Yes this is definately the cartridge.You might not have to replace the cartridge.First take the cartidge out and see if their is any dirt causing the water to pass thru the spout.If thiers nothing obstructing the cartridge than you will need to get a new one.

Hi my vulcan gas hot water service isn't getting hot enough anymore? please help me?


check first if you have good water flow to and from heater. lift pressure release valve on inlet and allow few sec to flow, same with outlet hot water safety valve.

remove front cover from the heater, you should see your gas connection and thermostat knob.

check if gas is burning evenly and on whole surface, check for leaks on the heater and on the lines to and from the heater.

if you did not find any faults, no leaks, safety valves work correctly, check thermostats settings,

wind it down to minimal, then turn it to about 1/4 value (you did not specify model but this should do, widening arrow or numerical values ar self explanatory), lift hot water safety valve for few seconds, then open any hot water tap (faucet if you are an american...) and check if gas ignites and burns.

set thermostat to about 2/3 value and again, lift hot water safety valve for few seconds, then open any hot water tap. check if gas ignites and if water is sufficiently hot, if too hot - wind it down to say 1/2 way, if too cold, wind it till resistant and then back off a bit, DO NOT EVER LEAVE VALVE OR THERMOSTAT ON MAX!.

if none of these help - you need either, change the thermostat or heater itself.

if works - you solved the problem, close the tap, close the cover and use the system as you normally do.

i am always recommending use of insulation on the hot water system, it saves heaps of money over the life of the system.

hope this will help you - do not forget to vote... :-)

Why does my hot water go hot and cold on my gas hot water service


When water feels cold at tap, check water heater TP valve and drain valve to see if water is hot at top and bottom of heater
Maybe you have bad single-handle faucet cartridge

Another possible cause is bad dip tube

Water meter is ticking away. No sign of water or


If you have a gas hot water heater, water may be dripping onto the baffle plate at the bottom and vaporizing whenever the burner fires. There would be no evidence of water under the heater in this case. Yes, I speak from experience. Also check exterior sill cocks for leakage as one might be open just a tiny bit. If you wait for freezing weather, a leaky sill cock will grow a "beard" of ice.

The water heater red light keeps flashing rapidly on my Powervent 2 model 41VRP40N. It is not producing hot water and when I read the manual it says it needs more heat. What does this mean. How do I fix...


There are many things to check. The single most important test is for 24V at the gas valve after the ignitor is supposed tp be on. 19 V or less and there is either a bad ground or the ingition control board has failed. (Wire ground problems are a high probablilty)

Here is what the book says:

PROBLEM #1 - HOT SURFACE IGNITOR DOES NOT GLOW RED

(Remember to wait for purge time, 17/34 seconds, on models so equipped).

Possible causes

A. No main power

B. Faulty transformer

C. Faulty thermostat

D. Faulty limit switch

E. Faulty blower interlock switch

F. Faulty hot surface ignitor

G. Faulty ignition control

Solution

Step #1

Perform normal system checks of main power, transformer, thermostat, limit

switch, blower interlock switch, and replace faulty component.

Step #2

With power on and thermostat set at its highest position, check voltage

between "TH" and "TR" on HS780 ignition control. If 24 volts is not present

check output at transformer. If no, replace transformer. If transformer

checks out OK look at other controls in the 24 volt circuit I.E.: thermostat,

limit switch, blower interlock switch. Check for 120 volts between "neut"

(L2) and "120" (L1). Check for 120 volts at the ignitor across "IGN" and

"IGN" terminals on the HS780 ignition module. If 120 volts is present,
replace ignitor. If no, replace the 780 series module

PROBLEM #2 - IGNITOR GLOWS RED BUT MAIN BURNER

WOULDN'T LIGHT

Possible causes

A. Improper ignitor alignment

B. Faulty ignition control

C. Faulty gas valve

D. High inlet gas pressure

E. Polarity reversed

F. No earth ground

Solution

Step #1

Check for availability of gas at gas valve. Make sure the manual valve

upstream of the gas valve and the gas valve are in the full on position. Also

make sure gas is being supplied to the system at the proper pressure, too

high will lock-up the valve.

Step #2

Check proper polarity of "NEUT" and "120" on the ignition control by reversing

the wires, if reversed gas valve will not open. If this does not solve the

problem, replace wires as they were.

Step #3

Check for proper ignitor position.

Step #4

Check for a good earth ground by using a meter connected between L1

and furnace chassis. Should read 120 volts, if no, check and/or repair ignition
ground wire or ignition control mounting screws.
CAUTION POLARITY MUST BE OBSERVED

Step #5

Check for 24 volts at the gas valve terminals; "1" and "2" on a 7200 series,

"M" and "C" on a 7100 series, "TH" and "TR" on a 7000 series. If yes,

check wire integrity or change the gas valve. If no, change the 780 series
ignition module.

That is pretty much all of the troubleshooting required.

Thanks for choosing FixYa,
Kelly

For the main gas valve to come on several conditions need to be met.

The system must detect a pilot light prior to turning on the main gas valve for systems with a standing pilot light (not sure what your system has) and on systems with auto igniters (spark or ceramic heat glo) the control board must detect a flame present at the main burner a few seconds after the main gas valve turns on.

The other condition that must be met on systems with power exhaust systems is a vacuum/pressure diaghram switch must be made and stay made telling control circuits that vacuum/pressure is present = power exhaust fan is on and working.

From your description it sounds as if you may have a dirty/failing flame detector (thermocouple). Remove it and give it a good scrubbing with a scotch brite pad etc. cleaning off any carbon or corrosion/gunk re-install and try it out, or simply spend $15.00 or so and install a new one to be sure. The thermocouple is the metal thin tube that protrudes into the pilot and/or main burner flame and is connected to the main gas valve by a thin capilliary tube.

To check the vacuum swich on the blower a multi meter across the switch terminals looking for a steady "state change" as the blower runs/stops will work.
