  • Stay away from the Metal Parts: as you will notice with the time, the majority of valves with metal parts do not stay that long. They easily corrode. So when it comes to choosing the right valve, just go with the one with no or very few metallic parts. This will save you from having to run to the stores within a short period of use. As you know, corroding metal tends to be weak and would be leaking in no time if care is not taken.
  • Inlet holes that are low: some tanks are low fill meaning the inlet is very low to save water. This means that the fill valve will need to accommodate this feature if it is going to work efficiently. However, you will need to confirm that yours is a low flow toilet first before going for the low-hole valves. It is not all toilets that have low inlet.
  • Price: the price of any product must match the quality if it is to be considered adequate. Don’t run for the most expensive fill valve thinking that it is the best. The most expensive is not always the best quality. But don’t go for cheap products that will make you regret later. Look at the features rather than the price – the price can sometimes be very misleading.
