Pressure Systems:
The well pump draws the water from the well near your home; the pressure tank stores the water and regulates your home's water pressure. When you shower, wash the dishes, or run the washing machine, that water comes from the pressure tank.
Water pressure is measured in psi, or pounds per square inch, and represents the force at which water enters your home from the water main. Normal psi for a home pipe system is between 30 and 80 psi. While you don't want the psi to be too low, it violates code to be above 80.
Anyone who has a well for their household water supply should be familiar with how they work so they can effectively trouble shoot.
There are three types of pressure tanks: Air-Over-Water, Diaphragm, and Bladder, each with their own pros and cons.
Air-Over-Water Tank
These tanks use a single tank to hold the water and air charge. They usually have an internal coating to prevent corrosion. The terms “glass lined” or “epoxy coated” refers to the material used to line the tank and prevent corrosion.
The air and water are in a single tank with no separation. They’re not as popular as they were but are still used. The pressurized air pushes down on the water to create the pressure needed to supply your home. While they tend to be larger than other types of tanks, their capacity is similar to smaller tanks. This could cause the pump to cycle on and off more frequently and lead to premature pump wear and failure. They can be prone to getting water-logged due to the air loss trough pinhole becoming corroded.
Diaphragm Pressure Tanks
Diaphragm pressure tanks have two chambers: one for air, and one for water. They’re separated by a rubber diaphragm that’s permanently bonded to the inside of the tank, which rises and falls with the water level.
As water is pumped into the lower section, the diaphragm pushes up into the air chamber which triggers a switch that shuts off the pump.
While this is an efficient system, it does have its drawbacks. One is having the diaphragm come loose from the inside of the tank and letting water flow into the upper chamber. If this happens, you’ll need to replace the tank. The other problem is having the diaphragm fold over itself and causing a false reading which can lead to premature pump burn-out and the tank being ruined.
Bladder Pressure Tanks
The third kind of well pressure tank is the Bladder Pressure Tank. These use two separate chambers for air and water. The bladder is basically a large balloon filled with air that expands and contracts, triggering the pump. Since they’re self-contained, they don’t have the issues of a diaphragm or a single chamber tank. Another advantage is that since the water and air are kept separate, air is not absorbed into the water and therefore, there’s no need to have air added. Air bladders also tend to last longer than diaphragms.
They can have problems with water pressure or with short water pump cycles, which are usually because of a problem with the pump controls, with well or pipe leaks, and somewhat less often, a failure of the internal bladder, which may be replaceable. Another problem is having the bladder “get stuck to itself” and remain uninflated. This can cause rapid pump cycling.
Cost of replacing a pressure system is about $3,000. Your property inspector can tell you what type of pressure system is installed at your lake property.
Filtration Systems:
Treating well water is an effective way to manage issues that may arise from this untreated source of water. Each well depending on the area may have different water characteristics.The most effective way to find out the characteristic's of your water is to get a Chemical and Trace Metals Test completed.
Here are some of the filtration systems you may find in your Lake Property:
Sand Filter: Sand and sediment in well water is often a serious problem for many people using well water and will cause rapid deterioration of fixtures as well as appliances. Sand and sediment may cause piping to plug up with sludge and result in loss of pressure in your home. Fixtures, as well as taps, can become worn out, and home appliances including washing machines wear out ahead of their time.
Sand filters are normally installed in your water line before your pressure system. Depending on the complexity of the filtration you either need to replace the filter ($75.00) on a regular basis or the system might have a flushing mechanism.
Iron Filter: A couple of ways you'd know if you need an iron filter or not are orange/rust-like staining in your toilets, washing machine and dishwasher. Another is the metallic taste iron has when you're drinking it.
This media is designed to last up to 8-10 years depending on water chemistry and usage. The entire system does not need to be replaced, just the filter media.
This system is complex and will require continual maintenance and upkeep.
Water Softener: A water softener system for well water is an effective solution that improves the quality of your drinking water and extends the life of plumbing fixtures and appliances. Water softeners work by removing minerals from hard water, such as calcium, magnesium, and other dissolved solids.
A water softener should last 10 to 15 years. If your unit is facing more wear and tear, it could be due to improper maintenance or particularly hard water. If you'd like to extend the lifespan of your water softener, one option is to add a pre-filter.
This system requires monitoring and adding of salt on a regular basis.
Reverse Osmosis: Many Lake Property residents purchase bottled water for drinking and cooking. Over time this can be a big expense. Reverse Osmosis is a type of multi-stage water filtration method. It can reduce up to 99% of the contaminants in water. Reverse osmosis, or RO, is a water treatment process that forces water through a semi-permeable membrane to remove contaminants and other unwanted substances.
Reverse Osmosis (RO) Systems vary in capacity. Most home owners put a system in for drinking water and cooking.
These systems are usually installed under the kitchen sink and have a small tap installed on the counter.
Ongoing maintenance requires you to replace filters on a regular basis. Cost is related to the type and style of filter you purchase. Cost is approximately $100 per year.
Whole Home Filtration Systems: These systems work on the principle of ion exchange, replacing calcium and magnesium ions in the water with sodium ions, effectively softening the water. On average, the installation cost for a salt-based water softener in Canada ranges from $1,000 to $3,000, factoring in professional installation.
Choosing Home Water Filters & Other Water Treatment Systems
- What does the filter remove? Read the label to see if it is NSF-certified. ...
- How much does the system cost? ...
- How much filtered water do you need? ...
- What kind of system do you need, and how does it fit into your home?
The best way to determine if this is something you should consider is to consult with a professional.
