Question about Laing Thermotech Autocirc Undersink Instant Hot Water Circulating System

1 Answer

For some reason, after 5 years, a small leak has developed where the hot water exits the autocirc2 tank when you turn the hot water on. I removed the fixture where the plastic tubing hooks on and the only reason I could see why it might even remotely be leaking is because a couple of the threads are stripped..though it is hard to believe that is the issue. Can I order another of those small plastic valves of you don't have an answer?

It's true, nobody has 100% perfect answer for broken stuff.
Open following link for some autocirc resources:
http://waterheatertimer.org/Water-heater-recirculation-system.html

If I understand correctly, you removed supply line that connects autocirc pump to the hot water shut off valve.
Buy standard sink supply line at local box store or plumbing supply.
If memory serves, the supply line is 1/2" IP thread that connects to pump and 3/8" Compression fitting that connects to shut off.
You might try using thick-bodied white teflon joint compound to help seal the connection.
I use rectoseal on threaded connections and tubular drain connections to ensure forever seal:

If brass part of pump is cracked, then autocir may be bad.
I have no idea how to permanently fix a broken brass water fitting, and would suggest replacement at that point.

How to clear Major plumbing clogs


I am assuming that you are referring to a calcium or rust build up in the water heater.
If you are having this issue you will need to turn off the water to the heater. You will need a garden hose, access to a outside water soucre, cold water is fine.
Shut off the gas or power to the hot water heater before starting.
Now you will need to place the garden house on the drain fitting on the water heater, placing the end of the hose outside and lower than the drain valve. Open the valve and drain the heater, you will need to open a hot water faucet to help drain the heater. I don't suggest opening the TPR ( Temp Pressures relief )valve due to the fact that they sometimes leak or don't reseal after opening them.
Hopefully the drain valve is not clogged, you should hear and see water exiting the garden hose.
If you are not getting any water from the drain valve you are going to have a challenging task.
If no water is coming out, my recommendation is to get the required tools to remove the hot water line from the top or side or the heater, also a few towels to soak up water A bucket is helpfull also.
remove the hot water line, then you will have to use a small hose to siphon the water from the tank. Once the tank is empty you can then remove the drain valve and replace it.
once you have replaced the drain valve you should ensure that it's closed and use a Gallon of CLR. Poor this into the water heater through the hot water outlet where you removed the pipe from. Now make sure the faucets are closed and replace the hot water line. You can now turn the water back on to the water heater.
After a few minutes open a hot water faucet to let out any air until water flows out, than close the faucet.
Let the water heater set for a few hours, then drain the tank!
when the tank drains, close the drain valve again and refill the water heater. Once again open a a hot water faucet and let the air out till the water heater fills. Again let sit for a hour.
At this point open a hot water faucet at the farthest point from the heater and let the water run for 5 min. , than close it and move to the next closest faucet and repeat until all faucets have been opened and run for 5 minutes.
If you still have a slow flow in a faucet, you may need to repeat the CLR step.
I also suggest that you remove all faucet screens and clean them.
If you still have a clog than you are going to have to remove or replace a piece of water line in the house. The blockage may be hard to find but if you have access to most of the pipe or it's visable you may be able to hear the blockage with the water on. Otherwise this will result in using some water line taps and a pressure guage to find the blockage.

I have a reliance 501 propane gas water heater how do i change a thermostate


Hi,

To change a gas hot water heater thermostat you will need to first buy a new gas valve for your hot water heater. The gas vaive and the thermostat are integrated into one unit.

To replace the thermostat on a gas hot water heater you must follow these procedures....

1. Turn off the incoming water and drain the water heater.

2. remove the pilot tube, the burner gas tube and the thermocouple from the gas valve. Turn off the gas line and remove from the gas valve.

3. get a pump pliers or a wrench in behind the gas valve and turn the whole assembly CCW to remove it from the tank.

4. After appliying pipe dope or tape to the new gas valve threads, turn the new gas valve into the tank by turning in a CW direction. Be careful not to damage the small wires to the ECO. They are the little red wires on the back. If you break them the assembly is irreparably damaged.

5. reinstall the gas line, thermocouple, burner tube, and the pilot tube to the gas valve.

6. Fill tank with water. Make sure to open a hot water faucet and purge all air from the tank.

7. Check for leaks where the gas line hooks up with soapy water.

8. Relight pilot light and check operation.

9. Set the new temperature setting to a medium setting and then adjust the temperature to your likeing from there and adequate time for heating completely.

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

I have a Rheem 40 gal. tank that is leaking water front the top where the vent stack is. It is pouring out. Can it be repaired?


A leaking water heater cannot be repaired, assuming it's the tank leaking and not nearby water pipe.
http://waterheatertimer.org/Water-heater-leaking.html

First thing is to protect your property from catastrophic tank failure where tank ruptures and water runs until it is shut off:
Tanks are under pressure when they are hot.
Close cold water shut-off located above tank.
Turn control knob to 'pilot' so pilot is lit but burner will not turn on.
Open hot side on tub for few moments to relieve tank pressure.

Now your property is safe.
You need a new water heater.
In mean time, gas water heater makes 41 gallons hot water per hour.
Shower used 5-9 gallons hot water.
Bath uses 10-15 gallons hot water.
You can turn on water heater for short stretches and limp by until you get a new heater.

Leeking water from bottom


I wrote a page on leaking water heaters with resources and information:
Page lists things to check.
http://waterheatertimer.org/Water-at-bottom-of-water-heater.html

Also run hand over tank to find warm spot that says where leak is coming from
A rusted tank cannot be repaired.

If your tank is rusted out, it might burst open and flood the area.
Hot water inside tank is under pressure.
Turn off heat source to water heater.
Turn off water valve located above tank.
Open tub faucet on hot side and relieve pressure from tank.

You can limp along with a leaking water heater by turning it on when hot water is needed.
For example a shower uses 5-9 gallons hot water.
Turn gas water heater on for 15-20 minutes.
Turn electric on for 20-30 minutes.

I have a Therm x Trol on my water system. It has a small leak in the top. I'm on public water in a subdivision. Do I really need this device? Can I remove it with out harming my home?


depends on why it was installed in the first place...

most of the time these are installed to reduce thermal expansion... "hot water into the cold pipes"

I don't know your system, but I would just replace it. removing it could potentially bring back, or cause other problems we are not aware of, the reason it was actually installed.

Only have about 15 min of hot water and the water is not as hot as it use to be


Water heaters will fill up with sediment,because of this they have a less than 10 year lifespan.As they fill with sediment you have less room for water and it's harder to heat up.Try and flush the heater by opening the over flow valve for a couple of minutes.Open the drain at the bottom too.
One thing,as with any build up,once cleaned you can develop a leak.The reason being that there had always been a leak it was only plugged up,and by cleaning you will sometimes find a leak that never was there before.That means the tank integrity is gone and will need replacement.
Nuff said?

Water does not stay hot for very long. Runs out


the problem is your 8.5 year old water heater.

Have you regularly drained out the sediment from the bottom?

Is it possible that the dip tube has corroded and fallen to the bottom?

8 years is a good life for a hot water heater ... it might be time to let it go ...replace it before it starts leaking and causes more trouble.

There could be other reasons for this difficulty ... still i think you have gotten your use from this unit.

Dont kill the messenger in this case.
