Detailed Breakdown on the Proper Installation of an Amalgam Separator on a Dry-Vacuum Pump- Step 4- Planning

If you have been following this Blog Series, you have chosen to join us on the educational journey of the proper installation of an amalgam separator on a dry-vacuum system.

Step 1- Location- Part 1 of this Blog Series spoke about where in the mechanical room you will locate the inlet pipe from chairs and determine the appropriate approach to an installation based on its location.

Step 1– Location- Part 2 discussed where amalgam separators belong in the evacuation line system, common mistakes made by Non-C.A.S.S. Service Technicians and space-saving installation tips.

Step 2 – Hose illustrated the importance of choosing the right evacuation hose for your amalgam separator installation.

Step 3 – Fittings offers tips on selecting the right parts to complete your LibertyBOSS installation like an M.A.R.S Certified Amalgam Separator Specialist.

Now that we have selected the hose and correct fittings we will be using for the installation, Step 4 will be reviewing simple tips on how to make your installation go as smoothly as possible.

Planning Stage

“Measure twice and cut once,” though a vague statement, the message is still the same. Planning for an installation is an essential part of the process. In the first two segments of this Blog Series, we taught you how to choose the right location for your amalgam separator installation. Once an area is selected, you will have to plan the course of action, the correct tools and parts needed to complete your installation.

Ready for Your Close Up?

It is recommended to take a broad photo of the mechanical room a few days before the installation. Using the correct angle will allow you to choose the exact parts you require when you are shopping at your local plumbing supply, pool supply or hardware store. If you haven’t gone shopping for plumbing parts before, it is recommended to try to source the parts online first. Planning your shopping ahead of time will save you time, money and frustration.

Note: You don’t have to be a professional photographer, but a board and clear photo of the mechanical room will minimize guessing on parts and tools, which will allow the installation to go smoother. The photo on the left is an example of a picture that was too focused on one aspect of the mechanical room. The photo on the right is an example of an ideal photo for planning an installation.

Planning Amalgam Separator Installation

One Step at a Time

Begin to prepare your installation by following the flow of water and air from your operatory to the suction pump. Using the “Proper Installation of a M.A.R.S LibertyBOSS on a Dry-Vacuum Pump” video as an example, we planned our required parts and tools by noting everything from the inlet from chairs to the inlet of the Midmark Dry-Vacuum.

  1. The following is a thought process used when deciding on the required parts for the installation of the M.A.R.S LibertyBOSS in the video;
    Inlet from chairs; Inlet pipe is copper with a rubber coupler converting it to 1 ½” flexible PVC hose. Use the existing hose and parts for the inlet installation of the LibertyBOSS.                                                                                                                                                                           a. Quick connect and 1 ½” barbed hose fitting required to complete hose attachment on the inlet of the LibertyBOSS.
  2. The outlet of LibertyBOSS; space is restricted, a 90-degree elbow off the LibertyBOSS outlet will allow for a tighter and cleaner installation.                                                                                                                                                                                                                                            a. Quick connect and 1 ½” barbed hose fitting required to complete hose attachment on the outlet of the LibertyBOSS.
  3.  Inlet to pump has 1 ½” barbed fittings attached, but the remainder of the existing hose may not be long enough to span from LibertyBOSS outlet to pump inlet. Purchase extra 5’ length of 1 ½” hose to ensure you will have enough on the day of installation.

Installation Part List

Based on the above breakdown the following part list was formed;

2- 1 ½” barbed to threaded hose adapters

2- hose clamps

2- Sets of quick connects

1- 90-degree elbow

1- 5’ length of flexible PVC hose

Install Parts


The Right Tools

Having the right tools for any installation will make the entire process go a whole lot smoother. The following list of tools is required for a standard installation.

Channel Locks

These type of pliers are commonly used in plumbing due to their ability to quickly adjust to the size of a pipe fitting. Though M.A.R.S recommends hand tightening every joint, a channel lock plier is handy to have in case an existing fitting needs to be removed.

5/16 Nut Driver

The 5/16 nut driver is used to tighten the hose clamps over the hose and barbed fittings. A flat head screwdriver can also be used, but a 5/16 nut driver will make the installation a lot easier.

Heat Gun

A heat gun can often be found in the paint section of a hardware store; they are inexpensive and extremely useful during an amalgam separator installation. M.A.R.S recommends any installer includes a heat gun to their tool belt, as it makes working with PVC hose a lot easier.


Lubricant/sealants are not necessary for an amalgam separator installation, but it does help with making it easier on the installer. The purpose of the lubricant/sealant is to allow a barbed fitting to be inserted into a PVC hose with minimum effort, all the while adding an additional level of protection against leaks.

If you do not have a lubricant/sealant available; soap, Vaseline, even saliva will assist in inserting the barbed fitting into a PVC hose.

Hose Cutter

Many appropriate tools can be used to cut flexible PVC hose; utility knife, hacksaw or heavy scissors. A hose or pipe cutter makes the process easier and safer.


Part 5 -The Installation

The planning is over, not it is time for the fun part, the installation. Our next blog will be discussing the Installation process of the M.A.R.S LibertyBOSS on to a dry-vacuum system.
