From the power consumption point of view, is there a way of optimising use of the hot water system?
Is it necessary to de-grease the kitchen sink outlet periodically?
Can I do my own garden plumbing?
If on electricity contact your supplier and ask for advice on the best power tariff.
Not really. Prevention is better then cure- grease should not be put down the pipe. Products like Drano are effective in de-greasing but should be used with EXTREME CAUTION. I've known people to be blinded by the highly-reactive Sodium hydroxide component of de-greasers.
