I met David at the NEC Home Building and Renovation Show. Very friendly and helpful. David has been out to site and helped us plan out our entire drainage system and offered very good advice over other tank manufacturers. His knowledge and experience is very evident. The delivery of the tank and sample chamber couldn't have gone more smoothly and nothing was too much trouble for the delivery driver. Thank you to all of the team at We Build It Ltd.
