Tecmark - Adjustable SPDT Hot Tub Pressure Switch, 1-5 psi - 3015

Tecmark – Adjustable SPDT Hot Tub Pressure Switch, 1-5 psi

The Tecmark 3015 is a replacement hot tub pressure switch with an SPDT relay, rated at 25A and fully adjustable between 1 and 5 psi. It has a 1/8″ MPT connection and a stainless steel pan, which helps extend the life of the switch.

If you are looking for a spa pressure switch where the pressure threshold can be set rather than being fixed, the Tecmark 3015 is built for exactly that.

What the Tecmark 3015 pressure switch does

The pressure switch is one of the most important pieces of safety equipment in your spa system. It constantly monitors the water flowing through the heater and helps protect critical components if a problem arises, such as overheating.

Because it plays a role in protecting the heater circuit, a pressure switch that matches your system’s requirements is worth checking carefully before you order a replacement.

Specifications and connection

The main technical details of the Tecmark 3015 are listed below.

• Relay type: SPDT
• Pressure thresholds: adjustable from 1 to 5 psi
• Maximum current rating: 25A
• Thread: 1/8″ NPT, with an outside diameter of 9.5 mm
• Pan material: stainless steel

The connection is described as a 1/8″ MPT thread, so compare it with the fitting on your existing switch before ordering.

How to choose the right replacement pressure switch

Start by looking at your current pressure switch and noting its relay type, its pressure range, its current rating and the size of its thread. The Tecmark 3015 suits a spa that needs an SPDT switch rated at 25A with a 1/8″ thread and an adjustable range of 1 to 5 psi.

Check that each of these values matches your original part. If the numbers differ, or you are not sure, this switch may not be the right choice for your system.

Adjustable setting and fitting notes

The 3015 can be adjusted across its 1 to 5 psi range, so the threshold can be set to suit your installation rather than being fixed at one value.

As the switch protects the heater, make sure it is fitted correctly and that the connection is properly made. If you are unsure about the installation, ask a qualified spa technician for help.
