Harwil Flow Switch - Short Probe Version

 

This is the short probe Harwil Flow switch which is not very common in Europe but found used with Gecko, HydroQuip spa control systems combined with Laing circulation pumps and heaters. Can be found threaded into either white or clear PVC plastic plumbing tee's. 


Note. There are three main types of Flow Switch that look very simular but are not so please check the length of the probe arm and diameter of the threaded connection before ordering your replacement part. This switch does NOT fit the other complete Flow Switch models in this category with the clear PVC tee's as these versions have a 1" outer thread diameter.



Dimensions


Length of Grey Probe Arm - 35mm (1-3/8")

Total Length of Switch - 80mm

Outer Diameter of Thread - 20mm (3/4")



Connections

 

A cable is not supplied with this replacement part so you will also need to retain the cable from your original switch and crimp to the new one using the two small crimps supplied on the top of the switch. In terms of plumbing connection it has a 3/4 MPT thread, Teflon tape must be used to seal this connection.



Common on Spa Brands


Known hot tub brands that often have this fitted are Sundance Spas, Jacuzzi Spas and few others.

 

 

Additional Information


Flow switches are normally quite durable so before replacing this switch on your spa be sure that there is not a low flow problem on your spa such as dirty filters, low water level or a blockage in the pipework.
