Hello

Do you really need to filter all your water ? The stuff you use to flush the loo ? The stuff you use to wash clothes ? I have cheap little filters on the loo to trap sand and other stuff from blocking the valve. I clean it about once a year or when it is obviously blocked. I bought a 5 stage osmosis unit from BricoMart in Castellon (same DIY chain as B&Q) for €99. This does the drinking water. I have replaced the filters once in 2 years. I bought a cheap water tester off ebay. This measures suspended solids. The filtered water is always better when compared to bottled water as to suspended solids. You can always buy the bottled stuff to drink neat if you have doubts. You usually boil the water in cooking, making tea etc so the filtered stuff will be fine. I hope that helps

Thanks David, to filter some of the water would need a complete replumb, & we didn't want to do that, we also need to have the water not smell as the house is used as a holiday let in the summer months........
I think our town water, in El Perello, is grey water, so not an option

Hello again. The town water I mentioned is taken from municipal drinking water taps. Most towns and villages have such a source.
Certainly not grey water. Usually there is a sign that says "agua potable"
To plumb the osmosis system in took me 30 mins. It just connects to the water source pipe and the waste pipe under the sink

Actually you do not pay for the water available from the fonts. Had the same complaints as yours in Gandesa but proved they were wrong. Cravanners, cyclists, motorists, tourists, locals, that water is available to all.

I would not believe what the locals say about the water being healthy.  The water here is full of lime deposits which can cause all sorts of problems like kidney stones or the bladder stones from which I suffered until they were removed.  Just take a look at the calcium scale in the bottom of your kettle if you do not use a filter.
