It only takes one action (i.e. pushing the lever) to trigger a series of actions (i.e. release the water, drain waste materials, refill the cistern). Given this, one malfunctioning component can render the entire system non-operational. On the bright side, it makes Saskatoon plumbing repair much more efficient.
If the bowl water refuses to go down, something is probably blocking the S-trap or outlet. If the flush lever is unresponsive, there might be a problem with the mechanism that opens the valve. A trusted Saskatoon plumber diagnoses problems according to the symptoms, such as those described, and comes up with solutions based on his years of training and experience.
