Rheem hot water unit

[Lionel]

G'day all, A Rheem series 101, 50 ltr unit. Two problems, when up to temp the overflow begins running. Is the relief valve servicable. [new one over $100]. Secondly, it is on a dedicated 16 amp curcuit has a 15 amp 3 pin plug. When it kicks in the lights in the house dim a little and conversely brighten when it shut off. Decided to replace it with a larger unit and not sure which way to go. Gas is not an option even here in WA [ $95 per bottle] What resource boom ? Electric storage or instantanious, seems to be a lot of models available. I would love some advice on this matter...Cheers........Lionel

No. And despite the message stamped on them of "test by releasing valve every 6 months" we recommend that you dont touch the valve, any impurities within the water that run through while its open can cause it to leak later on and reduce its life. They are best left alone and replaced when needed.

Along similar lines, while a thread on hot water services is underway, what can you tell us about the sacrificial anode? How often should these be replaced, if at all?

I have only recently heard about these things.

How often should these be replaced, if at all?The anode basically prevents corrosion of the tank. Depending on the quality of the water in your area its recommended to be replaced around the 5 year mark. If the anode corrodes completely and isnt replaced then your tank will start corroding and you will get leaks.
