You’ve cut holes in the wall, peeled back the layers of the substrates like an onion, run all the wiring, and installed all of the proper hardware. You’ve tested everything. Twice. You painstakingly put everything back together, screws have been screwed, the glue has been glued. You turn on your system and…nothing. This can’t be. You try again. Your tanks are drawing a blank. Now, because you unfortunately purchased (or had installed from the factory) an inferior product, you have to tear everything apart. Sadly, this scenario is not a new one in the world of RV owners. They will find the parts they need to help fix their rig and then when it comes time to hit the road, they break. At RecPro we know that RV ownership means repairs and upgrades. Sometimes as soon as you drive your beloved RV off the lot. That’s why we provide the best parts in the aftermarket industry. This is especially true with the items in our tank and tank parts line. Review: good - all good, excellent very fast shipping am sure they will work fine. thank you. Review: Not worth it - Only worked for a while.

Installing is a winter project for me. However, If your worried about which it is, your worrying over nothing. It doesn't matter. As a 50 yr veteran of fabricating/welding with more stainless than other alloys, I can tell you 304 is used for almost everything other than food grade. Then it pretty much becomes 316 any time sanitary is involved. And were a long way from that in these tanks. My suggestion is buy the product and don't worry about it. **Q: Do the sensors contain any Lead (Pb)?** A: Actually, lead is a very good conductor but no this product does not contain it. **Q: Can the sensors be removed and replaced if they become dirty?** A: I havent installed the sensors yet so wont know sometime after I fit them. From their design they look like it could be possible, however over long term rubber usually perishes & replacement may be warranted. Hope this feedback helps. **Q: Can I use these in place of the long probe sensors?** A: Yes you can but from my study the long sensors are better, I ended up going with sea level sensors that stick on the side of the tank ## Customer Reviews ### ⭐⭐⭐⭐⭐ good *by S***D on 5 June 2021* all good, excellent very fast shipping am sure they will work fine. thank you. ### ⭐ Not worth it *by S***Y on 12 February 2026* Only worked for a while.
