Can I adjustment my hot and cold shower set to increse the flow of the water?

All manufacturers must adhere to these standards and no adjustments can be made. In some cases, you may be receiving less than the maximum allowable water flow rate of the bathroom shower mixer set. Normally, this is due to low water pressure, a blockage in the plumbing or in the faucet, or a faucet malfunction.
