Move the slide switch to ON.
Open following link for recirculation system resources.
http://waterheatertimer.org/Water-heater-recirculation-system.html

The recirculation can work on either the timer or the thermostat using slide switch located next to the timer dial.
First of all, look to see if dial is rotating as time passes.
Next look at position of slide switch. If switch is moved to 'timer,' then the timer controls the on-off function for pump.
Move the pins located on timer dial to control on-off times.
If the switch is moved to ON, then the thermostat controls the pump, and turns on until temperature in pipe reaches 94 or 100 degrees F approximately. I forget exact cutoff temp.

I have a power star ae115 electric tankless water heater. It has performed flawlessly for approximately 5 years. A couple weeks ago it stopped producing HOT water but is still heating to Luke warm. The "...


5 years is about the lifespan for tankless.
You might have shorted element. That would explain cooler water and tripping reset.
Test element: power is off, disconnect wires from element; ohms = voltage squared divided by watt rating of element

Pool pump breaker tripping


1) Not likely the timer is problem, unless there was fire or overheating in timer box. Use nose and eyes to inspect for signs of high heat.

2) Eliminate timer as suspect:
Move wires on timer to test if timer relays have gone bad.
Move terminal 4 to terminal 3
Move terminal 2 to terminal 1
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T104

3) Check watt rating of Hayward pump, and voltage.
1Hp motor at 240Volt draws 8 amp, and can draw 6 to 8 times that amount when starting. Up to 100 feet, should be at least 12 gauge wire and double-pole 20 amp breaker. Over 100 feet, 10 gauge wire and 30 amp double-pole breaker is best.
http://waterheatertimer.org/Color-codewire.html#motor

4) Intermatic T104 240V timer is rated 40 amps
Can safely handle 1 Hp motor without nearing heat-rating capacity of timer

5) Make sure the motor is wired correctly for 240Volts.
If motor is wired for 120, and 240 is applied, then tripped breaker can result.

My Paloma 42PVN shuts down and shows code IL. The manual says it's Lime deposits. How do I remove these deposits. The unit has been running fine for over 1 year but now it only runs intermittently and...


You need a 5 gallon bucket and a small sump pump that connects to a garden hose. The hose connects to the inlet of the water heater and and then run a second hose from the hot water outlet into the bucket. Pour in about a gallon of white distilled vinegar. Turn the pump on and let the vinegar run through the heater for 15 minutes. Reverse the hoses and run another 15 minutes. reconnect the heater and test the water flow. You may need to repeat these steps several times to remove enough debris and buildup.
Installing a water softener treatment system will prevent the buildup from occurring so fast, if ever again.

There seems to be a flow problem. The pressure starts out fine and ends up a trickle but only on the hot side. I have used the T & P valve to try and back flush the unit , to no avail


In order to clean the unit you need to connect a small sump pump to the cold inlet, and run a hose from the hot side into the same bucket. Pour about a gallon a white distilled vinegar in the bucket, and turn the pump on. Let the solution run through the unit for about 15 minutes, then reverse the hose connections and run the pump for another 15 minutes. Reconnect the water supply and outlet. Turn the water on in the bathtub first on the hot side and let ir run for a few minutes before turning the power back on to the heater. While the water is still running turn the power back on and reset the thermostat. If you get a lot of debris in the bucket, you may need to consider installing a water-softener to prevent scaling.

Slow leak from what appears to be some kind of adjustment screw on top of pump , solution to stop leak


This is probably just the plug that is used to prime the pump if it looses it's prime, but I can't be positive since your description is a bit vague. I suppose that if you thought it adjusted something that you would be reluctant to just tighten it. Go ahead and tighten it. If it still leaks, then do the following:
Get some teflon tape (ask for it in the plumbing section at home improvement store or hardware store - $2 or less) Get a helper (a child will do). Turn off the power to the pump. Turn on the water at the kitchen sink until it stops running, then turn it off again. Now remove the leaking screw. Some water will come rushing out, but have your helper push his/her thumb over the hole (don't put a small finger IN the hole). Wrap the teflon tape around the screw in a clockwise direction as viewed from the bottom of the screw. Wrap about 5 layers, nice and snug. Don't leave a loose end that will dangle from the bottom of the screw. Put the screw back in the hole, nice and tight. Good luck, Al K

Can I reduce hose size from 1- 1/4 to a 5/8 garden


Hi,
The short answer is no.
You will not get any flow and wreck the pump.
Go to a Home Depot, Lowe's or Plumbing Supply House and get a 100' roll of black Poly Pipe and roll that out over the ground. The check also has to be at the end of the pipe and the pipe shoud slop away from the pump if possible. This will make it much easier to prime the pump. Air will cause the pump to lose it's prime so you want to get all of th air possible out of the pipe before starting the pump.

I hope that this will help you to solve your problem!

Thanks for using Fixya!!

Running out of hot water after 5 minutes or so in the shower.


I think the dip tube in your water heater has failed, this is a plastic tube that goes in the cold side of your tank and forces incoming cold water to the bottom of the tank allowing hot water out at the top. When this tube deteiorates the incoming cold water mixes at the top of the tank causing the problem you have. the dip tube runs about 5 bucks but takes someone with pluming skills to install.

Parkray Cumbria efficiency problem


Some circulation pumps have a 3 phase mixing valve (cold,warm,hot) to regulate the water pressure in the building; no way to know unless you trace the plumbing. Basically, the hot water temperature could be lost because the circ-pump is cooling it with the cold water supplied to it. This is used to balance the pressure (aka Pressure Balancing Circ-Pump), so heater is really working overtime to heat the water. If the pump has two in and one out that's more than likely your problem; but you should consult a "old-school" plumber in your area.
