Hello Bob,

In response to your answer to Peter’s question on web site: howtomendit.com, I would be very interested in replacement diaphragms for both the PH-10C and PH-5-3F water heater models, both of which are otherwise in excellent working order.

In the case of the PH-10C, with the pilot lit, there is a delayed response to the burners igniting when the hot water is opened, and then when it does ignite, it almost explodes!

In the case of the PH-5-3F, there is an intermittent small gas bypass to the burners, when the water is off, which clears itself when opening and closing the hot water, for a while.

Any assistance or information you can provide will be greatly appreciated. I am resident in South Africa.

With kind regards.
