You would need to remove the inlet water valve, the screen is just past your installation point

I have a Whirpool water heater Model No. E3z5ordo55cv the T&P valve is leaking I have replaced it twice in the past week. It is still leaking. Any suggestions ???

The T&P valve or temperature and pressure relief valve is placed on a hot water heater for safety. If it is still leaking after replacement either the temperature is too high causing excessive pressure or your house pressure regulator is set to high or has failed. The water heater has a thermostat to control the temperature. Check to make sure it isnt cranked all the way up. If the water heater is old there could be a lot of sediment build up. if sediment builds up near the temp sensor it will have to superheat the water above normal levels to heat the sediment up enough to shut off. Drain your water heater and flush out all the junk then try it again.

MY Rheem 81SV40D Water Heater (47 gal) does not heat enough water. Approximately one bath worth.

You have dual-element 240Volt electric water heater.
Since you have some hot water, then we know upper element is good, and that circuit breaker and electricity to water heater are good.
Not enough hot water is probably bad lower element, and possibly sediment build-up in bottom of tank.
Test element:
Replace 4500 watt element available at local hardware, and clean out bottom of tank:

Vanguard 50 gallon electric hot water heater only enough water for about 2/3 of a shower. Used to get enough for 4 showers. Had elements and thermastat replaced. Circuit breaker checked ok. No leaks -...

Replace overflow valve to end the drip.

If tank type water heater has some hot water, then upper element is receiving 240V and electric circuit can be eliminated as suspect.
Lower element or shorted wire to lower part of tank or upper thermostat not wired correctly are next suspects. If plumber replaced the parts the wiring will be correct, but he may not have checked for shorted wire.
If the elements were replaced but sediment was not cleaned out of tank, then that can also cause the problem you describe: the new lower element is shorted out because its stuck in the sediment or no water is circulating around the new element.
Open following links for details how to test and clean tank and test elements:

Not enough hotwater cant take afull shower ive replaced elements &thermostats iset them at140 degres its a 40gal.

I suggest a complete troubleshoot:

The fact that you get some hot water says upper element is working and tank is receiving 240V.
So circuit is not suspect, and new upper element probably reads correct ohms.
That leaves 4 suspects: upper thermostat, lower thermostat. lower element, loose or broken wire located between upper and lower parts of tank.

It is possible to replace lower element and not clean out sediment, so water is not circulating around element, and lower element is not really doing much of a job.

Enough hot water for 1 bath. Replaced upper and lower elements and replaced both thermostats. could it be a sedament problem? heater is 5 years old. I never ran out of hot water before now.

You have 240Volt Marathon water heater.
These heaters have element burn-out problems.

Yes sediment can cause decreased amount of hot water when water cannot circulate around lower element, and sediment can cause lower element to burn out.

Following list is overview of tank troubleshoot:

If you have some hot water, then that says several things:
-Upper element is working.
-Electricity from circuit breaker to upper thermostat is good.
-ECO reset button is not tripped.
-You do not have overheating event.
-Access doors and insulation are in place and thermostat not exposed to cool temperature that causes overheating.

That leaves following suspects:
1) Check if TP valve is stuck open, or pipe cracked, or faucet leaking and running hot water down a drain.

2) Upper or lower thermostat is bad.

3) Lower element is bad -and- maybe tank has built-up sediment

4) Loose wire. Open covers and inspect. Tighten screws very tight against copper wire.

5) Bad wire between upper and lower sections of tank.

6) Do complete 30 minute troubleshoot before replacing any parts.

Recently had a sediment problem with our well, is there another place to clean out sediment other than the screens at the hot & cold water hose connections on a whirlpool duet washer?

Hi and welcome to FixYa,
1. Drain and Flush your HOT water heater. This bugger will keep supplying sediment for weeks!
2. There can be hose screens installed at the wall connection also. Remove the hoses and check for hose screens.
3. Check the Inlet screens again.
4. Of you have a pressure tank.. Drain and purge (another source of debris)
Other than that as far a water supply those are the only places to be concerned about. Once your sure you have clean water.... re-check you inlet and hose screens once a week for a while as sediment will migrate through plumbing for extended periods depending on the type of sediment.
The screens can repeatedly clog for some time due to sediment.

If you experience a symptom that your machine will fill when off or leak water by constantly the debris has blocked open the inlet water valve needle at the diaphragm.
- You can sometimes back flush this by first removing BOTH inlet water screens from the water valve and reconnecting the hoses.
- Only connect ONE hose to the wall and turn on the water to the connected hose while placing the other hose in a bucket.
- Select WARM wash and let water flow into bucket. Tap the hose connections with the HANDLE of a hammer or screwdriver in an attempt to loosen debris.
- Reverse hose connections and repeat.

RE-install the inlet screens in the water valve and return the machine to normal use.

Thanks for choosing FixYa,

Not heating enough for one full shower

Is this gas or electric heater?

Gas heater, the thermostat might be bad.
You might need to change out gas valve.
Also look in and see if flame is light blue or yellow.
Blue is good.
Yellow flame means you need to clean burner, or replace burner.
Burner should be cleaned each year.
Refer to manual for instructions and parts list.
Also tank might be filled with sediment.

Electric water heater is different altogether:
Some hot water means upper element is working.
Water heater ECO reset button is good.
Tank is not overheating.
Electricity and circuit breaker are good.
Remaining suspects:
Thermostats are bad, loose wire, shorted wire, lower element burned out, sediment inside tank.

I test instead of guess:
Here is 30 minute troubleshoot overview that will identify problem and show how to repair electric water heater.

Lost hot water pressure

Why do you suspect sediment from the hot water heater? There are no screens to clean before the faucets, so if you are getting sediment it should show up in the shower head screen. How is the water pressure at the shower while you have the head off?

There should be a sediment valve on the hot water heater (down low) that you are supposed to open once-twice a year to flush out the sediment at the bottom, however I suspect that you probably have a build-up of hard water deposits somewhere along the line. There is also an anode rod inside the water heater that wears out over time and must be replaced. The harder your water, the faster it corrodes. Once it is gone, the corrosion moves on the the heater itself - usually at the junction of two different metals.

The anode is accessible on the top of the heater, but the heater must be turned off and the water supply shut before checking the rod - best to have a plumber do it if you haven't done it before. If the corrosion is too bad, you will need to replace the water heater itself.

Washer filling with water after cycle

My oppinion, if it is filling with water after the cycle, replace the valve. The screens are to prevent sediment in the water from getting into the valves. If you try to remove the screens, you will likely dammage them and allow more sediment in. Enough sediment will allow the valve to stay open far enough to over flow the machine.
