Thermostat and Diaphragm Rebuild Kit (previously known as Waterside Maintenance Kit) for Myson 325 & Thermar TL200. A "tune-up kit " to resolve leaks at the thermostat and diaphram housing area and to resolve fluctuating hot water due to faulty diaphram and "O" ring seals. Kit Includes diaphragm, silicone lubricant, 9 assorted 'O' Rings for Thermostat Repair, plus complete instructions. 

A leaking thermostat will lead to rusted parts and improper heat modulation.  Let it go too long and you will need to purchase a rebuilt thermostat.  We recommend one of these kits about every five years.  If properly maintained, your thermostat should last for decades.
