shutoff valve and the cold water nipple. Leaking If water is just dripping from the pressure relief valve pipe, it typically means that the system is working properly to release overly hot water and reduce pressure in the system.
