So this is my 2nd hyrdromax extreme x40 and over time the valve at the top has gotten small crack from the top from just daily use causing air to leak through the upper part of the valve where you can remove the detachable black valve thing to clean.. but it is the outer part that fits into and I can't figure out if you can take apart the entire top assembly or not. Bathmats is not willing to help under warranty as its been past the point and I feel for spending around $350-400 its kinda ridiculous I have to pay to ship it to the UK but also pay for the repairs/new pump with them. Anyone else have this problem and have an "do it yourself" solution? thanks!View attachment 1828484
