4 FM quick reads on plumbing
1. Plumbing Systems: Setting Retrofit Goals
I'm Dan Hounsell, editor of Maintenance Solutions magazine. Today's topic is, setting plumbing upgrade goals.
When maintenance and engineering managers make the decision to upgrade restrooms in institutional and commercial facilities, they typically are motivated by one or more common goals.
They might want to reduce water use in restrooms in an effort to curtail utility costs. They might want to implement a design that reduces maintenance costs by making it easier to keep the restrooms clean. In some cases, user complaints might motivate them to seek a new restroom with improved hygiene. Or they simply might want to bring the image of the restroom projects in line with the rest of the facility.
How well managers achieve their desired goals depends on the care with which they approach the process of planning upgrades. Managers should start the restroom upgrade process by clearly identifying the goals of the project. Forget cookie-cutter approaches. Most likely, they are the cause of the restroom's current problems. Instead, managers should approach every decision with a clear understanding of the way it will affect the desired goals of the upgrade.
For example, if one of the primary goals is to reduce cleaning costs, managers will need to evaluate the impact of every element in the new restroom design — including ceilings, floors, fixtures, surfaces and finishes — in terms of its relative cost to maintain its cleanliness.
Perhaps the most common error managers make when planning restroom upgrades is focusing on first costs. Over the life of a restroom, first costs in most applications are small, relative to operating and maintenance costs.
Focusing too heavily on an upgrade project's first costs also can result in a restroom design that does not allow managers to achieve long-term savings and hygiene goals. In many cases, even slight increases in first costs can result in very significant decreases in long-term operating and maintenance costs.
2. Plumbing: Water-Conservation Strategies
I'm Dan Hounsell, editor of Maintenance Solutions magazine. Today's topic is, water conservation strategies.
Maintenance and engineering managers already have begun to master the ins and outs of energy efficiency. But energy isn't the last word when it comes saving resources and operating a greener facility. Water efficiency is quickly growing as a green building and operations strategy.
A comprehensive water-management plan is the key to using water efficiently. Managers can start by gathering stakeholders in the organization to develop a list of water-management goals, incorporate water efficiency into long-term facility operation objectives, and address the resources necessary to achieve water-saving goals.
Understanding the price of water and wastewater is important when evaluating project cost effectiveness. Managers can determine costs by checking water bills and contacting utilities. They can collect data from waters meters — or submeters, if available — to calculate the facility's total annual water use and identify seasonal trends or abnormalities.
Restrooms, locker rooms, and other areas with plumbing fixtures offer obvious options for water efficiency. Besides regularly checking these areas for leaks, retrofitting restrooms with more water'efficient plumbing fixtures can produce significant water savings, as well as reduced energy costs from heating the water for sinks and showers.
WaterSense labeled models of tank'type toilets, flush urinals, and showerheads are independently certified to use at least 20 percent less water, and they perform as well as or better than standard models.
WaterSense labeled faucets and accessories use about 30 percent less water than conventional lavatory faucets. As with all WaterSense labeled products, each model is certified to meet strict criteria for efficiency and performance. A 100'employee office building that installs WaterSense labeled flushing urinals could save 26,000 gallons of water per year based on an average of two flushes per day.
3. ADA: Successful Restroom Renovations
I'm Dan Hounsell, editor of Maintenance Solutions magazine. Today's topic is, ADA and successful restroom renovations.
Restroom renovations in institutional and commercial facilities offer maintenance and engineering managers major opportunities to produce numerous benefits. Among these benefits is compliance with the Americans with Disabilities Act, or ADA. To meet ADA requirements during renovation, managers must consider occupant count, fixture requirements, space requirements, and structural requirements.
For example, most ADA-compliance renovations result in the loss of a stall or a urinal as a result of changes to meet the 5-foot diameter requirement for stalls. If the number of existing fixtures is appropriate for the code governing the area population, the loss of a stall might require added construction costs.
Structural requirements also come into play with grab bars required in the ADA stall. Often, walls must be reinforced to accommodate the potential weight-bearing capacities of these bars.
Omitting reinforcement of existing walls when installing grab bars is problematic. For example, in one college's public restroom, the grab bar in the handicap stall was detached and hanging from the wall.
The grab bar had been installed into the wall using only mollies, which obviously could not support weight applied to the grab bar. It not only cost more money to rectify the situation at that point, but it also created a hazard and an inconvenience for the public.
4. Understanding Key Plumbing Upgrade Considerations
I'm Steve Schuster, associate editor of Maintenance Solutions magazine. Today's topic discusses plumbing and restroom maintenance.
Many institutional and commercial facilities are installing a new generation of water-efficient plumbing fixtures — including flush valves, urinals, and faucets — at an ever-increasing rate. Their goals most often are to curtail water use by plumbing systems, reduce utility costs and improve the organization's overall sustainability.
But to ensure that these products deliver the desired benefits to the organization and the environment, maintenance and engineering managers who are making product selections need to carefully consider the maintenance impact these products are likely to have.
As maintenance and water costs rise, managers are increasingly installing pressure gages and flow meters at strategic locations in their buildings' plumbing systems to monitor the flow of water. Once managers are certain all of these readings are at normal levels, the next step is to look at individual fixtures and assess their condition. The first steps in effective troubleshooting involve knowing baseline flow readings, and monitoring, recording, and comparing the current readings.
Other efficiency considerations include lowering water use by replacing the aerator on the tap with a new one at a cost of a few dollars. The installation yields a new flow rate of one-half gpm. The flow is reduced by 3-1/2 gallons per minute.
Even if the valve operates just three minutes a day for 250 days per year, the annual savings from that level of operation would be more than 2,600 gallons. Ten faucets operating at that level would multiply the savings to 26,000 gallons.
Hygiene is also a critical component to successful restroom maintenance. Daily cleaning of the toilet seat, bowl, fixtures, and urinals is important to maintain an antiseptic, odor-free restroom.
