WARRANTY

Your new Shower/Bath Valve is designed for years 
of trouble-free performance. Keep it looking new by 
cleaning it periodically with a soft cloth. The use of 
harsh chemicals and abrasives on any of the 
Speakman custom finish products may damage the 
finish and void the product warranty. Please be sure 
to only use approved cleaners. Please contact 
Speakman for any clarification of acceptable 
cleaners.

This type of valve must be cleaned and maintained 
on a regular basis. Periodic maintenance should be 
performed at least every 12 months or after any 
changes have been made to the building’s plumbing 
system. Valves that are installed outdoors should be 
winterized by removing all of the internal parts and 
removing any standing water from the valve. 
Quarterly the maximum hot temperature setting (TLS) 
should be checked and adjusted accordingly. 

MAINTENANCE

Cover your drain to prevent loss of parts. Be sure to 
wear eye protection while cutting pipe.
