Following on from our recent visit, our engineer has advised that a desludge of your system is required. Please note, this price is based on no access restrictions for a 6-wheeler vehicle and the unit is located within 30m of hard standing ground (additional hose can be provided with prior notice). The job will usually be completed within 5 -10 working days and we would require payment prior to our attendance. Quotations are valid for 14 days. Should you wish to proceed or require further information, please do not hesitate to contact us. This includes 2000 gallons which is usually sufficient, however any additional gallonage will be discussed with you before any additional costs are incurred.
