Does your system still fit your needs?
Has demand changed, performance become less reliable, or maintenance become more frequent? Tell PPT what you’re seeing and what the system needs to do now. We’ll review the current system and what has changed to help determine whether repair, an upgrade, expansion, or replacement makes sense.
Reasons to review your system
Common issues that can point to repair, upgrade, expansion, or replacement.
Repairs, maintenance & parts
The same faults keep returning, maintenance takes more time and money, or parts are obsolete or difficult to source.
Review your systemCapacity & reliability
Demand has grown or fallen. The system struggles to keep up, recover between uses, or provide consistent output—or is now larger than you need.
Review your requirementsProcess changes & expansion
More users, new equipment, different quality requirements, or facility changes have altered what the system needs to do.

Repair, upgrade, expand, or replace?
A repair may address your immediate problem, but will your system still meet your requirements? Start with what it can still support, what has changed, and whether parts and ongoing support are available.
What does your
process need now?
Review required water or solvent quality, daily and peak use, points of use, and planned changes. Include available space, utilities, distribution, and service access so the discussion covers systems that may be too small, too large, or difficult to adapt.
For water systems, include storage, recovery, and feedwater conditions. For solvent systems, share the solvents used, current configuration, workflow, and facility constraints.
Maintenance & support
What is it costing you to keep your system running?
Look at repair history, maintenance costs, recurring faults, and the effect on daily work. Consider whether parts and technical support remain available, alongside the requirements an upgrade or replacement would need to meet.
Repair history & maintenance costs
Share recurring faults, recent work, consumable changes, and known costs. Include how often the same problem returns and what it takes to address it.
Impact on daily work
Describe interruptions, inconsistent output, slow recovery, or work that has to wait for the system. Explain how those problems affect your application.
Parts availability & support
Identify components that are difficult to source, discontinued, or hard to service. Share any part numbers and information from the manufacturer or current service provider.
Future requirements
Include expected demand, new equipment, process changes, and planned facility work. Compare the work needed now with what the system will need to support later.
If several of these are changing at once, it may be time to compare continued repair against an upgrade or replacement.

What to share with PPT
Send what you have. Photos and existing records are a useful starting point, even if some details are unknown.
Identify the system
- Manufacturer, model, serial number, and approximate age
- System and nameplate photos
Describe current requirements
- Application, required quality, daily use, and peak demand
- Layout, available space, utilities, and service access
Share the operating history
- Recent faults, readings, maintenance, and repair records
- Known repair costs and difficult-to-source parts
Explain what is changing
- Planned changes, expansion, and timing constraints
- Available plans, specifications, or equipment schedules

A practical review of the system you already have
PPT designs, builds, and supports high-purity water and solvent systems. That work includes the equipment, facility requirements, maintenance, and parts needed over the life of a system.
Engineering and service in the same discussion
Bring repair and service records alongside the capacity and quality targets. Reviewing them together helps compare continued repair with an upgrade or replacement.
