19 Jan 10 Troubleshooting an Electric Water Heater
I've read a lot to say do it yourself water heater tutorials and many of them from the top search pages the same. But I did not see an easy to understand tutorial does not work on the control of water heating elements, and why the water heater. While these do it yourself, what some tutorials to explain how the item that most of them say anything about the control of the thermostat and let them check valuable information.
So I will explain how "I"Go to troubleshoot water heaters and the thermostat. The first thing you need to do is to check to see if your power goes into the water heater, you can have something to do with a voltmeter, a few meters, you need the volt meter to the wires when the counter They have discussed a hot, there's constant power, when it beeps once, then not. If you're doing great. If you are not, then there is a problem in the breaker, it could have tripped, reset the switchusually solve this problem.
Now, the examination of the water heater can receive elements and the thermostat, you will need a voltmeter that has a resistance or ohms setting up. Before you start the panels and play with the power to secure the wires. I repeat: Secure the power of the kettle!. Next step is, take the two access panels, so you can equipped the thermostat and the heating element. Before you test the elements of a view of the thermostat settingto see whether the reset button is triggered. If it's the little red button is appeared to be just push it back in and the problem should be solved, if it does not let us on the examination of the elements.
Keep your meter to confirm Now the lines again, that the device is switched off! Use a screwdriver to loosen the screws or bolts into one of the cables on the item, it does not matter which wire loose touch it simply does not have anything on the item. Now select your voltmeter to ohms,if the voltmeter is OHMS 1 sentence should read it. A set screw and keep it there, the spacecraft to the other screw, when showing the 1-meter. (open), then good, if there were something like .003, 006 or "0 provides:" (closed), they eventually read 0, it is a bad elements and must be replaced. Then you will do the same to the other element.
The procedure is the same with the water heater thermostat, but it has more ports and wires then the element is not. Remove a wire from theThermostat, again it does not matter which. Keep a probe of the ad in the first screw, then use the second probe each screw on the thermostat to check read all OHM-1 on the test. Thats it, very, very simple. If you notice, in fact, that you are a bad element or thermostat then you have to replace. For information on visiting my blog thats listed below.
I hope this article cleared on things, whether you need a new heating system or waternot. And imagine that the only time you need to replace an electric water heater, if it so old that the outside of the leaking, as the lower part. If the leak from the top you could change the supply lines or nipples, in most cases, but really makes people, the elements and the thermostat of the water heater.

19 Nov 09 Troubleshooting a Hayward Sand Filter For Pools
My sand filter is running at high pressures
Follow the backwashing instructions in your Owner's Manual. The sand bed may be clogged with mineral deposits, that will not backwash away. Some calcium-based chlorine and other alternative disinfectant is in your sand bed and will require more frequent backwashing and changing of the sand.
Before you replace all the sand in a filter, you try to replace about 1 "from the top layer of sand, with theexact amount of sand you removed. Normal life of the sand is about 4 to 5 years.
You may need to clean your filter system with a special filter, please call Blue Haven Pools & Spas for more information.
Check whether it opens a closed or partially closed valve along your return piping, the valve.
Your pump is too small to provide sufficient flow for proper backwashing. Your filter will function, but a lower design flow rate will cause your systemBackwash improperly. Check the performance of the pump to be sure that your filter design flow equal rate. Replace the pump if it is too small.
My sand filter is running in short cycles
Improper backwashing could be the reason. Always backwash, the water remains clear and in sight of the valve, glass, usually about two minutes.
You may have live algae causing the filter clogging. By testing the water balance with a test kit and super chlorinating, you should resolve thisProblem.
There is sand at the bottom of the pool
The sand may be of use to be small, which pass through the filter system, then back into the pool. Remove the sand and replace it with the right quality of the sand – # 20 Silica or 45-55mm pool sand.
Your pump is too large for the filter. During backwashing the pressure can cause the sand to rise high enough to overflow into the standpipe, allowing sand to flow back into the pool. Talk to your Owner's Manual forthe right amount of sand for your filter.
It could be a loose lateral located at the bottom of the filter. Pull all the loose side, be replaced if defective.
Most calcium based chlorine, both powder or tablets contain 30 to 35% of what they are inert materials. This is calcium residue or dust, which many pool owners mistake sand. You can confirm this as follows: During vacuuming, use a hand VAC and Pol. Since VAC is approaching head, the sand was on thebe picked up below, and will allow himself. Most calcium residue will try to scatter of the VAC head when you pick it.
If you have this problem, we recommend that you put extra water in your pool and vacuum the waste line. If you vacuum to the filter, some of them on the sand surface are enclosed so that dust getting back into the pool.
The pool is not clear
Your pool chemistry may be out of balance, allowing algae to multiply.
The flow ratethrough the filter may be too low by clogged pipes or undersized. Cleaning the lines or changing to larger pipes will correct this problem.
Your filter operation time may not compensate for long enough for heavy use or hot weather. Try your filter for 24 hours until the water runs clear, then adjust to less running time.
Your pump can be connected to the wrong port on the multiport valve. If not properly installed, the filter will flow in the opposite direction. Make sure the pumpconnected to the port to "pump" on the valve.
You could backwashing too often. Backwash only when the pressure increases from 7 to 10 bar pressure on the start line, or if the return back into the pool is low.
My filter is loud
An oversized pump may cause noise in your filter valve due to excessive flow. To test, hold your hand partially before any returns to the pool wall. If the fault disappears, will confirm that the problem is excessive flow. Itcan be achieved by installing smaller eyeball fittings in the return (s fixed), changing the size of impeller in the pump, or switch to a 2-inch control valve.
My Vari-Flo valve leaks waste
The valve seat seal in the valve has become worn or loose. How do you replace the gasket? You need a new gasket and some Krazy Glue, and a sharp 1/8-inch wide flat screwdriver.
Note: Mark the top and bottom of the valve with a pen. It is very important that youdo not change the position of the cover when re-assembling. The cover, usually six screws removed. Using the screwdriver, scrape every last part of the seal and cement, to return to a clean, flat surface. Put a fair amount of crazy glue on the flat side of the seal. Place the gasket, flat side down, back to his place to dry – leave for one hour minimum.
