Reverse Osmosis Drinking Systems & Water Softeners Needed Maintenance
An existing customer in Zurich passed our name along to his neighbour after we recently visited his house to do a water test and filter change. The neighbour had been having some problems with the water coming out of their drinking faucet too slow. The pressure was low and they had tried to change the filters themselves last year but ran into some difficulties with some of the fittings leaking. They decided to have us come out and take a look at the system.
The holding tank for the purified water was sitting on the basement floor and had to push the pure water 9′ vertical to get to the reverse osmosis faucet at the kitchen sink. We moved the tank so it was mounted just underneath the floor joists. Now it only has to push the water 3′ vertical. This small improvement, along with boosting the tank pressure, means they will be able to fill the coffee pot more quickly. Instead of a slow tickle, the purified water will shoot out in a steady stream.
In addition to testing the water at their house, they asked if we would head over to her Mom & Dad’s place just around the corner. Upon arrival, it was discovered that the water from their reverse osmosis system had an unacceptably high level of dissolved solids in it. As well, the water had over 15 grains of hardness in it. The water softener wasn’t working properly either.
The softener was an easy fix. The problem was that the salt had clumped together at the bottom of the brine tank and was blocking the slits where the brine water was drawn through. Whenever the softener would go through a regeneration cycle, it wouldn’t get enough salt. As such, not all of the calcium was removed from the resin beads and they would only have soft water for part of a day before it went hard again.
The reverse osmosis had a couple of issues. The first was that there were 2 sediment filters in the pre-filter sumps instead of 1 sediment and 1 carbon filter. Without a carbon filter to remove the chlorine from the town water supply, the membrane wasn’t being protected. As such, it quickly deteriorated and didn’t purify the water down to the microscopic level like it should have. As well, there was no flow restrictor on the drain line. The nice thing about these drinking systems is that they are self cleaning. Normally there is a slight trickle of water washing over the membrane to send the contaminants down the drain. In this case, without the restrictor, the drain water was running at full flow. We replaced the membrane and added the proper drain flow control and got the system working properly again. They now have perfectly soft water for the dishes, showers and laundry – and – purified filtered water for drinking and cooking.
Both families have been added to our service records for an annual visit and we will call them each year.
