Don't buy. If it dose not work like it dose not for us and turns the hot water cold. If you want a refund you can't open the packaging it gets shipped in. I waited for a month for it to turn up. Tried it. It made my shower worse and have been emailing back and forward for them to only offer a replacement at my cost of postage. No refund as I want and return the product. They suck and have made a simple process hard and painful. They suck.
