WILL MY HYDROCHASSE MAKE A NOISE WHEN REFILLING?
According to our product testing, Hydrochasse tanks reach a volume of 55 dB during refilling
A > Does your Griffon make a “snoring” sound while refilling?
Tighten the grub screw to reduce the filling flow rate - this will prevent noise and vibrations during refilling.
MY HYDROCHASSE IS REFILLING TOO SLOWLY ?
The Griffon system was designed for optimal functioning with water pressure of 3 to 5 bars.
A > If your Griffon takes a long time to refill, it is because the water pressure on your installation is insufficient...
Loosen the grub screw, to increase the filling flow rate
B > If the problem persists it is because your installation has water pressure of less than 3 bars
For water pressure less than 3 bars, it is possible to pull out the grub screw completely in order to increase the water flow. Below 2 bars, a pressure booster must be installed for the system to function properly.
MY HYDROCHASSE IS SPLASHING WATER ?
Griffon recommends a selection of toilet bowls to channel the water flow inside the toilet.
A > If your installation seems to be trying to become a shower as well, this is because the water pressure is too high.
The flush mechanism is controlled by tightening or loosening the stop screw located on the flush lever:
1 - Remove the handle without shutting off the water (see procedure below) - It is not necessary to shut off the water
2 - Tighten the stop screw for a stronger flush action and loosen to reduce the force of the flush action;
3 - The stop screw may have become loose, or there may have been a change in water pressure. In this case, adjust the screw (see below). You could also fix the screw in place using a thread-locking fluid to ensure it does not work itself loose
MY HYDROCHASSE IS NOT REFILLING ?
Griffon, as with any sanitary appliance, does not like limescale...
A >The water has been shut off or limescale build-up is causing seepage.
Empty the tank then refill it again (see part 3)
If you find you need to do this on a regular basis, we advise you to place Teflon on the connector located between the isolation valve and the water inlet for the pipework, as well as between the pipe and the isolation valve.
If you live in a hard water area We recommend that you install a water softener
B > If the pipes are blocked
Shut off the water supply and remove the grub screw. Replace the cover screw and turn the water supply back on, check that the tank is filling up
If the problem persists despite this intervention:
C > The handle is too stiff
MY HYDROCHASSE IS LEAKING ?
The installation of a Griffon unit is straightforward but the steps set out in the instructions must be followed.
A > Your Griffon is leaking through the pipework : your water pressure may be too high.
For installations with water pressure exceeding 5 bars a pressure reducer must be installed for the system to function properly.
B > There is a leak between the pipework and the tank when I work the flush.
C > There is a continuous leak between the pipework and the tank.
D > There is a leak around the handle.
Check that the waste pipe is not installed too far inside the toilet bowl.
If the leak appears when the unit is installed, it may be that the flush action is too strong, in which case make any adjustments necessary (see part 2); E > If the leak appears with use.
F > Water is running continuously into the toilet bowl.
The ball float located in the cistern seals the cistern when the flush lever is not in use. It could be that it is not positioned correctly and is allowing a trickle of water to escape.
To put it back in the correct position :
If this does not solve the problem, it means the ball float is worn out and must be replaced
G > The flush lever is too loose.
Check that the water supply has not been shut off and is not blocked.
