Decreased flow visable.

A pump that was installed 2 yrs ago has recently shown signs of decreased flow. All piping and pump function was checked and running, but when hooked back up to flex hose better but not full flow was visible. Do pumps lose strength after awhile? Or don't' they just die.

No they just stop, if your loosing flow it is from a block usually in the suction or quite often in the front of the pump the impeller will fill with stuff. A probe like a screwdriver and a set of needlenose pliers will fix this if you go in through the front of the pump.

Have a 93. bmw 525i turn over but won't start and put new fuel pump no spark no fuel recently was just running 2 days ago now won't start

Check for a bad fuse or fuse link built into the cable. check for battery voltage at the fuel relay. check the relay is engaging when the ignition is switched on and off . then check for voltage at the fuel pump by turning the ignition switch on and off, the computer will switch the voltage off if the engine does not start. check fuel pressure and flow, if flow is low replace fuel filter.

What is causing my polaris 180 to float more than its on the bottom of the pool?

The cleaner could be getting too much pressure from the return line, causing it to lose suction and fly off the bottom. Confirm that the blue restrictor disk is installed in the UWF to decrease water flow. If it is installed, try installing the red restrictor disk that came with your pool cleaner to decrease the flow even more. You should also check your wheel RPM. If it is higher than 32 RPM, unscrew the pressure relief valve to decrease the water flow to the cleaner. It is important to note that the pressure relief valve should only be adjusted when a restrictor is installed.

We installed a Grundfos MQ3-45B series pump in our house a year ago. It's been great except for a few occasions when it's been turning on frequently when no taps are on. First time it was a leak in the...

These pumps are activated by a flow valve on the incoming pipe. You should fine a small device, with a cable leading from it, attached to the incoming pipe on the pump. This device is a switch that is activated by the movement of a magnet that is held inside the pipe - the magnet is in a captive housing inside the pipe and is moved by the flow of water through the pipe. When a flow is detacted the magnet moves slightly within its housing and that activates the switch that is strapped onto the outside of the pipe.

So, either you are experiencing a flow that is unexpected or unknown (leaking outlet somewhere) or the intenal component of the flow switch is faulty, The latter can happen if some foreign material has got into your system and is causing the magnet not to fully return to the 'off' position.

You can disconnect the pump and remove the flow switch component to inspect and clean it. That process should be fairly intuitive.

If I can be of any further help please respond with a comment.

My saniflo has started to go slow- it now does small pumps - one every 30 seconds so takes 5 minutes to drain the bowl. I'm pretty sure no foreign objects have gone into it as it's only me and my wife...

Typically when solids don't leave the toilet after one flush or if it short cycles like is doing, then is definitely a pressure problem. Is the unit vented via an 1 1/2" vent pipe to the open air? Please disconnect the vent pipe and leave the vent connection open to the room, flush the toilet and check if it makes a difference. Air must flow in and out of the vent pipe at all times so it can work properly. An obstruction on the vent pipe can cause this issue. Also could be calcium build up inside the rim of the bowl. Pour a few cups of vinegar on the toilet tank and then flush the toilet, it should get rid of calcium right away.

Polaris 380 stand on nose while on will not move to wheels on ground what could be the problem

First, check to confirm that the blue restrictor disk is installed in the UWF to decrease water flow. It sounds like you are getting too much water pressure. You could also install the red restrictor disk to decrease water flow even more. If this does not work, verify the back-up valve is cycling. Hold the valve out of the water and watch the jet. It should come on and go off. Make sure that your thrust jets are working properly and are positioned correctly. Also, try removing the head float and shaking it. If there is water in the float, you will want to get a new one. Finally, check the hose floats to make sure they are
spaced evenly. One of these soultions should make your pool cleaner function properly. If you need additional help, please let me know.

My water is cooling in long copper runs and flow issues w/tkless

OK Lag the Pipes, you can get insulation that comes in two halves that goes around the pipes and uses "Ties" to hold the sides together. Or you could lag it with Hessian wrap, Anything you can wrap around and "Lag" the pipes with will be better than nothing.

How to set up my onga pump and filter its about 8 years old but looks like the currant model.just got it and they didnt have instructions bugger.

We begin at the suction line. I'll assume that you will be using this as a
pool pump since you have a filter. At the suction line, install a horizontal
or a vertical check valve along the suction pipe. Then the suction pipe
is connected to the bottom pipe adapter of the filter. The top pipe adapter of the filter shall be connected to the pump suction adapter. At the pump discharge adapter, install a GI Pipe Tee. At the bottom of the GI pipe tee, put a GI nipple going to the pump discharge adapter. Opposite it shall be the pipe plug to serve as the priming port. At the GI pipe cross, install a GI nipple about 6-inch long with a service **** to balance water flow. At the end of the service **** install another 6-inch GI nipple to attach a gate valve to control water flow. After the gate valve
is the discharge pipelines going back to the pool.

Note: Pump must be installed within 3 to 5 meters near the water source. You may install more than 5 meters but suction could be difficult for the pump.

Priming the pump:

Open the plug at the tee that serves as the priming port, Fill this up with
water to full level with the service **** at full close position. Once filled
up, replace and close the priming port. Put the power on, and start the
pump running, then slowly open the service **** or flow control valve
to appropriate level.

Just send your e-mail for further assistance. Thanks.

380 unit floats to the top, doesn't move around pool

Check the following three things. One of these should correct the problem you are having with your automatic pool cleaner.

1. Confirm that the blue
restrictor disk is installed in
the UWF to decrease water
flow. Or, install the red
restrictor disk to decrease
water flow even more.

2. Check the wheel RPM. If
more than 32 RPM, unscrew
the pressure relief valve to
decrease water flow
to cleaner. Note: The
pressure relief valve should
only be adjusted when a
restrictor is installed.

3. Verify the back-up valve is
cycling. Hold the valve out of
the water and watch the jet.
It should come on and go off.
