Treated water is dispensed in the laundry, faucets, kitchen, toilets, baths, showers, etc. and, water dispensers provide clean water throughout the house, when a whole house water filter is attached to the house’s water main line. The hot water heater is generally connected to the main water line after the whole house water filter.
The main water line is generally split into two branches generally known as the ‘yard’ and the ‘house’, in the foundation slab of the house or in the ground in front of the house. On that account, a problem is likely to be faced by those who aim at cleansing water for their garden and have had a sprinkler system installed. In this regard, assistance may be obtained from the blueprint of the house or the city’s water utility.
Hardness is caused in the water of private wells by contaminants like minerals, sediment and iron and other metals. On the other hand, hardness is caused in the water supplied by the municipality, by contaminants like minerals, sediment and chemicals. It is important to find out about the kind of contaminants present in water, in order to arrange for its proper cleansing. The various kinds of contaminants that the water may contain may determine the kind of whole house water filter required in a particular case.
To have the composition determined exactly, it is important to have the water tested. An analysis of the water can often be obtained from municipal water utilities, by submitting a request. One can have the test conducted by a laboratory in the local area, in the case of a private well. Since they usually have experience related to the contaminants found in water from the local wells, the county officials can also prove to be of assistance.
Before a whole house water filter is acquired, it is important that the following should be carefully examined:
- Rate of Flow: The dishwasher, shower, heater for hot water, toilet, etc, require water and the quantity that is available is termed as the flow rate. Gallons per minute (GPM) are the units for measurement, usually. The toilets and appliances have demand ratings in printed form and these can be used for requirement calculation. Dishwashers typically require 3gpm, whereas 5gpm is required for toilets and 2.5-5gpm is the requirement for showerheads. When maximum use is being made, pressure of water has to be comfortable and uninterrupted. For that, 10gpm is typically the minimum requirement and it may go up to 40gpm. So, a whole house water filter has to meet those standards.
- Size of the filter: The pressure is likely to be greater and more water likely to flow, when the service interval is longer and the filter is larger. Pressure and GPM are impacted greatly by the port size. A filter of 4.5″ x 10″ may be appropriate and pressure fall-offs are likely to be infrequent in the case of condos or small houses, especially when the sediment levels are low. The filter size that is ideal is 4.5″ x 20″ for most homes.
- Life of the filter: With a regular back wash cycle and backwashing valve, a longer period of trouble-free use of a stand-alone carbon filter with a carbon bed is likely. When water supply by the municipality is normal, 100,000-150,000 gallons of water can be cleansed, usually, by a 4.5″ x 20″ carbon filter cartridge. The quality and quantity of the sediment impacts the life of the sediment filter.
- Size of the port: The port size that is ideal for a whole house water filter is 1 inch. For a home that has a 5/4 inch piping, when a 1 inch ported system is used, not many problems are likely to occur. When a whole house water filter system with 1 inch ports and 4.5″ x 20″ filter is utilized, the pressure droppage is minimal.
