Scale clobbered from both sides

FARMERS in hard water areas could benefit from the DP-13 descaling pump from Rigid, which is described as being suitable for cleaning any closed circuit heating system.

The unit incorporates a manual flow reverser – said to allow the scale to be attacked from both sides – and includes a 13 litre capacity tank and 2m-long re-reinforced hoses with a 1/2in coupling.

Additional 3/8in and 3/4in couplings are supplied with the unit. The DP-13 weighs in at 2.7kg (6lb) and, except for the motor, is made of acid-resistant plastic. Price is £280 (01462-485335).
