The faucet is rated at 6.7L/minute (<2 gal/m) and I would expect that's a design of the cartridge. You could measure flow with spray head attached, then remove head (see link) and measure again to see how much the head reduces rate of flow. You could try removing the check valve(s) but not sure if that will work as it may leak.

I would suggest that if the low flow is affecting the hot water only that the filter is restricted where the tap plumbing joins the house plumbing. The filter is in a small housing which is right next to the house plumbing. Turn off the hot water supply and ensure the mixer is in the off position. Disconnect the hose adjacent to the house plumbing using a 19mm and also a 10mm spanner to stop the thin hose twisting. Then use a 13mm spanner to unscrew the filter housing.

It's the water pressure going through a small opening. Possibly some debris in the inlet.

28487001 is not an electronic shower head made by Hansgrohe. It is an overhead shower head that has no electronic parts. Triton is a completely different company. If you have an electronic shower system by Triton you will need to contact Triton. If you have a Hansgrohe product feel free to contact Hansgrohe at 1-800-334-0455.

Most manufacturers of faucets and shower heads install flow restriction devices at the factory when building the products. These devices are proprietary in most cases and are made to be difficult to remove and in some cases removal will damge the product. There may be some after market flow restriction devices that are made to be installed between the shower arm and shower head but I am unaware of any specific models or brands. If you need help with any Hansgrohe products feel free to contact Technical services at 1-800-334-0455.

First thing to check is the filter screen at the hose connection on the hand shower. If this screen is clean and there is no debris in the flow restriction device inside the handle end you will most likely need to clean the hand shower spray face. You can remove the unit from the hose and soak the spray face in CLR. Follow the instructions on the container for use and dilution. Soak for no more than 10 minutes at a time. After soaking, rinse the unit well and reconnect to the water source. Run water through it and while running rub the rubber spray channels to further clear up any deposits. Repeat the soaking and cleaning process at least two more times to clear out all deposits that may be limiting your performance.

Is it a Grohe or Hansgrohe shower head? If it is a Hansgrohe shower head the first thing to check is if the self sealing filter gasket is installed at the connection to the shower arm. Hansgrohe shower heads have a black self sealing filter gasket in the head that some people remove assuming it is a flow restriction device. It is only a filter and does not restrict flow unless clogged with debris. Next make sure the flow restriction device below the filter gasket is still installed. On some models removing the flow restrictor will cause water to be expressed from the air injection ports near the pivot ball. Feel free to contact me at Hansgrohe. 1-800-334-0455.

Hi Christieb942,

When you get a new hand shower you can sometimes get sediment on the federally mandated FLOW RESTRICTOR. Not screaming, that is ****** in cheek. To CHECK the Flow Restrictor for debris, look at the hose connection end of the hand shower. You will see an INSERTED part that is green, yellow, or white. We have to push that in there to satisfy the EPA requirement for flow. You can pull it OUT and rinse it off. Then connect your handshower and try it and see if it is improved. You will not void the warranty in any way by doing this. I hope you understand what I am telling you, but if not you can call me 800-334-0455. I wish I could answer more directly, but Big Brother has eyes.

Check the 94282000 cartridge for debris on the filters. If your boiler requires a certain flow rate to come on, then you must get enough flow through the cartridge to make that happen. Also, if your boiler is producing very hot water, the cartridge will self regulate and reduce the hot flow accordingly. try lowering the output temperature of the boiler to resolve that possibility.

If you need further assistance, you can call us direct at 800-334-0455

You need to replace the part they are not serviceable
