We had a complete RV holding tank electric waste gate valves, 3 inch drain pipe from the holding tanks, the storage box and much more installed on our DRV Mobile Suites Houston. I Love my Drain Master system and am so glad we put our faith in the company and its three amazing employees! The system is so simple and works amazing and the gray tank drains so fast going from a 2 inch pipe to a 3 inch pipe. While we were there we purchased a supplemental part to screw into the standard RV sewer system to go along with our complet... read more

I have used many different systems (including macerator pumps) over the past 13 years of RVing - the Drain Master RV sewer hose and cam-loc connectors are the best, much better than anticipated. Easy to hook up, quickly (very quickly) drains, easy and clean to unhook, and stores perfectly in the wet bay of my motorhome. The Drain Master customer support absolutely surpasses all other companies I deal with.

We added Drain Master electric valves to our 2025 Riverstone 442MC. No more getting on my hands and knees to drain our tanks. Now we can drain all four of our tanks with the push of a button. Mukul from DM Engineering was amazing to work with, met us for dinner and explained in detail how to install the system on our rig. He was available for calls and helped with other products/supplies needed to install the valves….these valves will make your life so much easier

I installed the hose storage on my unit and I could not be happier with it. It will save so much setup hassle and inconvenience now. Thanks for your help in this and check out the pictures.
