Manual Slide Hammer

To install Solinst Drive-Point Piezometers inexpensively, the Manual Slide Hammer can be used. The 21 lb (9.5 kg) slide hammer and all other equipment can easily be transported in a car or truck to most sites.

A 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.



Solinst supplies 3/4" NPT Delrin caps, and stainless steel couplings and extensions. These accessories can also be locally sourced at plumbing and hardware stores.


Depth Limitations

Drive-point Piezometers are not suitable for all sites. The depth limitations vary with soil conditions and the drive method used.


Sampling Within Narrow Diameters

Direct-push sampling has quickly become a popular way to obtain groundwater samples. However, sampling within drivepoints requires a narrow diameter sampler. Solinst offers several options for this specific sampling application.


Peristaltic Pump, Model 410

The Peristaltic Pump uses the suction lift principle. Suitable for 1/4" (6 mm) ID or larger diameters. The Peristaltic Pump provides a regulated and steady flow. It will lift water up to 32 ft. (10 m) at sea level.


Mini Inertial Pump, Model 404

The Mini Inertial Pump consists of a check valve and tubing that is rapidly raised and lowered to lift a sample. The Mini Inertial Pump suits wells as narrow as 3/8" (9.5 mm) ID and works to depths of 100 ft. (30 m).


Miniature Point Source Bailer, Model 429

The 1/2" (12 mm) dia. stainless steel bailer works very well in the 615 N or 615 SN. The bottom emptying device permits a regulated, steady flow.


Hydraulic Head

Water levels can be measured in most of the Drive-Points described, using a Solinst 101 Water Level Meter, or 102 or 102M Mini Laser Marked Coaxial Cable Water Level Meter. 1" to 3/4" reducer couplings are available for installing a Levelogger in a section of 1" extension pipe (NPT and BSPT options).
