Harpic Toilet Block available good supermarkets, these fit perfectly inside the mesh strainer. |
Water Strainer available from Whitworths Marine Cat # 83568 $17.95 |
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 strainer canister with a non-return valve to stop any chance of the cleanser entering the water system. There was insufficient room in the toilet enclosure to fit the required plumbing and also there would be water spillage when replacing the Harpic block so I thought it was best left under the van. Now every flush has a pleasing aroma :-) This was based on an idea told to me by Trevor Watson from Aussie Baby Boomers Forum |
