One way to test a solenoid valve is to remove the two wires from the valve's electrical terminals and connect (from a known good source) its operating voltage to these terminal leads.

If the valve makes a clicking sound that tells you the piston is moving. You'll need to connect water to it to see if it allows water to pass through when the piston moves.

This test will both verify the electrical and mechanical operation of a solenoid valve.

If the valve fails either test, often disassembling the valve and thoroughly cleaning it will resolve the problem. There may also be o-rings, washers, springs, etc. which might need replacing.

UNIT STARTS TO KNOCK IN THE WATER MANIFOLD ABOUT 30 SECONDS AFTER BURNER TURNS ON. ANY IDEAS WHAT MAY BE GOING ON?


WAY TOO LOW WATER FLOW!!!
Check if your filter is clean, clean it any way.
Do you have a bypass valve installed and opened it too much allowing water to bypass heater?
Very possible now that your heat exchanger may have extremely restricted passage ways due to steaming/boiling calcium right out of the water and onto the internal wall of your heat exchanger or coil assembly.

Boiler Leaking Water - The Boiler Leak may not be the boiler


Went on one call today and had another query by Facebook about this so I though why not write an article about it. Both persons were very concerned as they saw water dripping from theirs boilers. A closer inspection for both showed that it had nothing to do with the boiler its self.

There are many things that can make water leak from your boiler. If you know for sure that the water is coming from a hole in the sections then you may have a serious problem. Usually though there is an easy fix for that also, more on that in another article. Both boilers today were leaking water from the relief valve.254c728.jpg

This valve is design to relieve the excess pressure from the boiler in case of a build up of extra pressure in the boiler. The extra pressure can come from a number of different things. A few of the causes may be a bad expansion tank, a bad fill valve or pressure reducing valve, or an open bypass valve. The bypass is easy, just close it and relieve the extra pressure. The others are not as easy.

Your expansion tank is simply a tank that allows water from the system to go in and out according to the pressure in the system.610ab3c.jpg This tank contains about ½ air which acts as a cushion to absorb the extra volume of water that is created as the water is heated. Hotter water takes up more space or volume, so it needs a place to go to when it is heated. If the expansion tank is totally full of water then, it will push water out of the relief valve. Changing your expansion tank will fix the problem.

If the reducing valve or fill valve is leaking by then you can also get extra pressure in the system.8e5ccb4.jpg A normal heating system will only run 10-20 psi pressure. Most well systems or city water is way higher than that. If the pressure in your boiler gets over 30 psi then it will begin to relieve the extra pressure by dripping water.

If you have a drip from your boiler this is what you check. First the expansion tank, the reducing valve, and the bypass valve that bypasses the fill valve. This valve is usually installed to quick fill the system, or purge the water lines of air.

Often there is just a small problem that looks like a big problem. Do not get excited and methodically check through the possibilities. You will usually find that the problem is not nearly as bad as you first thought that it was.

You need to bleed the air from the cooling system. The bleeder valve is located just behind the water pump housing. It is a small hex head (7MM) screwed into the coolant bypass tube. Pour coolant into radiator with the valve opened until coolant comes out of the valve. The cooling fans will not come on until the temperature reaches 225 degrees.

Hot water bypass


On the back side of the water heater you should see a water line connection at the bottom and one at the top. There should also be a water line connecting between the top and bottom lines. The bottom is cold water input and should have a valve. The top is hot water out put and may or may not have a valve, depends if there is a check valve installed. and the connection line between the two will have a valve. If you are wanting to bypass close the top and bottom valve and open the middle valve. If you are wanting to use the water heater, open the top and bottom and close the middle valve. Open the Hot Water on your kitchen sink and wait until you have a steady flow of water before you turn on the water heater.

No hot water flow through faucets


At the back of the water heater there will be a series of valves. One on the bottom, sometimes one on the top and then one in a line that connects the top to the bottom lines. Make sure the middle valve is closed and the top and bottom valves are open. If there is not a valve on the top that can be manually opened and closed then there is a check valve installed. This check valve will allow the hot water out of the tank but will prevent the back flow of cold water during the winterization bypass. If the valve on top is closed it will not allow hot water out. If the middle valve is opened it will allow the cold water to mix with hot water and defeat the purpose having a water heater. Close the middle open the top and bottom. If there is not one on top then the check valve is probably clogged or has failed and need to be cleaned or replaced.

My Teledyne Laars LLD spa heaters starts and heats for a couple of minutes thins shuts down. I have tried this several times with the same results. I hear the switch click and then the heater ignites and...


Since the heater fires it sounds like it could be the bypass valve stuck open. The bypass valve allows some of the water to enter the heater, while the rest bypasses the heater and returns to the pool.


If the bypass is stuck open, or broken, it allows the vast majority of the water to bypass the heater and continue to the pool. The water that is in the heat exchanger will become too hot due to slow flow and activate the high limit switch, turning the heater off.


The bypass is located where the pipes attach to the heater and can be checked or replaced if needed fairly easily.

1998 ford taurus, i dont have heat. my heater core is fine. yes i have tried to fix it.


This can be a bad thermostat that is stuck open or the heat bypass valve not opening. The bypass valve is located near the firewall and is controlled by the selector on the dash. the thermostat is of course located in the engine. If you check these and the are both ok,then the selector cable is broken or unhooked.

I have a raypak heater when i fire it up the water temp go's up real fast


I assume this is on a swimming pool. It might depend on how it is plumbed in. Quite often, there is a bypass valve allowing the pool water to bypass the heater incase it's being serviced, or a leak etc. You would close inlet and outlet valves to heater and open the bypass. This would isolate the heater. If you have the bypass open while heating, you will reduce (or eliminate) the flow through the heater. This will allow the water in the heater to heat very fast, and lets be glad there's a temp control or your plumbing would melt. These heaters should have full flow through the heater, and you'll see min temp rise per pass.
