Excellent service and advice from Fennel's Gas and Appliances

I have had a gas geyser for my house now for quite a while. On a previous occasion when it rained a lot, the geyser would not start, nor warm up the water. Because Fennell’s Gas and Appliances installed the geyser, I asked them to have a look at the geyser. Techs came out and opened up, cleaned out and in general gave the geyser an overall and service. Now recently with the rain that fell in Port Elizabeth the same happened, the geyser would not warm the water efficiently, no matter how high I turned the setting to open the valve. Normally with the valve completely open you cannot shower without opening the cold tap. However, now the water was not even close to warm enough for a comfortable shower. Again I requested the assistance of Fennell’s. Derek, the owner, made arrangements for a tech to come out to my premises. The tech arrived early morning and did full inspection of the geyser, found a diaphragm to be damaged and wet, and a metal part rusted, and this he replaced. (I am no expert, I am merely relaying what he showed and told me.) His next step was to check the regulator. After removing the regulator he indicated to me that when blowing on the regulator, same direction the gas would follow to the geyser, water was bubbling out. Because the gas cylinder is outside and mostly in the open, he indicated that water enters the regulator through a plastic cover, which obviously causes the water to be forced into the geyser with the gas, when a warm water tap is opened. This then in turn cause the flame to be either weaker or non-existent. His advice was to cover the top of the gas cylinder so that no water can reach the regulator. I have done this, and this morning between 02:00 and 06:30 we had 40mm of rain. We had a shower and the water was a hot as expected. So if you have a gas geyser and the gas cylinder is outside, make sure you keep the regulator dry. I would like to thank Fennell's Gas for excellent service and in particular Louis, who pointed this out to me. I think he did an excellent job and needs to be rewarded for his friendly and professional service. Thank you Derek and Louis.
