The toilet flush is too weak

Toilets really have a lot to offer. Especially in households with several people, they are in use throughout the day. But even in 1-person households, the toilet is permanently high demands. Then one or the other damage or a fault may occur. A classic disorder is a too weak toilet flush - even if the cistern is always full of water. Below, we have set up possible causes and measures for you, even if your toilet flushing is too weak.

The different toilet types

Even if it does not seem so versatile, there are in this country but different toilet designs that are used:

  • Floor-standing WC
  • Wall or hanging toilet
  • Pre-wall installation (surface or flush, cistern in the pretext element)
  • Cistern placed on the toilet
  • Cistern hanging on the wall (normal and high hanging)
  • Flush valve toilets

Pressure washer with too weak toilet flush

Pressure washers are hardly used for toilets. Rather, they are used in urinal assembly. Usually there is a defect in the actuation mechanism or the purge valve is calcified. If the valve is calcified, you can proceed as with any other decalcification.

Differences in toilets with cistern

Much more often, however, it happens that the water pressure on a toilet with cistern is too weak. All other listed toilet systems are types with a cistern. The biggest differences can be found in the operation. The functional principle, however, is always the same. You can use the following tips and information for all WCs with water cistern.

Water cisterns in the wall installation

Only in toilets with flush-mounted wall installation, the cistern is a bit tricky to achieve. To do this, remove the pusher plate. Behind a module frame is screwed on. In turn, there is the actuator module for water flushing. When you remove the module, the opening takes on the task of a revision flap. Otherwise, the cistern construction is always very similar.

Differences in the flushing technology in the toilet bowl

In the toilet bowl, however, you must also distinguish different versions:

  • Toilets without flushing rim
  • washdown
  • washout
  • single rinse inlet or several "nozzles" or inlet openings

In particular, if the toilet flush is too weak, this is due to deposits such as lime or other dirt particles (sand). You can first decalcify the cistern, but in many cases there is a massive deposit in the flushing holes and channels of the toilet bowl.

The high risk of deposits in the flushing channels of the toilet bowl

In addition to calcium deposits, it can also come here to Urinsteinablagerungen. Urine stone remove like lime. Preferably, you should use acids such as those listed under "Toilet descaling", including the mixing ratios.

The descaling of the rinse feeds in the basin ceramic

If you explicitly want to descale the inlet area to the flushing openings in the toilet bowl, it is recommended to completely empty the cistern. Then allow a small amount of water to run in and add citric acid. Compared with other acids, this is not liquid, but powdery.

The acid must be able to work in the flushing channels

Run as much water into the cistern that it is enough to carry the citric acid into the flushing channels of the toilet bowl. Then you should leave the acid at least overnight. For the rest of the descaling, proceed as we described in the linked guidebooks.

Tips & Tricks

Particularly with hard water, calcification is not the only reason for the high lime content that is given. The lime also reacts chemically to urine. This then leads to the formation of urine stone. Of course, it can form everywhere in the toilet bowl, where urine also comes. For very hard water, therefore, the conversion to a rainwater flushing is recommended. Rainwater is neutral. Thus, it contains no lime, there can be neither lime nor urine deposits.
