Question about Grundfos Hardware & Accessories

1 Answer

We have a Grundfos Selector valve in the airing cupboard next to the water tank which is making a constant humming noise as well as a buzzing/static noise. We have switched the heating and water off but it still continues. Can you advise please?

Do you have more than one zone? If so, it is difficult to tell if the circulator in question is actually running. A trick is to get a screwdriver and place the metal end on the front of the circ and the other on your ear. You will hear it if it is running. If you do hear it, is the circulator itself very hot to the touch? If it is, it may be burnt out, or the zone needs to be bled of air. Another doubtful, but possible, answer is that the circulator is installed backwards. There is an arrow on it and it should be aimed towards the flow of water.

SOURCE: I have a Grundfos Comfort System. At the tap

Sounds like you have sediment built up in the pipes, and maybe the furthest faucet is the gathering place.
Take off each shut-off valve at furthest faucet and connect a water hose that flows into nearby toilet bowl.
You can buy garden-hose-to-1/2-pipe adapter at hardware.
Open water so it flushes the line into toilet bowl.
Then clean out valves and reassemble shut-offs and grundfos connection.
Remove faucet aerator and flush line up to faucet.
Install new aerator.

Grundfos JPF4A pump. takes a long time to get up to prime then once it kicks in after running water it gets to 50 shuts of but drop pressure instantaneously and kicks back in again. The constant on off...


The check valve is bad. When the system builds up pressure and shuts off the check valve prevents water from dropping back down the well line. When the check valve goes bad water drops back down the well line and siphons water back out of the well tank causing the switch to kick on and off constantly. The check valve will between on the well line coming from the drop pipe. It may be making a constant rattling noise as pump is running. Replace the check valve and you should be fine. Also check the pressure in bladder tank it should be 2psi below the "cut-in" pressure for the switch.

When u start it it just make a buzzing noise but doesnt fill with water


Hi, if there's no water at all, make these checks:
Is there water getting to the machine?
Is the water-volume selector switch set properly and are the control panel buttons pressed in all the way?
If you have a Maytag® washer, is the fuse (if there is one) in the control panel at the lid-switch bracket blown?
Is there a faint buzzing or humming noise coming from the water-inlet valve? (The water-inlet valve is the device on the washing machine that the fill hoses are attached to.) If you can't hear anything, the water-inlet valve may not be getting any power. If you can hear some noise and there's water present, you may need to completely replace the water-inlet valve.

Well-Rite WR240R makes loud noise every time water flows into it


Tank may be air bound. There is an air valve on top of tank. Take cap off and depress valve momentarily. If water comes out of valve, the bladder is torn, and new tank is needed. If no water comes out, check the pre -charge pressure of tank.
First, run water in house and take note of the on-off pressure of your pump. There should be a water pressure gauge on the water line going into the tank. Take note of the cut on pressure and cut off pressure. Most well systems typically operate at 20-40, 30-50 lbs of pressure. Next,shut off electric to pump. Drain all water from tank. Take a tire gauge and check air pressure of tank. The static or pre-charge pressure should be two lbs less than the cut-on pressure,i.e if your system operates at 30-50, then the pre-charge pressure should be at 28lbs. Adjust pressure as needed. A small air compressor is ideal to use if more pressure is needed.
