In case of high pressure boiler phosphate content is monitored and is preferred to control caustic alkalinity. Phosphate treatment should be given directly to the boiler drum with a chemical pump as if introduced into the of the boiler through feed pump, most phosphates will react with the impurities of water and may cause deposits in pumps, piping, feed water valves etc.
If the leak is coming from the pressure valve it could be the case that the boiler pressure is too high. Meanwhile, a leak from the pump seal is a sign that it may have worn out and need replacing. In the case that the boiler is leaking around the pipes or tank then that's a strong indication of corrosion.
