Phoned at 8.00in morning and the lady phoned back and was very polite & helpful. Engineer would call when on his way ......Blow me he arrived at 10.13am & was finished at 10.35am "yes" a simple (ish) job but showed me what he had done. Was polite, clean & finished with (luckily) no parts replaced this time....I did say I would get the boiler replaced next time as about 10 years old now!!!!? Mr Nathan Forbes (engineer) I dob my hat to you as you have restored my faith in engineers???No blowing thro, teeth or saying job is too big?.......Brilliant ,Brilliant. & Thank you Plumbing Force.
