White King Cistern Block available good supermarkets, these fit perfectly inside filter housing. |
3/4" Water Screen Filter available from H2O SHOP on eBay for $20.90 inc post. These are rated at 140psi so much more suitable than my first attempt. |
John Guest Non-Return Valve around $14 at caravan spares. |

| This is the way I did the job by intercepting the main water feed to the toilet flush and inserting the filter canister with a non-return valve to stop any chance of the cleanser entering the water system. There is insufficient room in the toilet enclosure to fit the required plumbing and also there would be water spillage when replacing the cistern block so I thought it was best left under the van. I also fitted a stopcock before the filter to facilitate replacing the fragrance block. I had most of the fittings needed to connect it up just had to source 3/4" to 1/2" reducers to fit the filter to the JG fittings. I could not get any plastic versions but they may be available somewhere. Now every flush has a pleasing aroma :-) This was based on an idea told to me by Trevor Watson from Aussie Baby Boomers Forum |
