Absolute plumbing Cape don't understand plumbing

On Friday the 30th May we had our solar geyser replaced after 12 years by Absolute Plumbing Cape after they quoted and I paid . On Tuesday the 3rd of June we contacted Absolute Plumbing with the following complaints : Solar panel not heating water Geyser heating very slow Water cooling down fast

Absolute plumbing came out the next day could not find the fault They came out again the next day still couldn't the fault. On Friday the 6th of June the owner of Absolute Plumbing came out and told me that there is nothing wrong with the installation and that it is working as it should and he has spoken to the supplier of the Solar panel and they say it is working as it should as well .

That next week I called Sunscan the supplier of the Solar panel and they told me that my complaints are valid and system is not functioning as it should. They gave me contact info another plumber.

New plumber came out on Thursday 12 June and identified the problem immediately with pictures and a explanation which I verified with Sunscan The cold water was connected in the wrong place bypassing the Solar panel.

I contacted Chris owner of Absolute plumbing with this information and he said that is not the problem and he will not change the pipes. He said he also spoke with another expert and my Solar panel is working like it should and that they have never had a problem not connecting the cold water that way even at his own house.

I then contacted my new plumber to change the pipes at my own expense.

When I informed Chris owner of Absolute plumbing of this he threatened me with cancelling my warranty and suddenly wanted to change the pipes that next week . Rain was forecast for that next week so I knew it would not happen and I had lost all confidence in Absolute Plumbing.

Alter new plumber changed the pipes my Solar panel and Geyser worked much better like knight and day . Solar panel now heats the water Geyser heats water much faster Water stays warm over night.

In my opinion Chris the owner of Absolute Plumbing Cape does not understand the basic fundamentals of plumbing and is dishonest
