Three questions, but I have included them in the one post because they are related.
I purchased a house in Code Postale 33580 back in October 2016. A French architect was engaged prior to purchase, but work has yet to commence.The two plumbers invited by the archiect (who will project manage the work co-ordinating the various trades)to submit devis not only want to choose the showers, sinks, basins, water heaters etc. but are selecting the most expensive brands and charging (fitting the components is a separate element in the devis) more(without VAT @10% ) than plumber's merchants price inclusive of VAT @ 20%.. I welcome other subscribers comments.
On a technical issue do any subscribers have any experience using a macerator unit in an ensuite (WC, basin, sink) to a fosse septique?
The fosse is "non-conforme", I prefer a "micro-station" because my research suggests that a filtyer bed is not a cost effective solution. I expect to visit the house for a few days every month of the year and most of June to August. Do any subscribers have any experience using solar power to supply the "micro-station" or is a once a month flush sufficient to keep the system working?
