Water heater pressure is very low

Problem with Rheem 40 GAL ELEC TALL Water Heater 6YR SC 82VH402


MY HOTWATER PRESSURE IS VERY LOW WHICH IS MAKING MY HOTWTER COME OUT VERY SLOW ALL OVER THE HOUSE. THE COLD WATER RUNS AT A VERY HIGH CONSTANT SPEED. SO HOW DO I FIGURE OUT WHY THE PRESSURE FOR THE HOTWTER IS SO SLOW.

Close the valve that on top of the water heater on the col side on due the hot side house, and screw in a 3/4gage valve on top of heater then open the valve the one you close and you will read the pressure on the gauge ; you'll know if is your tank is clog you could have at least 50 psi on you're gauge.

The link above goes to professional plumbers.
They will know and see more things than I can short-list for you.
They will probably tell you to take apart the lines going into water heater to see if problem is before or after water heater. Or if the problem is inside the water heater.
The problem might be at the shut off valve located on cold water line going into heater.
If you have hard water, the problem could be at an elbow.

rheem water heater Not enough hot water,running out

Problem with Rheem 40 GAL ELEC TALL Water Heater 6YR SC 82VH402


Not enough hot water,running out before I'm finished showering.



Hello,

Hot water heaters are a touchy thing. There performance depends on your demand. If you are using an energy saving shower head I would expect you to have enough hot water for easily a couple of showers. But, if your using the "power flush" type shower heads that use 3.5 gpm or more, the 40 gallon heater is not enough. Also, consider type of water your heating. Is it well water or municipal. Unsoftened well (this includes some municipal well supplies too) water causes hardness ions to cake the heater element making them less efficient. If you have the low flow shower, it is likely you have an element burnt out. They can simply be replaced and picked up at any big box store for less than $20 dollars. Each element can be tested in place with a continuity tester. If your not sure how to test, but would be willing to replace the elements - replace both of them. You will have to shut off power to heater and drain tank completely before removing elements. Replace elements with same wattage or higher. Most have two 2250 watt elements for a total of 4500 watts. you can easily install two 3000 watt elements and have a quicker recovery rate and more hot water than ever.

If it is a 40 gallon tank,. and has the potential to produce plenty of hot water. then drain out the hot water tank! it may have a lot of scale build up in it. a water heater has to be drained at least every year or so. but that depends on the quality of the water going to it. they say its a good practice to drain out a few gallons every 6 months, to ensure it is clean. but i have a 40 gallon tank, and it has been in for about 5 years. no problems. but the water going in is real good. just hook a hose to bottom drain, and run out a few gallons till it appears clean or all sludge is out.

How to drain71- 40 .where is drain need to replace hearer need to drain first. 50 gal



Solution 1:---
There is usually a spigot right at the base of the water heater. Thread a garden hose on the spigot and route the garden hose outside. Of course be sure to pull the power breaker first. After you are sure that the power is off, turn the spigot handle and let the water flow. Be sure that you turn the inlet valve off that is located on the top feed pipe. Be sure to turn the feed back on before you power up as this will ensure that the upper and lower calrods are covered before you power on.


Solution 2:--
1. Turn off the breaker at the panel box, it should be marked, " Water heater," or WH.
2. You should be able to find a spicket on the bottom.
3. Connect a standard garden hose to the spicket at the tank and run the other end
to the location you want to drain the water to.
4. Turn the spicket handle to the left, " counter clockwise " to allow the water in the tank
to start draining.
5. On the top of the tank, in the center, you should find a pipe, and on the top of the pipe
there should be a little tag that says, " pressure release valve ", use your fingers to put
this small metal switch in a straight up position.
