Product Options


The Model 615 Drive Point Piezometer is designed to provide an inexpensive solution to monitoring shallow groundwater and soil vapour in suitable applications.

Solinst Drive-Point Piezometers can be used for short term monitoring applications, but are more commonly installed as permanent well points.

The Drive-Points attach to inexpensive 20 mm (3/4”) NPT steel drive pipe which is widely available through local plumbing and hardware stores.

When polyethylene or PTFE/FEP lined tubing is attached to the stainless steel drive point, high quality samples can be obtained. Groundwater sampling and hydraulic head measurements can be taken within the tubing using small diameter equipment.

Drive Point Piezometers can be driven into the ground with any direct push or drilling technology, including the Manual Slide Hammer. To avoid smearing of the screen or clogging during installation, a shielded version is also available.

Manual Slide Hammer

The Manual Slide Hammer can be used, in the most inexpensive installations, to install the Drive Point Piezometers. The heavy duty drive head is used, on which the slide hammer impacts and a tubing by-pass ensures that the tubing does not get damaged during installation.

  • 1ft screened extensions to lengthen the screened intake, with or without a barb
  • 25lbs slide hammer
  • A drive head assembly, including a drive head, 2 ft drive extension and a tubing bypass for installing with tubing
  • Sample tubing is a barb or compression fitting is being used (so sample water/vapour does come into contact with the pipe extensions)

For monitoring water levels:

  • 102 Water Level Meters with 10mm Probe
  • A 1” to ¾” stainless steel reducer coupling to install a Levelogger in a 1” drive extension section.

Sampling options include:

  • 410 Peristatic pump
  • 403 Mini inertial pump
  • Narrow diameter 429 Point-Source Bailer
The 601 and 615 are designed for permanent monitoring. So, neither are reusable, but the 615 can pulled out mechanically. However, grouting is the most favourable method of decommission on both of these pieces of equipment. The 660 Drive-point Profiler is a short-term monitoring point, therefore the hole left behind can be easily grouted using a grout tip Drive-point profiler.
The depth that these can be installed to depends on the material in which they are being installed in. Typically, you will get a deeper installation in peat over other ground materials.
