Ruud Hot Water Heater

I have a Ruud brand hot water heater. About a month ago, I noticed a small trail of water coming from the bottom of it and leading out of the garage (a very small trail). I opened up the two little panels on it and the top one had alot of water in it. I thoroughly checked the outside of the heater and didn't see anything out of the ordinary. We were leaving for a cruise the next day so I just turned off the valve to it and shut off the breakers to it at the box. When I came home a week or so later, I turned it all back on. It's been 2 weeks now and there is no leak and it "seems" to be working ok. Should I replace it or is there an explanation for why it was leaking water? (sorry this is under air conditioners, but I counldn't find HWH in any of the lists)

    I own a RUUD Hot water heater. It is currently leaking water from the bottom. There are no indications of water in the lower access panel.

I suspect there is a leak in the tank and because you shut it off for a period of time, the hole sealed up with rust. If the heater is under warranty, contact your installer and show him the water spots inside the jacket. It should be covered under the warranty. If it is out of warranty, replace it before it does damage to the surrounding areas. If you let it go a while, get yourself a moisture alarm and put it next to the unit. If it should leak again, it will not stop until someone turns off the water valve. \\Good Luck!

Hello Marcia

Unit is probably rusted out:
http://waterheatertimer.org/Leaking-water-heater.html

Reliance is AO Smith. I recommend the AO Smith line-up of water heater brands as best because air intake screen is located on bottom of unit and can be cleaned by homeowner without removing combustion parts, and because AO Smith posts service manuals.

Water is found leaking at the bottom of the tank, near the plastic cap, at the centre of the tank. What actually happens and how to resolve. The heater has been installed more than 5 years ago. From the...
A) Calculate date of water heater manufacture from serial number located on side of tank:
http://waterheatertimer.org/pdf/WaterHeaterSerialNumberDecoder.pdf
Date of manufacture is not date of installation.
Warranty is usually from date of manufacture
Serial number also shows tank size in gallons, tank volts and watts, and whether tank has 1 or 2 elements.

B) Troubleshoot leaking water heater:
http://waterheatertimer.org/Water-at-bottom-of-water-heater.html
Several things can be looked at to see where leak is coming from.
Carefully go over tank pipes and valves to eliminate every suspect.
Final suspect: tank is rusted out.

C) If tank is rusted out, then tank needs to be replaced before it ruptures.
Ruptured tank can cause major damage and water runs until shut off.
To prevent rupture, turn off power to heater, turn off valve located above tank, open tub faucet for a moment to relieve pressure on tank.
Turn on heater only when needed until new tank is installed.
4500 Watt water heater produces 21 gallons hot water per hour.
Shower uses 6-9 gallons hot water. Bath uses 12-14 gallons hot water.

"It is possible to limp along with a failed water heater if the leak is slow and if you turn off power and water when not using hot water. That trick could buy time, possibly up to 3 months. With time, you can consider how to make the system do more for less as well as comparison shop, get competitive bids, etc"

D) Now you're home is safe from damage.
If tank is only 5 years old, it rusted out pretty quick.

There are three things you can do so next heater lasts longer.

1) Learn about anode rods, and inspect anode rod every 1-3 years.
Loosen anode rod before installing new tank so replacement is easier.
http://waterheatertimer.org/Replace-anode-rod.html

2) Attach electrical ground wire between hot and cold pipes to prevent stray current from reducing life of water heater
http://waterheatertimer.org/9-ways-to-save-with-water-heater.html#straycurrent

3) Flush tank each 6 months to prevent sediment

Hot water tank does not work when shower is on, it does however work when the faucet in bathroom is on. It quit working in the shower about a month ago.
  1. COLD MIX, HEATER DEACTIVATES
    If inlet water temperature is over 70°F due to geographic location, water maybe very hot out of the tap. This requires a lot of cold water to be added with it in order to attain a useable hot water temperature. The addition of too much cold water will overpower hot water demand from the tankless water heater. This slows the flow within the tankless water heater, decreasing it below activation point, which shuts off the heater. The end result is nothing but cold water coming out of the outlet. See: TWH E2-04 Overcoming fluctuating temperatures [PDF].
  2. FLUCTUATING WATER PRESSURE
    If the water pressure in the home is erratic and the water flow is not consistent while a tap is opened, then the temperature of hot water will fluctuate. The minimum water pressure for the home should be 30psi or greater. For people on well systems the minimum pressure range is 30-50psi. The use of a pressure reducing/regulating valve is an effective way to maintain constant water pressure to the water heater. Watts brand 25AUB- ¾" or N35B-¾" pressure reducing/regulating valves or equivalent is suggested.
  3. CHANGING FLOW RATE
    Major changes in flow rate can adversely affect the output water temperature of the heater. Increases from one major fixture running to multiple fixtures running at one time can cause the temperature to fluctuate. Stay within the heater's specifications. See: TWH E2-03 Outlet temperature vs. flow rate [PDF].
From the Bosch website.

Little amount of hot water
Quite likely a bad element. There are two in electric HW heaters. Often the bottom one will fail so you only end up with the upper half heated up.

You can check it with a digital volt meter if you have one.

with the power off at the breaker box, you can remove the wires from the element and (using the ohm (resistance) setting) check across the terminals. it should read around (4500W/240V = 18 ohms).

How old a HW heater? might be time to replace it...

Not enough hot water to complete shower. Noticed
If it is a new water heater it might be that the water supplies are crossed. The cold water should be installed on the right hand side of the tank or on the bottom if your tank hooks up on the side. If its an older water heater the dip tube may have broken off. This is a tube that runs from the top of your water heater on the cold side to the lower portion of the tank.It puts the cold water in the bottom of the heater which pushes the hot water to the top.To change the dip tube out you must disconnect the cold water supply from the 3/4 inch nipple at the top of the tank. Then with a pipe wrench unscrew the nipple from the tank it will have the remainder of the tube on it.You can get a replacement dip tube at a plumming supply. Installation is opposite of removal. If this is your problem I suggest you get a new water heater .Usually its caused from minnerals in the water or buy two dissimiler metals being connected together in the water piping system causing corrosion Your water heater will probably fail in the near future.

I had our 1600ng Bosch water heater installed a month ago during warmer weather. It is not providing very hot showers. I use all hot no cold. how can io get more heat
