Remodeled upstairs master bath with Leland 3578 MPU DST lavatory faucet and 17278 Shower fixtures. Originally specified and installed 3/4" hot and cold water pipes to this upstairs master bath to avoid loss of water pressure and volume, especially to the shower. We have had wonderful shower pressure and flow for many years until we installed your lavatory and shower fixtures listed above. Is there anything we can to bring back our shower water pressure and flow? Regards, Unhappy Customer Frank Christianson
Hi Frank, We are sorry that you are experiencing a problem with your faucet. The model 3578-MPU-DST has a flow rate of 1.5 gallons per minute, most older faucets had a flow rate of 2.2 gpm which may account for the difference that you are seeing.
During the first few days you use your faucets, a small amount of debris may be flushed out of your pipe system. This happens even though the plumber flushes the pipes before completing work on your home. In addition, particles of solder, copper chips, Plumber's tape and other installation materials can get caught in aerators and shower heads. Occasionally, a chip might damage the valve seat that provides the watertight seal. The tips below will help you avoid problems. These procedures are a good idea to follow each time the water has been turned off for repairs in your home.
TO FLUSH A KITCHEN OR LAVATORY FAUCET:
Remove aerator and black sealing gasket above it
Turn faucet handle(s) to full on hot and cold mixed position(s) and flush lines for two minutes before turning off water with handle(s)
TO FLUSH A TUB / SHOWER FAUCET:
Remove shower head if applicable
Turn handle(s) to full on hot and cold mixed position(s)
Flush spout two minutes without moving handle(s)
If you have a shower head, divert water to it and flush for two minutes. BE SAFE! Make sure cold water flows FIRST and that the rotational handle limit stop is properly set. See information on setting the adjustable limit stop. Also, watch this how to video for instructions on setting the adjustable limit stop.
Replace shower head
Some debris and/or foreign material in the lines may be too large to pass through the faucet whether it is a kitchen, lavatory or tub/shower faucet. To remove this type of debris:
Turn off water supply to both hot and cold.
Remove all internal components.
Turn water supplies back on and let run for 30-60 seconds. (For kitchen and lavatory faucets turn a bucket or similar large container upside down over faucet to deflect the water into the sink.)
Turn water supplies off again.
Turn water supplies back on.
